-/** \class QuaZip quazip.h <quazip/quazip.h>
- * This class implements basic interface to the ZIP archive. It can be
- * used to read table contents of the ZIP archive and retreiving
- * information about the files inside it.
- *
- * You can also use this class to open files inside archive by passing
- * pointer to the instance of this class to the constructor of the
- * QuaZipFile class. But see QuaZipFile::QuaZipFile(QuaZip*, QObject*)
- * for the possible pitfalls.
- *
- * This class is indended to provide interface to the ZIP subpackage of
- * the ZIP/UNZIP package as well as to the UNZIP subpackage. But
- * currently it supports only UNZIP.
- *
- * The use of this class is simple - just create instance using
- * constructor, then set ZIP archive file name using setFile() function
- * (if you did not passed the name to the constructor), then open() and
- * then use different functions to work with it! Well, if you are
- * paranoid, you may also wish to call close before destructing the
- * instance, to check for errors on close.
- *
- * You may also use getUnzFile() and getZipFile() functions to get the
- * ZIP archive handle and use it with ZIP/UNZIP package API directly.
- *
- * This class supports localized file names inside ZIP archive, but you
- * have to set up proper codec with setCodec() function. By default,
- * locale codec will be used, which is probably ok for UNIX systems, but
- * will almost certainly fail with ZIP archives created in Windows. This
- * is because Windows ZIP programs have strange habit of using DOS
- * encoding for file names in ZIP archives. For example, ZIP archive
- * with cyrillic names created in Windows will have file names in \c
- * IBM866 encoding instead of \c WINDOWS-1251. I think that calling one
- * function is not much trouble, but for true platform independency it
- * would be nice to have some mechanism for file name encoding auto
- * detection using locale information. Does anyone know a good way to do
- * it?

- * Argument \a ioApi specifies IO function set for ZIP/UNZIP
- * package to use. See unzip.h, zip.h and ioapi.h for details. Note

- * The file path argument was changed to be of type \c voidpf, and
- * QuaZip passes a QIODevice pointer there. This QIODevice is either
- * set explicitly via setIoDevice() or the QuaZip(QIODevice*)
- * constructor, or it is created internally when opening the archive
- * by its file name. The default API (qioapi.cpp) just delegates
- * everything to the QIODevice API. Not only this allows to use a
- * QIODevice instead of file name, but also has a nice side effect
- * of raising the file size limit from 2G to 4G.

-/// A file inside ZIP archive.
-/** \class QuaZipFile quazipfile.h <quazip/quazipfile.h>
- * This is the most interesting class. Not only it provides C++
- * interface to the ZIP/UNZIP package, but also integrates it with Qt by
- * subclassing QIODevice. This makes possible to access files inside ZIP
- * archive using QTextStream or QDataStream, for example. Actually, this
- * is the main purpose of the whole QuaZIP library.
- *
- * You can either use existing QuaZip instance to create instance of
- * this class or pass ZIP archive file name to this class, in which case
- * it will create internal QuaZip object. See constructors' descriptions
- * for details. Writing is only possible with the existing instance.
- *
- * Note that due to the underlying library's limitation it is not
- * possible to use multiple QuaZipFile instances to open several files
- * in the same archive at the same time. If you need to write to
- * multiple files in parallel, then you should write to temporary files
- * first, then pack them all at once when you have finished writing. If
- * you need to read multiple files inside the same archive in parallel,
- * you should extract them all into a temporary directory first.
- *
- * \section quazipfile-sequential Sequential or random-access?
- *
- * At the first thought, QuaZipFile has fixed size, the start and the
- * end and should be therefore considered random-access device. But
- * there is one major obstacle to making it random-access: ZIP/UNZIP API
- * does not support seek() operation and the only way to implement it is
- * through reopening the file and re-reading to the required position,
- * but this is prohibitively slow.
- *
- * Therefore, QuaZipFile is considered to be a sequential device. This
- * has advantage of availability of the ungetChar() operation (QIODevice
- * does not implement it properly for non-sequential devices unless they
- * support seek()). Disadvantage is a somewhat strange behaviour of the
- * size() and pos() functions. This should be kept in mind while using
- * this class.

