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, which is deprecated, - * 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 is no longer used - * in libpng-1.6.x and will be removed from libpng-1.7.0. - * - * There are seven time-related functions: - * png.c: png_convert_to_rfc_1123_buffer() in png.c - * (formerly png_convert_to_rfc_1123() prior to libpng-1.5.x and - * png_convert_to_rfc_1152() in error prior to libpng-0.98) - * 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 libpng applications - * are not passing 4-digit years into the png_convert_to_rfc_1123_buffer() - * 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. - * - * Glenn Randers-Pehrson - * libpng maintainer - * PNG Development Group - */ - -#ifndef PNG_H -#define PNG_H - -/* This is not the place to learn how to use libpng.
