d3261115a8 [libpng15] Imported from libpng-1.5.5rc01.tar 2011-09-15 08:27:01 -05:00

f3f7e14727 [libpng15] Fixed 64-bit compilation errors (gcc). The errors fixed relate 
to conditions where types that are 32 bits in the GCC 32-bit
world (uLong and png_size_t) become 64 bits in the 64-bit
world.  This produces potential truncation errors which the
compiler correctly flags.

9b979b177b [devel] Added new types and internal functions for CIE RGB end point handling 
to pngpriv.h (functions yet to be implemented).

7b9796539d [devel] Prevent unexpected API exports from non-libpng DLLs on Windows. 
The "_DLL" is removed from the test of whether a DLL is being built.

ab63dd0892 [devel] Renamed png_set_chop_16() to png_set_strip_16(). 2011-06-17 20:41:19 -05:00
Glenn Randers-Pehrson
5f0b9276ec [devel] Made PNG_READ_16_TO_8_ACCURATE_SCALE configurable again. 
If this is not enabled, png_set_strip_16() and png_do_scale_16_to_8()
aren't built.

6a1dc2329a [devel] Removed string/memory macros that are no longer used 
and are not necessarily fully supportable, particularly png_strncpy and
png_snprintf.

2d3fc1ca3b [devel] Moved macro definitions for PNG_HAVE_IHDR, PNG_HAVE_PLTE, and 
PNG_AFTER_IDAT from pngpriv.h to png.h because they must be visible to
applications that call png_set_unknown_chunks().

f70c7d02e9 [devel] Added named value and 'flag' gamma support to png_set_gamma. Made a 
minor change from the previous (unreleased) ABI/API to hide the exact value
used for Macs - it's not a good idea to embed this in the ABI!

d273ad2d0f [devel] Implementation of premultiplied alpha support: png_set_alpha_mode 
(libpng-manual.txt still to be updated, see png.h for documentation.)

c5bef946b1 [devel] IDAT compression failed if preceded by a compressed text chunk 
This was because the attempt to reset the zlib stream in png_write_IDAT
happened after the first IDAT chunk had been deflated - much too late.
In this change internal functions are added to claim/release the z_stream
and, hopefully, make the code more robust.  Also deflateEnd checking is
added - previously libpng would ignore an error at the end of the stream.

88b77cc6f3 [devel] Remove png_snprintf, add formatted warning messages. 
This change adds internal APIs to allow png_warning messages to have parameters
 without requiring the host OS to implelment snprintf.  As a side effect the
 dependency of the RFC1132 code on stdio is removed and PNG_NO_WARNINGS does
 actually work now.

b3b7168077 [devel] Added appropriate feature test macros (_POSIX_SOURCE, _ISOC99_SOURCE) 
to ensure libpng sees the correct API.

4a12f4a22a [devel] Cleanup of conditional compilation code and of background/gamma 
handling. Internal changes only except for a new option to avoid compiling
in the png_build_grayscale_palette API (which is not used at all internally.)
The main change is to move the transform tests (READ_TRANSFORMS,
WRITE_TRANSFORMS) up one level to the caller of the APIs.