- * \a zip is the pointer to the existing QuaZip object. This
- * QuaZipFile object then can be used to read current file in the
- * \a zip or to write to the file inside it.
- *
- * \warning Using this constructor for reading current file can be
- * tricky. Let's take the following example:
- * \code
- * QuaZip zip("archive.zip");
- * zip.open(QuaZip::mdUnzip);
- * zip.setCurrentFile("file-in-archive");
- * QuaZipFile file(&zip);
- * file.open(QIODevice::ReadOnly);
- * // ok, now we can read from the file
- * file.read(somewhere, some);
- * zip.setCurrentFile("another-file-in-archive"); // oops...
- * QuaZipFile anotherFile(&zip);
- * anotherFile.open(QIODevice::ReadOnly);
- * anotherFile.read(somewhere, some); // this is still ok...
- * file.read(somewhere, some); // and this is NOT
- * \endcode
- * So, what exactly happens here? When we change current file in the
- * \c zip archive, \c file that references it becomes invalid
- * (actually, as far as I understand ZIP/UNZIP sources, it becomes
- * closed, but QuaZipFile has no means to detect it).
- *
- * Summary: do not close \c zip object or change its current file as
- * long as QuaZipFile is open. Even better - use another constructors
- * which create internal QuaZip instances, one per object, and
- * therefore do not cause unnecessary trouble. This constructor may
- * be useful, though, if you already have a QuaZip instance and do
- * not want to access several files at once. Good example:
- * \code
- * QuaZip zip("archive.zip");
- * zip.open(QuaZip::mdUnzip);
- * // first, we need some information about archive itself
- * QByteArray comment=zip.getComment();
- * // and now we are going to access files inside it
- * QuaZipFile file(&zip);
- * for(bool more=zip.goToFirstFile(); more; more=zip.goToNextFile()) {
- * file.open(QIODevice::ReadOnly);
- * // do something cool with file here
- * file.close(); // do not forget to close!
- * }
- * zip.close();
- * \endcode

+/// A file inside ZIP archive.
+/** \class QuaZipFile quazipfile.h <quazip/quazipfile.h>
+ * This is the most interesting class. Not only it provides C++
+ * interface to the ZIP/UNZIP package, but also integrates it with Qt by
+ * subclassing QIODevice. This makes possible to access files inside ZIP
+ * archive using QTextStream or QDataStream, for example. Actually, this
+ * is the main purpose of the whole QuaZIP library.
+ *
+ * You can either use existing QuaZip instance to create instance of
+ * this class or pass ZIP archive file name to this class, in which case
+ * it will create internal QuaZip object. See constructors' descriptions
+ * for details. Writing is only possible with the existing instance.
+ *
+ * Note that due to the underlying library's limitation it is not
+ * possible to use multiple QuaZipFile instances to open several files
+ * in the same archive at the same time. If you need to write to
+ * multiple files in parallel, then you should write to temporary files
+ * first, then pack them all at once when you have finished writing. If
+ * you need to read multiple files inside the same archive in parallel,
+ * you should extract them all into a temporary directory first.
+ *
+ * \section quazipfile-sequential Sequential or random-access?
+ *
+ * At the first thought, QuaZipFile has fixed size, the start and the
+ * end and should be therefore considered random-access device. But
+ * there is one major obstacle to making it random-access: ZIP/UNZIP API
+ * does not support seek() operation and the only way to implement it is
+ * through reopening the file and re-reading to the required position,
+ * but this is prohibitively slow.
+ *
+ * Therefore, QuaZipFile is considered to be a sequential device. This
+ * has advantage of availability of the ungetChar() operation (QIODevice
+ * does not implement it properly for non-sequential devices unless they
+ * support seek()). Disadvantage is a somewhat strange behaviour of the
+ * size() and pos() functions. This should be kept in mind while using
+ * this class.

+ * \a zip is the pointer to the existing QuaZip object. This
+ * QuaZipFile object then can be used to read current file in the
+ * \a zip or to write to the file inside it.
+ *
+ * \warning Using this constructor for reading current file can be
+ * tricky. Let's take the following example:
+ * \code
+ * QuaZip zip("archive.zip");
+ * zip.open(QuaZip::mdUnzip);
+ * zip.setCurrentFile("file-in-archive");
+ * QuaZipFile file(&zip);
+ * file.open(QIODevice::ReadOnly);
+ * // ok, now we can read from the file
+ * file.read(somewhere, some);
+ * zip.setCurrentFile("another-file-in-archive"); // oops...
+ * QuaZipFile anotherFile(&zip);
+ * anotherFile.open(QIODevice::ReadOnly);
+ * anotherFile.read(somewhere, some); // this is still ok...
+ * file.read(somewhere, some); // and this is NOT
+ * \endcode
+ * So, what exactly happens here? When we change current file in the
+ * \c zip archive, \c file that references it becomes invalid
+ * (actually, as far as I understand ZIP/UNZIP sources, it becomes
+ * closed, but QuaZipFile has no means to detect it).
+ *
+ * Summary: do not close \c zip object or change its current file as
+ * long as QuaZipFile is open. Even better - use another constructors
+ * which create internal QuaZip instances, one per object, and
+ * therefore do not cause unnecessary trouble. This constructor may
+ * be useful, though, if you already have a QuaZip instance and do
+ * not want to access several files at once. Good example:
+ * \code
+ * QuaZip zip("archive.zip");
+ * zip.open(QuaZip::mdUnzip);
+ * // first, we need some information about archive itself
+ * QByteArray comment=zip.getComment();
+ * // and now we are going to access files inside it
+ * QuaZipFile file(&zip);
+ * for(bool more=zip.goToFirstFile(); more; more=zip.goToNextFile()) {
+ * file.open(QIODevice::ReadOnly);
+ * // do something cool with file here
+ * file.close(); // do not forget to close!
+ * }
+ * zip.close();

