Libpng 1.0.12beta1 - May 14, 2001
Libpng 1.0.13 - April 15, 2002
This is a public release of libpng, intended for use in production codes.
Changes since the last public release (1.0.11):
Changes since the last public release (1.2.1):
Test for Windows platform in pngconf.h when including malloc.h (Emmanuel Blot)
Updated makefile.cygwin and handling of Cygwin's ALL_STATIC in pngconf.h
Added some never-to-be-executed code in pnggccrd.c to quiet compiler warnings.
Bumped DLLNUM to 2.
Added a check for attempts to read or write PLTE in grayscale PNG datastreams.
Eliminated the png_error about apps using png_read|write_init(). Instead,
libpng will reallocate the png_struct and info_struct if they are too small.
This achieves future binary compatibility for old applications written for
libpng-0.88 and earlier.
Modified png_create_struct so it passes user mem_ptr to user memory allocator.
Fixed a bug with reading the length of iCCP profiles (Larry Reeves).
Revised makefile.linux, makefile.gcmmx, and others to generate
libpng.a, libpngNN.so, libpng.so.NN, and libpngNN/png.h
Revised makefile.darwin to remove "-undefined suppress" option.
Added checks for gamma and chromaticity values over 21474.83, which exceed
the limit for PNG unsigned 32-bit integers when encoded.
Revised calls to png_create_read_struct() and png_create_write_struct()
for simpler debugging.
Revised png_zalloc() so zlib handles errors (uses PNG_FLAG_MALLOC_NULL_MEM_OK)
Check chunk_length and idat_size for invalid (over PNG_MAX_UINT) lengths.
Check for invalid image dimensions in png_get_IHDR.
Added install-shared and install-static targets to all makefiles that make
shared libraries.
Always do gamma compensation when image is partially transparent.
Modified shared-library makefiles to install pkgconfig/libpngNN.pc.
Export (with PNGAPI) png_zalloc, png_zfree, and png_handle_as_unknown
Removed unused png_write_destroy_info prototype from png.h
Eliminated incorrect use of width_mmx from pnggccrd.c in pixel_bytes == 8 case
Stopped a double free of palette, hist, and trans when not using free_me.
Added makefile.32sunu for Sun Ultra 32 and makefile.64sunu for Sun Ultra 64.
Compute background.gray and background_1.gray even when color_type is RGB
in case image gets reduced to gray later (Jason Summers).
Added PNG_1_0_X macro which can be used to build a 1.0.x-compatible library.
Added missing PNGAPI to several function definitions.
Check for invalid bit_depth or color_type in png_get_IHDR(), and
check for missing PLTE or IHDR in png_push_read_chunk() (Matthias Clasen).
Revised iTXt support to accept NULL for lang and lang_key.
Compute gamma for color components of background even when color_type is gray.
Revised makefiles to put png.h and pngconf.h only in $prefix/include/libpngNN
Revised makefiles to make symlink to libpng.so.NN in addition to libpngNN.so
Prevent png_zalloc() from trying to memset memory that it failed to acquire.
Add typecasts of PNG_MAX_UINT in pngset_cHRM_fixed() (Matt Holgate).
Ensure that the right function (user or default) is used to free the
png_struct after an error in png_create_read_struct_2().
Save the ebx register in pnggccrd.c (Sami Farin)
Add "mem_ptr = png_ptr->mem_ptr" in png_destroy_write_struct() (Paul Gardner).
Updated makefiles to put headers in include/libpng and remove old include/*.h.
Revised description of png_set_filter() in libpng.3/libpng.txt.
Revised makefile.netbsd and added makefile.neNNbsd and makefile.freebsd

Y2K compliance in libpng:

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 1.0.12beta1 are Y2K compliant. It is my belief that earlier
upward through 1.0.13 are Y2K compliant. It is my belief that earlier
versions were also Y2K compliant.

See the main README file for basic instructions on compiling and running
the programs. See http://www.cdrom.com/pub/png/pngbook.html for further
information and links to the source code, and Chapters 13-15 of the book
for detailed discussion of the three programs.
Since the two viewers, rpng and rpng2, are both designed to write infor-
mation to the console (i.e., a DOS-window command line) while displaying
the image in a graphical window--and since I haven't yet figured out how
to do that under Windows--here are the usage screens for the two programs:
rpng-win 1.02 of 19 March 2000: Simple PNG Viewer for Windows
Compiled with libpng 1.0.5; using libpng 1.0.5.
Compiled with zlib 1.1.3; using zlib 1.1.3.
Usage: rpng-win [-gamma exp] [-bgcolor bg] file.png
exp transfer-function exponent (``gamma'') of the display
system in floating-point format (e.g., ``2.2''); equal
to the product of the lookup-table exponent (varies)
and the CRT exponent (usually 2.2); must be positive
bg desired background color in 7-character hex RGB format
(e.g., ``#ff7f00'' for orange: same as HTML colors);
used with transparent images
Press Q, Esc or mouse button 1 after image is displayed to quit.
rpng2-win 1.04 of 19 March 2000: Progressive PNG Viewer for Windows
Compiled with libpng 1.0.5; using libpng 1.0.5.
Compiled with zlib 1.1.3; using zlib 1.1.3.
Usage: rpng2-win [-gamma exp] [-bgcolor bg | -bgpat pat] [-timing] file.png
exp transfer-function exponent (``gamma'') of the display
system in floating-point format (e.g., ``2.2''); equal
to the product of the lookup-table exponent (varies)
and the CRT exponent (usually 2.2); must be positive
bg desired background color in 7-character hex RGB format
(e.g., ``#ff7f00'' for orange: same as HTML colors);
used with transparent images; overrides -bgpat
pat desired background pattern number (1-16); used with
transparent images; overrides -bgcolor
-timing enables delay for every block read, to simulate modem
download of image (~36 Kbps)
Press Q, Esc or mouse button 1 after image is displayed to quit.
The usage screen for the third (non-windowed) program, wpng, can be seen
simply by invoking it without any parameters (``wpng'').
