Don't let the 155821806d5e7f356e8fa4b058a389a808ea183019Torne (Richard Coles)fact that it's the first release fool you. The libpng library has been in 165821806d5e7f356e8fa4b058a389a808ea183019Torne (Richard Coles)extensive use and testing since mid-1995. By late 1997 it had 175821806d5e7f356e8fa4b058a389a808ea183019Torne (Richard Coles)finally gotten to the stage where there hadn't been significant 185821806d5e7f356e8fa4b058a389a808ea183019Torne (Richard Coles)changes to the API in some time, and people have a bad feeling about 195821806d5e7f356e8fa4b058a389a808ea183019Torne (Richard Coles)libraries with versions < 1.0. Version 1.0.0 was released in 205821806d5e7f356e8fa4b058a389a808ea183019Torne (Richard Coles)March 1998. 215821806d5e7f356e8fa4b058a389a808ea183019Torne (Richard Coles) 225821806d5e7f356e8fa4b058a389a808ea183019Torne (Richard Coles)**** 235821806d5e7f356e8fa4b058a389a808ea183019Torne (Richard Coles)Note that some of the changes to the png_info structure render this 245821806d5e7f356e8fa4b058a389a808ea183019Torne (Richard Coles)version of the library binary incompatible with libpng-0.89 or 255821806d5e7f356e8fa4b058a389a808ea183019Torne (Richard Coles)earlier versions if you are using a shared library. The type of the 265821806d5e7f356e8fa4b058a389a808ea183019Torne (Richard Coles)"filler" parameter for png_set_filler() has changed from png_byte to 275821806d5e7f356e8fa4b058a389a808ea183019Torne (Richard Coles)png_uint_32, which will affect shared-library applications that use 285821806d5e7f356e8fa4b058a389a808ea183019Torne (Richard Coles)this function. 295821806d5e7f356e8fa4b058a389a808ea183019Torne (Richard Coles) 305821806d5e7f356e8fa4b058a389a808ea183019Torne (Richard Coles)To avoid problems with changes to the internals of png_info_struct, 315821806d5e7f356e8fa4b058a389a808ea183019Torne (Richard Coles)new APIs have been made available in 0.95 to avoid direct application 325821806d5e7f356e8fa4b058a389a808ea183019Torne (Richard Coles)access to info_ptr. These functions are the png_set_<chunk> and 335821806d5e7f356e8fa4b058a389a808ea183019Torne (Richard Coles)png_get_<chunk> functions. These functions should be used when 345821806d5e7f356e8fa4b058a389a808ea183019Torne (Richard Coles)accessing/storing the info_struct data, rather than manipulating it 355821806d5e7f356e8fa4b058a389a808ea183019Torne (Richard Coles)directly, to avoid such problems in the future. 365821806d5e7f356e8fa4b058a389a808ea183019Torne (Richard Coles) 375821806d5e7f356e8fa4b058a389a808ea183019Torne (Richard Coles)It is important to note that the APIs do not make current programs 385821806d5e7f356e8fa4b058a389a808ea183019Torne (Richard Coles)that access the info struct directly incompatible with the new 395821806d5e7f356e8fa4b058a389a808ea183019Torne (Richard Coles)library. However, it is strongly suggested that new programs use 405821806d5e7f356e8fa4b058a389a808ea183019Torne (Richard Coles)the new APIs (as shown in example.c and pngtest.c), and older programs 415821806d5e7f356e8fa4b058a389a808ea183019Torne (Richard Coles)be converted to the new format, to facilitate upgrades in the future. 425821806d5e7f356e8fa4b058a389a808ea183019Torne (Richard Coles)**** 435821806d5e7f356e8fa4b058a389a808ea183019Torne (Richard Coles) 445821806d5e7f356e8fa4b058a389a808ea183019Torne (Richard Coles)Additions since 0.90 include the ability to compile libpng as a 455821806d5e7f356e8fa4b058a389a808ea183019Torne (Richard Coles)Windows DLL, and new APIs for accessing data in the info struct. 465821806d5e7f356e8fa4b058a389a808ea183019Torne (Richard Coles)Experimental functions include the ability to set weighting and cost 475821806d5e7f356e8fa4b058a389a808ea183019Torne (Richard Coles)factors for row filter selection, direct reads of integers from buffers 485821806d5e7f356e8fa4b058a389a808ea183019Torne (Richard Coles)on big-endian processors that support misaligned data access, faster 495821806d5e7f356e8fa4b058a389a808ea183019Torne (Richard Coles)methods of doing alpha composition, and more accurate 16->8 bit color 505821806d5e7f356e8fa4b058a389a808ea183019Torne (Richard Coles)conversion. 