- * Note about libpng version numbers:
- *
- * Due to various miscommunications, unforeseen code incompatibilities
- * and occasional factors outside the authors' control, version numbering
- * on the library has not always been consistent and straightforward.
- * The following table summarizes matters since version 0.89c, which was
- * the first widely used release:

- * Henceforth the source version will match the shared-library major
- * and minor numbers; the shared-library major version number will be
- * used for changes in backward compatibility, as it is intended. The
- * PNG_LIBPNG_VER macro, which is not used within libpng but is available
- * for applications, is an unsigned integer of the form xyyzz corresponding
- * to the source version x.y.z (leading zeros in y and z). Beta versions
- * were given the previous public release number plus a letter, until
- * version 1.0.6j; from then on they were given the upcoming public
- * release number plus "betaNN" or "rcNN".
- *
- * Binary incompatibility exists only when applications make direct access
- * to the info_ptr or png_ptr members through png.h, and the compiled
- * application is loaded with a different version of the library.
- *
- * DLLNUM will change each time there are forward or backward changes
- * in binary compatibility (e.g., when a new feature is added).
- *
- * See libpng-manual.txt or libpng.3 for more information. The PNG
- * specification is available as a W3C Recommendation and as an ISO
- * Specification, <http://www.w3.org/TR/2003/REC-PNG-20031110/

- * Y2K compliance in libpng:
- * =========================
- *
- * September 27, 2012
- *
- * Since the PNG Development group is an ad-hoc body, we can't make
- * an official declaration.
- *
- * This is your unofficial assurance that libpng from version 0.71 and
- * upward through 1.5.13 are Y2K compliant. It is my belief that
- * earlier versions were also Y2K compliant.
- *
- * Libpng only has two year fields. One is a 2-byte unsigned integer
- * that will hold years up to 65535. The other holds the date in text
- * format, and will hold years up to 9999.
- *
- * The integer is
- * "png_uint_16 year" in png_time_struct.
- *
- * The string is
- * "char time_buffer[29]" in png_struct. This will be no
- * longer used in libpng-1.6.0 and will be removed from libpng-1.7.0.
- *
- * There are seven time-related functions:
- * png.c: png_convert_to_rfc_1123() in png.c
- * (formerly png_convert_to_rfc_1152() in error)
- * png_convert_from_struct_tm() in pngwrite.c, called in pngwrite.c
- * png_convert_from_time_t() in pngwrite.c
- * png_get_tIME() in pngget.c
- * png_handle_tIME() in pngrutil.c, called in pngread.c
- * png_set_tIME() in pngset.c
- * png_write_tIME() in pngwutil.c, called in pngwrite.c
- *
- * All handle dates properly in a Y2K environment. The
- * png_convert_from_time_t() function calls gmtime() to convert from system

- *
- * This has no effect on the way pixels are written into a PNG output
- * datastream. The color samples in a PNG datastream are never premultiplied
- * with the alpha samples.
- *
- * The default is to return data according to the PNG specification: the alpha
- * channel is a linear measure of the contribution of the pixel to the
- * corresponding composited pixel. The gamma encoded color channels must be
- * scaled according to the contribution and to do this it is necessary to undo
- * the encoding, scale the color values, perform the composition and reencode
- * the values. This is the 'PNG' mode.
- *
- * The alternative is to 'associate' the alpha with the color information by
- * storing color channel values that have been scaled by the alpha. The
- * advantage is that the color channels can be resampled (the image can be
- * scaled) in this form. The disadvantage is that normal practice is to store
- * linear, not (gamma) encoded, values and this requires 16-bit channels for
- * still images rather than the 8-bit channels that are just about sufficient if
- * gamma encoding is used. In addition all non-transparent pixel values,
- * including completely opaque ones, must be gamma encoded to produce the final
- * image. This is the 'STANDARD', 'ASSOCIATED' or 'PREMULTIPLIED' mode (the
- * latter being the two common names for associated alpha color channels.)
- *
- * Since it is not necessary to perform arithmetic on opaque color values so
- * long as they are not to be resampled and are in the final color space it is
- * possible to optimize the handling of alpha by storing the opaque pixels in
- * the PNG format (adjusted for the output color space) while storing partially
- * opaque pixels in the standard, linear, format. The accuracy required for
- * standard alpha composition is relatively low, because the pixels are
- * isolated, therefore typically the accuracy loss in storing 8-bit linear
- * values is acceptable. (This is not true if the alpha channel is used to
- * simulate transparency over large areas - use 16 bits or the PNG mode in
- * this case!) This is the 'OPTIMIZED' mode. For this mode a pixel is
- * treated as opaque only if the alpha value is equal to the maximum value.
- *
- * The final choice is to gamma encode the alpha channel as well. This is
- * broken because, in practice, no implementation that uses this choice
- * correctly undoes the encoding before handling alpha composition. Use this
- * choice only if other serious errors in the software or hardware you use
- * mandate it; the typical serious error is for dark halos to appear around
- * opaque areas of the composited PNG image because of arithmetic overflow.
- *

- *
- * The inverse of the value is always used to provide a default for the PNG file

- * to override the PNG gamma information.
- *
- * When the ALPHA_OPTIMIZED mode is selected the output gamma is used to encode

- *
- * When the standard Porter Duff handling is requested with mode 1 the output

- * as a default for input data that has no gamma information. The linear output
- * encoding will be overridden if png_set_gamma() is called - the results may be
- * highly unexpected!
- *
- * The following numbers are derived from the sRGB standard and the research
- * behind it. sRGB is defined to be approximated by a PNG gAMA chunk value of
- * 0.45455 (1/2.2) for PNG. The value implicitly includes any viewing
- * correction required to take account of any differences in the color
- * environment of the original scene and the intended display environment; the
- * value expresses how to *decode* the image for display, not how the original
- * data was *encoded*.
- *
- * sRGB provides a peg for the PNG standard by defining a viewing environment.
- * sRGB itself, and earlier TV standards, actually use a more complex transform
- * (a linear portion then a gamma 2.4 power law) than PNG can express. (PNG is
- * limited to simple power laws.) By saying that an image for direct display on
- * an sRGB conformant system should be stored with a gAMA chunk value of 45455
- * (11.3.3.2 and 11.3.3.5 of the ISO PNG specification) the PNG specification
- * makes it possible to derive values for other display systems and
- * environments.
- *
- * The Mac value is deduced from the sRGB based on an assumption that the actual
- * extra viewing correction used in early Mac display systems was implemented as
- * a power 1.45 lookup table.
- *
- * Any system where a programmable lookup table is used or where the behavior of
- * the final display device characteristics can be changed requires system
- * specific code to obtain the current characteristic. However this can be
- * difficult and most PNG gamma correction only requires an approximate value.
- *
- * By default, if png_set_alpha_mode() is not called, libpng assumes that all
- * values are unencoded, linear, values and that the output device also has a
- * linear characteristic. This is only very rarely correct - it is invariably
- * better to call png_set_alpha_mode() with PNG_DEFAULT_sRGB than rely on the
- * default if you don't know what the right answer is!
- *
- * The special value PNG_GAMMA_MAC_18 indicates an older Mac system (pre Mac OS
- * 10.6) which used a correction table to implement a somewhat lower gamma on an
- * otherwise sRGB system.
- *
- * Both these values are reserved (not simple gamma values) in order to allow
- * more precise correction internally in the future.

- * point APIs, but the floating point API will also accept floating point

- *
- * png_set_expand_16(pp);
- * png_set_alpha_mode(pp, PNG_ALPHA_STANDARD, PNG_DEFAULT_sRGB);
- * This is a somewhat more realistic Jim Blinn inspired approach. PNG files
- * are assumed to have the sRGB encoding if not marked with a gamma value and
- * the output is always 16 bits per component. This permits accurate scaling
- * and processing of the data. If you know that your input PNG files were

- * output. For pixels that are not completely transparent (you just skip
- * those) you do the composition math using png_composite or png_composite_16
- * below then encode the resultant 8-bit or 16-bit values to match the output
- * encoding.
- *
- * Other cases
- * If neither the PNG nor the standard linear encoding work for you because
- * of the software or hardware you use then you have a big problem. The PNG
- * case will probably result in halos around the image. The linear encoding
- * will probably result in a washed out, too bright, image (it's actually too
- * contrasty.) Try the ALPHA_OPTIMIZED mode above - this will probably
- * substantially reduce the halos. Alternatively try:
- *
- * png_set_alpha_mode(pp, PNG_ALPHA_BROKEN, PNG_DEFAULT_sRGB);
- * This option will also reduce the halos, but there will be slight dark
- * halos round the opaque parts of the image where the background is light.
- * In the OPTIMIZED mode the halos will be light halos where the background
- * is dark. Take your pick - the halos are unavoidable unless you can get
- * your hardware/software fixed! (The OPTIMIZED approach is slightly
- * faster.)
- *
- * When the default gamma of PNG files doesn't match the output gamma.
- * If you have PNG files with no gamma information png_set_alpha_mode allows
- * you to provide a default gamma, but it also sets the ouput gamma to the
- * matching value. If you know your PNG files have a gamma that doesn't
- * match the output you can take advantage of the fact that
- * png_set_alpha_mode always sets the output gamma but only sets the PNG
- * default if it is not already set:
- *
- * png_set_alpha_mode(pp, PNG_ALPHA_PNG, PNG_DEFAULT_sRGB);
- * png_set_alpha_mode(pp, PNG_ALPHA_PNG, PNG_GAMMA_MAC);
- * The first call sets both the default and the output gamma values, the
- * second call overrides the output gamma without changing the default. This
- * is easier than achieving the same effect with png_set_gamma. You must use
- * PNG_ALPHA_PNG for the first call - internal checking in png_set_alpha will
- * fire if more than one call to png_set_alpha_mode and png_set_background is
- * made in the same read operation, however multiple calls with PNG_ALPHA_PNG
- * are ignored.