515821806d5e7f356e8fa4b058a389a808ea183019Torne (Richard Coles) 525821806d5e7f356e8fa4b058a389a808ea183019Torne (Richard Coles)The additions since 0.89 include the ability to read from a PNG stream 535821806d5e7f356e8fa4b058a389a808ea183019Torne (Richard Coles)which has had some (or all) of the signature bytes read by the calling 545821806d5e7f356e8fa4b058a389a808ea183019Torne (Richard Coles)application. This also allows the reading of embedded PNG streams that 555821806d5e7f356e8fa4b058a389a808ea183019Torne (Richard Coles)do not have the PNG file signature. As well, it is now possible to set 565821806d5e7f356e8fa4b058a389a808ea183019Torne (Richard Coles)the library action on the detection of chunk CRC errors. It is possible 575821806d5e7f356e8fa4b058a389a808ea183019Torne (Richard Coles)to set different actions based on whether the CRC error occurred in a 585821806d5e7f356e8fa4b058a389a808ea183019Torne (Richard Coles)critical or an ancillary chunk. 595821806d5e7f356e8fa4b058a389a808ea183019Torne (Richard Coles) 605821806d5e7f356e8fa4b058a389a808ea183019Torne (Richard Coles)The changes made to the library, and bugs fixed are based on discussions 615821806d5e7f356e8fa4b058a389a808ea183019Torne (Richard Coles)on the png-mng-implement mailing list and not on material submitted 625821806d5e7f356e8fa4b058a389a808ea183019Torne (Richard Coles)privately to Guy, Andreas, or Glenn. They will forward any good 635821806d5e7f356e8fa4b058a389a808ea183019Torne (Richard Coles)suggestions to the list. 645821806d5e7f356e8fa4b058a389a808ea183019Torne (Richard Coles) 655821806d5e7f356e8fa4b058a389a808ea183019Torne (Richard Coles)For a detailed description on using libpng, read libpng.txt. For 665821806d5e7f356e8fa4b058a389a808ea183019Torne (Richard Coles)examples of libpng in a program, see example.c and pngtest.c. For usage 675821806d5e7f356e8fa4b058a389a808ea183019Torne (Richard Coles)information and restrictions (what little they are) on libpng, see 685821806d5e7f356e8fa4b058a389a808ea183019Torne (Richard Coles)png.h. For a description on using zlib (the compression library used by 695821806d5e7f356e8fa4b058a389a808ea183019Torne (Richard Coles)libpng) and zlib's restrictions, see zlib.h 705821806d5e7f356e8fa4b058a389a808ea183019Torne (Richard Coles) 715821806d5e7f356e8fa4b058a389a808ea183019Torne (Richard Coles)I have included a general makefile, as well as several machine and 725821806d5e7f356e8fa4b058a389a808ea183019Torne (Richard Coles)compiler specific ones, but you may have to modify one for your own needs. 735821806d5e7f356e8fa4b058a389a808ea183019Torne (Richard Coles) 745821806d5e7f356e8fa4b058a389a808ea183019Torne (Richard Coles)You should use zlib 1.0.4 or later to run this, but it MAY work with 755821806d5e7f356e8fa4b058a389a808ea183019Torne (Richard Coles)versions as old as zlib 0.95. Even so, there are bugs in older zlib 765821806d5e7f356e8fa4b058a389a808ea183019Torne (Richard Coles)versions which can cause the output of invalid compression streams for 775821806d5e7f356e8fa4b058a389a808ea183019Torne (Richard Coles)some images. You will definitely need zlib 1.0.4 or later if you are 785821806d5e7f356e8fa4b058a389a808ea183019Torne (Richard Coles)taking advantage of the MS-DOS "far" structure allocation for the small 795821806d5e7f356e8fa4b058a389a808ea183019Torne (Richard Coles)and medium memory models. You should also note that zlib is a 805821806d5e7f356e8fa4b058a389a808ea183019Torne (Richard Coles)compression library that is useful for more things than just PNG files. 815821806d5e7f356e8fa4b058a389a808ea183019Torne (Richard Coles)You can use zlib as a drop-in replacement for fread() and fwrite() if 825821806d5e7f356e8fa4b058a389a808ea183019Torne (Richard Coles)you are so inclined. 835821806d5e7f356e8fa4b058a389a808ea183019Torne (Richard Coles) 845821806d5e7f356e8fa4b058a389a808ea183019Torne (Richard Coles)zlib should be available at the same place that libpng is, or at 855821806d5e7f356e8fa4b058a389a808ea183019Torne (Richard Coles)ftp://ftp.simplesystems.org/pub/png/src/ 865821806d5e7f356e8fa4b058a389a808ea183019Torne (Richard Coles) 875821806d5e7f356e8fa4b058a389a808ea183019Torne (Richard Coles)You may also want a copy of the PNG specification.