+ * for applications, is an unsigned integer of the form xyyzz corresponding
+ * to the source version x.y.z (leading zeros in y and z). Beta versions
+ * were given the previous public release number plus a letter, until
+ * version 1.0.6j; from then on they were given the upcoming public
+ * release number plus "betaNN" or "rcNN".
+ *
+ * Binary incompatibility exists only when applications make direct access
+ * to the info_ptr or png_ptr members through png.h, and the compiled
+ * application is loaded with a different version of the library.
+ *
+ * DLLNUM will change each time there are forward or backward changes
+ * in binary compatibility (e.g., when a new feature is added).
+ *
+ * See libpng-manual.txt or libpng.3 for more information. The PNG

+ * Y2K compliance in libpng:
+ * =========================
+ *
+ * September 27, 2012
+ *
+ * Since the PNG Development group is an ad-hoc body, we can't make
+ * an official declaration.
+ *
+ * This is your unofficial assurance that libpng from version 0.71 and
+ * upward through 1.5.13 are Y2K compliant. It is my belief that
+ * earlier versions were also Y2K compliant.
+ *
+ * Libpng only has two year fields. One is a 2-byte unsigned integer
+ * that will hold years up to 65535. The other holds the date in text
+ * format, and will hold years up to 9999.
+ *
+ * The integer is
+ * "png_uint_16 year" in png_time_struct.
+ *
+ * The string is
+ * "char time_buffer[29]" in png_struct. This will be no
+ * longer used in libpng-1.6.0 and will be removed from libpng-1.7.0.
+ *
+ * There are seven time-related functions:
+ * png.c: png_convert_to_rfc_1123() in png.c
+ * (formerly png_convert_to_rfc_1152() in error)
+ * png_convert_from_struct_tm() in pngwrite.c, called in pngwrite.c
+ * png_convert_from_time_t() in pngwrite.c
+ * png_get_tIME() in pngget.c
+ * png_handle_tIME() in pngrutil.c, called in pngread.c
+ * png_set_tIME() in pngset.c
+ * png_write_tIME() in pngwutil.c, called in pngwrite.c
+ *
+ * All handle dates properly in a Y2K environment. The
+ * png_convert_from_time_t() function calls gmtime() to convert from system
+ * clock time, which returns (year - 1900), which we properly convert to
+ * the full 4-digit year. There is a possibility that applications using
+ * libpng are not passing 4-digit years into the png_convert_to_rfc_1123()
+ * function, or that they are incorrectly passing only a 2-digit year
+ * instead of "year - 1900" into the png_convert_from_struct_tm() function,
+ * but this is not under our control. The libpng documentation has always
+ * stated that it works with 4-digit years, and the APIs have been
+ * documented as such.
+ *
+ * The tIME chunk itself is also Y2K compliant. It uses a 2-byte unsigned
+ * integer to hold the year, and can hold years as large as 65535.
+ *
+ * zlib, upon which libpng depends, is also Y2K compliant. It contains
+ * no date-related code.

+ *
+ * This has no effect on the way pixels are written into a PNG output
+ * datastream. The color samples in a PNG datastream are never premultiplied
+ * with the alpha samples.
+ *
+ * The default is to return data according to the PNG specification: the alpha
+ * channel is a linear measure of the contribution of the pixel to the
+ * corresponding composited pixel. The gamma encoded color channels must be
+ * scaled according to the contribution and to do this it is necessary to undo
+ * the encoding, scale the color values, perform the composition and reencode
+ * the values. This is the 'PNG' mode.
+ *
+ * The alternative is to 'associate' the alpha with the color information by
+ * storing color channel values that have been scaled by the alpha. The
+ * advantage is that the color channels can be resampled (the image can be
+ * scaled) in this form. The disadvantage is that normal practice is to store
+ * linear, not (gamma) encoded, values and this requires 16-bit channels for
+ * still images rather than the 8-bit channels that are just about sufficient if
+ * gamma encoding is used. In addition all non-transparent pixel values,
+ * including completely opaque ones, must be gamma encoded to produce the final
+ * image. This is the 'STANDARD', 'ASSOCIATED' or 'PREMULTIPLIED' mode (the
+ * latter being the two common names for associated alpha color channels.)
+ *
+ * Since it is not necessary to perform arithmetic on opaque color values so
+ * long as they are not to be resampled and are in the final color space it is
+ * possible to optimize the handling of alpha by storing the opaque pixels in
+ * the PNG format (adjusted for the output color space) while storing partially
+ * opaque pixels in the standard, linear, format. The accuracy required for
+ * standard alpha composition is relatively low, because the pixels are
+ * isolated, therefore typically the accuracy loss in storing 8-bit linear

+ * values are scaled by 100000 in the _fixed version of the API (so 220000 for
+ * sRGB.)
+ *
+ * The inverse of the value is always used to provide a default for the PNG file
+ * encoding if it has no gAMA chunk and if png_set_gamma() has not been called
+ * to override the PNG gamma information.
+ *
+ * When the ALPHA_OPTIMIZED mode is selected the output gamma is used to encode
+ * opaque pixels however pixels with lower alpha values are not encoded,
+ * regardless of the output gamma setting.
+ *
+ * When the standard Porter Duff handling is requested with mode 1 the output
+ * encoding is set to be linear and the output_gamma value is only relevant
+ * as a default for input data that has no gamma information. The linear output
+ * encoding will be overridden if png_set_gamma() is called - the results may be
+ * highly unexpected!
+ *
+ * The following numbers are derived from the sRGB standard and the research
+ * behind it. sRGB is defined to be approximated by a PNG gAMA chunk value of
+ * 0.45455 (1/2.2) for PNG. The value implicitly includes any viewing
+ * correction required to take account of any differences in the color
+ * environment of the original scene and the intended display environment; the
+ * value expresses how to *decode* the image for display, not how the original
+ * data was *encoded*.
+ *
+ * sRGB provides a peg for the PNG standard by defining a viewing environment.
+ * sRGB itself, and earlier TV standards, actually use a more complex transform
+ * (a linear portion then a gamma 2.4 power law) than PNG can express. (PNG is
+ * limited to simple power laws.) By saying that an image for direct display on
+ * an sRGB conformant system should be stored with a gAMA chunk value of 45455
+ * (11.3.3.2 and 11.3.3.5 of the ISO PNG specification) the PNG specification
+ * makes it possible to derive values for other display systems and
+ * environments.
+ *
+ * The Mac value is deduced from the sRGB based on an assumption that the actual
+ * extra viewing correction used in early Mac display systems was implemented as
+ * a power 1.45 lookup table.
+ *
+ * Any system where a programmable lookup table is used or where the behavior of
+ * the final display device characteristics can be changed requires system
+ * specific code to obtain the current characteristic. However this can be
+ * difficult and most PNG gamma correction only requires an approximate value.
+ *
+ * By default, if png_set_alpha_mode() is not called, libpng assumes that all
+ * values are unencoded, linear, values and that the output device also has a
+ * linear characteristic. This is only very rarely correct - it is invariably
+ * better to call png_set_alpha_mode() with PNG_DEFAULT_sRGB than rely on the
+ * default if you don't know what the right answer is!
+ *
+ * The special value PNG_GAMMA_MAC_18 indicates an older Mac system (pre Mac OS
+ * 10.6) which used a correction table to implement a somewhat lower gamma on an
+ * otherwise sRGB system.
+ *
+ * Both these values are reserved (not simple gamma values) in order to allow
+ * more precise correction internally in the future.
+ *
+ * NOTE: the following values can be passed to either the fixed or floating
+ * point APIs, but the floating point API will also accept floating point

+ * This is a somewhat more realistic Jim Blinn inspired approach. PNG files
+ * are assumed to have the sRGB encoding if not marked with a gamma value and
+ * the output is always 16 bits per component. This permits accurate scaling
+ * and processing of the data. If you know that your input PNG files were
+ * generated locally you might need to replace PNG_DEFAULT_sRGB with the
+ * correct value for your system.

+ * If you just need to composite the PNG image onto an existing background
+ * and if you control the code that does this you can use the optimization
+ * setting. In this case you just copy completely opaque pixels to the
+ * output. For pixels that are not completely transparent (you just skip
+ * those) you do the composition math using png_composite or png_composite_16
+ * below then encode the resultant 8-bit or 16-bit values to match the output
+ * encoding.
+ *
+ * Other cases
+ * If neither the PNG nor the standard linear encoding work for you because
+ * of the software or hardware you use then you have a big problem. The PNG
+ * case will probably result in halos around the image. The linear encoding
+ * will probably result in a washed out, too bright, image (it's actually too
+ * contrasty.) Try the ALPHA_OPTIMIZED mode above - this will probably
+ * substantially reduce the halos. Alternatively try:
+ *
+ * png_set_alpha_mode(pp, PNG_ALPHA_BROKEN, PNG_DEFAULT_sRGB);
+ * This option will also reduce the halos, but there will be slight dark
+ * halos round the opaque parts of the image where the background is light.
+ * In the OPTIMIZED mode the halos will be light halos where the background
+ * is dark. Take your pick - the halos are unavoidable unless you can get
+ * your hardware/software fixed! (The OPTIMIZED approach is slightly
+ * faster.)
+ *
+ * When the default gamma of PNG files doesn't match the output gamma.
+ * If you have PNG files with no gamma information png_set_alpha_mode allows
+ * you to provide a default gamma, but it also sets the ouput gamma to the
+ * matching value. If you know your PNG files have a gamma that doesn't
+ * match the output you can take advantage of the fact that
+ * png_set_alpha_mode always sets the output gamma but only sets the PNG
+ * default if it is not already set:
+ *
+ * png_set_alpha_mode(pp, PNG_ALPHA_PNG, PNG_DEFAULT_sRGB);
+ * png_set_alpha_mode(pp, PNG_ALPHA_PNG, PNG_GAMMA_MAC);
+ * The first call sets both the default and the output gamma values, the
+ * second call overrides the output gamma without changing the default. This
+ * is easier than achieving the same effect with png_set_gamma. You must use
+ * PNG_ALPHA_PNG for the first call - internal checking in png_set_alpha will
+ * fire if more than one call to png_set_alpha_mode and png_set_background is
+ * made in the same read operation, however multiple calls with PNG_ALPHA_PNG

-/* Function calling conventions.
- * =============================
- * Normally it is not necessary to specify to the compiler how to call
- * a function - it just does it - however on x86 systems derived from
- * Microsoft and Borland C compilers ('IBM PC', 'DOS', 'Windows' systems
- * and some others) there are multiple ways to call a function and the
- * default can be changed on the compiler command line. For this reason
- * libpng specifies the calling convention of every exported function and
- * every function called via a user supplied function pointer. This is
- * done in this file by defining the following macros:
- *
- * PNGAPI Calling convention for exported functions.
- * PNGCBAPI Calling convention for user provided (callback) functions.
- * PNGCAPI Calling convention used by the ANSI-C library (required
- * for longjmp callbacks and sometimes used internally to
- * specify the calling convention for zlib).
- *
- * These macros should never be overridden. If it is necessary to
- * change calling convention in a private build this can be done
- * by setting PNG_API_RULE (which defaults to 0) to one of the values
- * below to select the correct 'API' variants.
- *
- * PNG_API_RULE=0 Use PNGCAPI - the 'C' calling convention - throughout.
- * This is correct in every known environment.
- * PNG_API_RULE=1 Use the operating system convention for PNGAPI and
- * the 'C' calling convention (from PNGCAPI) for
- * callbacks (PNGCBAPI). This is no longer required
- * in any known environment - if it has to be used
- * please post an explanation of the problem to the
- * libpng mailing list.
- *
- * These cases only differ if the operating system does not use the C
- * calling convention, at present this just means the above cases
- * (x86 DOS/Windows sytems) and, even then, this does not apply to
- * Cygwin running on those systems.
- *
- * Note that the value must be defined in pnglibconf.h so that what
- * the application uses to call the library matches the conventions
- * set when building the library.
- */
-
-/* Symbol export
- * =============
- * When building a shared library it is almost always necessary to tell
- * the compiler which symbols to export. The png.h macro 'PNG_EXPORT'
- * is used to mark the symbols. On some systems these symbols can be
- * extracted at link time and need no special processing by the compiler,
- * on other systems the symbols are flagged by the compiler and just
- * the declaration requires a special tag applied (unfortunately) in a
- * compiler dependent way. Some systems can do either.
- *
- * A small number of older systems also require a symbol from a DLL to
- * be flagged to the program that calls it. This is a problem because
- * we do not know in the header file included by application code that
- * the symbol will come from a shared library, as opposed to a statically
- * linked one. For this reason the application must tell us by setting
- * the magic flag PNG_USE_DLL to turn on the special processing before
- * it includes png.h.
- *
- * Four additional macros are used to make this happen:
- *
- * PNG_IMPEXP The magic (if any) to cause a symbol to be exported from
- * the build or imported if PNG_USE_DLL is set - compiler
- * and system specific.
- *
- * PNG_EXPORT_TYPE(type) A macro that pre or appends PNG_IMPEXP to
- * 'type', compiler specific.
- *
- * PNG_DLL_EXPORT Set to the magic to use during a libpng build to
- * make a symbol exported from the DLL. Not used in the
- * public header files; see pngpriv.h for how it is used
- * in the libpng build.
- *
- * PNG_DLL_IMPORT Set to the magic to force the libpng symbols to come
- * from a DLL - used to define PNG_IMPEXP when
- * PNG_USE_DLL is set.
- */
-
-/* System specific discovery.
- * ==========================
- * This code is used at build time to find PNG_IMPEXP, the API settings
- * and PNG_EXPORT_TYPE(), it may also set a macro to indicate the DLL

- * compiler-specific macros to the values required to change the calling

+ * =============================
+ * Normally it is not necessary to specify to the compiler how to call
+ * a function - it just does it - however on x86 systems derived from
+ * Microsoft and Borland C compilers ('IBM PC', 'DOS', 'Windows' systems
+ * and some others) there are multiple ways to call a function and the
+ * default can be changed on the compiler command line. For this reason
+ * libpng specifies the calling convention of every exported function and
+ * every function called via a user supplied function pointer. This is
+ * done in this file by defining the following macros:
+ *
+ * PNGAPI Calling convention for exported functions.
+ * PNGCBAPI Calling convention for user provided (callback) functions.
+ * PNGCAPI Calling convention used by the ANSI-C library (required
+ * for longjmp callbacks and sometimes used internally to
+ * specify the calling convention for zlib).
+ *
+ * These macros should never be overridden. If it is necessary to
+ * change calling convention in a private build this can be done
+ * by setting PNG_API_RULE (which defaults to 0) to one of the values
+ * below to select the correct 'API' variants.
+ *
+ * PNG_API_RULE=0 Use PNGCAPI - the 'C' calling convention - throughout.
+ * This is correct in every known environment.
+ * PNG_API_RULE=1 Use the operating system convention for PNGAPI and
+ * the 'C' calling convention (from PNGCAPI) for
+ * callbacks (PNGCBAPI). This is no longer required
+ * in any known environment - if it has to be used
+ * please post an explanation of the problem to the
+ * libpng mailing list.
+ *
+ * These cases only differ if the operating system does not use the C

+
+/* Symbol export
+ * =============
+ * When building a shared library it is almost always necessary to tell
+ * the compiler which symbols to export. The png.h macro 'PNG_EXPORT'
+ * is used to mark the symbols. On some systems these symbols can be
+ * extracted at link time and need no special processing by the compiler,
+ * on other systems the symbols are flagged by the compiler and just
+ * the declaration requires a special tag applied (unfortunately) in a
+ * compiler dependent way. Some systems can do either.
+ *
+ * A small number of older systems also require a symbol from a DLL to
+ * be flagged to the program that calls it. This is a problem because
+ * we do not know in the header file included by application code that
+ * the symbol will come from a shared library, as opposed to a statically
+ * linked one. For this reason the application must tell us by setting
+ * the magic flag PNG_USE_DLL to turn on the special processing before
+ * it includes png.h.
+ *
+ * Four additional macros are used to make this happen:
+ *
+ * PNG_IMPEXP The magic (if any) to cause a symbol to be exported from
+ * the build or imported if PNG_USE_DLL is set - compiler
+ * and system specific.
+ *
+ * PNG_EXPORT_TYPE(type) A macro that pre or appends PNG_IMPEXP to
+ * 'type', compiler specific.
+ *
+ * PNG_DLL_EXPORT Set to the magic to use during a libpng build to
+ * make a symbol exported from the DLL. Not used in the
+ * public header files; see pngpriv.h for how it is used
+ * in the libpng build.
+ *
+ * PNG_DLL_IMPORT Set to the magic to force the libpng symbols to come
+ * from a DLL - used to define PNG_IMPEXP when
+ * PNG_USE_DLL is set.
+ */
+
+/* System specific discovery.
+ * ==========================
+ * This code is used at build time to find PNG_IMPEXP, the API settings
+ * and PNG_EXPORT_TYPE(), it may also set a macro to indicate the DLL
+ * import processing is possible. On Windows/x86 systems it also sets
+ * compiler-specific macros to the values required to change the calling

----- IMPORTANT!
-----
----- You should save (press Ctrl+S) this script to:
----- Program Files\Hedgewars\share\hedgewars\Data\Scripts\Multiplayer\Mutant.lua
----- or (on Linux):
----- ~/.hedgewars/Data/Scripts/Multiplayer/Mutant.lua
-----
----- (or wherever scripts like Highlander.lua, Racer.lua are on your system)
-----
----- Also, if you didn't have Mutant script yet, you need to restart Hedgewars for it to find the script file.
-----
-
-
----- GAME RULES
-----
----- Recommended settings:
----- * one hedgehog per team
----- * 'Small' one-island map
-----
----- First one to kill anyone becomes Mutant. Mutant has super-weapons
----- and a lot of health, which however depletes if he doesn't frag fast.
----- Goal of Mutant is to use his weapons to hold his status for as long
----- as he can.
----- Goal of others is to hunt the Mutant down. The one who kills Mutant,
----- becomes Mutant himself.
----- The player with least points (or most deaths) is Bottom Feeder. He
----- can gain points by killing anyone. Other normal players only get points
----- for killing Mutant.
-----
----- Points:
----- +2 for becoming a Mutant
----- +1 to a Mutant for killing anyone
----- +1 to a Bottom Feeder for killing anyone
----- -1 to anyone for a suicide
----- other kills don't give you points.

+---- IMPORTANT!
+----
+---- You should save (press Ctrl+S) this script to:
+---- Program Files\Hedgewars\share\hedgewars\Data\Scripts\Multiplayer\Mutant.lua
+---- or (on Linux):
+---- ~/.hedgewars/Data/Scripts/Multiplayer/Mutant.lua
+----
+---- (or wherever scripts like Highlander.lua, Racer.lua are on your system)
+----
+---- Also, if you didn't have Mutant script yet, you need to restart Hedgewars for it to find the script file.
+----
+
+
+---- GAME RULES
+----
+---- Recommended settings:
+---- * one hedgehog per team
+---- * 'Small' one-island map
+----
+---- First one to kill anyone becomes Mutant. Mutant has super-weapons
+---- and a lot of health, which however depletes if he doesn't frag fast.
+---- Goal of Mutant is to use his weapons to hold his status for as long
+---- as he can.
+---- Goal of others is to hunt the Mutant down. The one who kills Mutant,
+---- becomes Mutant himself.
+---- The player with least points (or most deaths) is Bottom Feeder. He
+---- can gain points by killing anyone. Other normal players only get points
+---- for killing Mutant.
+----
+---- Points:
+---- +2 for becoming a Mutant
+---- +1 to a Mutant for killing anyone
+---- +1 to a Bottom Feeder for killing anyone
+---- -1 to anyone for a suicide
+---- other kills don't give you points.
