* tclconfig/tcl.m4, configure.in, configure: Updated TEA version to 3.6
and regenerated configure script (should fix config errors under Linux).
*** Tagged tkpng-0-9 ***
2008-03-25 00:36 mikek
* generic/tkImgPNG.c: Moved format alpha value to PNGImage structure.
2006-12-15 00:36 mikek
* README, generic/tkImgPNG.c: Added support for writing PNG images
to file (via $image write) or data (via $image data). No line
filtering is currently performed, and writing interlaced images
is not yet supported.
2006-12-14 20:24 mikek
* generic/tkImgPNG.c: inflateEnd/deflateEnd were reversed in PNGCleanup().
2006-12-13 01:08 mikek
* generic/tkImgPNG.c: Made a few more type and cast changes for
consistency and warnings. Added arithmetic overflow check for pitch
in PNGCheckColor().
2006-12-12 00:00 mikek
* generic/tkImgPNG.c: Add integer overflow pre-check for buffer size
in PNGZAlloc() and for pitch and block size in PNGCheckColor().
Remove unnecessary zero-fill of allocated buffer in PNGZAlloc().
2006-12-12 00:00 mikek
* generic/tkImgPNG.c: Standardize on int type for lengths instead
of uLong, for consistency with Tcl_Read() and Tcl_GetByteArrayFromObj(),
etc. Remove mWidth/mHeight, which were redundant: use mBlock.width
and mBlock.height everywhere instead.
2006-12-11 23:50 mikek
* generic/tkImgPNG.c: Added/clarified comments. Refactored
PNGRead() into PNGReadByteArray() and PNGReadBase64, -format
alpha parsing/application into ParseFormat() and ApplyAlpha().
Renamed PNGReadLong() to PNGReadInt32(). Added #defines for some
constants.
2006-12-11 23:23 mikek
* generic/tkImgPNG.c: Removed chunk and line counters, which weren't
used for anything. Renamed some items for clarity and consistency:
dataObj->pObjData, format->pObjFormat, mFile->mChannel, ret->zresult.
Switched K&R style function defs to ANSI style consistently.
2006-12-11 23:12 mikek
* generic/tkImgPNG.c: Renamed PNG_LONG to PNG_INT32. Cast its
arguments to longs to prevent sign extension problems on 64-bit
platforms [1602791].
2006-12-11 18:01 mikek
* generic/tkImgPNG.c: Calculate bit scale once at the end of
PNGCheckColor() instead of every line in DecodeLine(), to avoid
unnecessary overhead.
2006-12-11 01:09 mikek
* generic/tkImgPNG.c: transparency (tRNS chunk) for indexed color
was only allowing the first 1/3 of the palette entries to have
an alpha.
2006-11-27 06:34 mikek
* win/tkpng.sln, win/tkpng.vcproj: Added project and solution files
for MSVC8.
* generic/tkImgPNG.c, generic/tkImgPNGInit.c: Merged changes from
Muonics repository to fix errors/warnings building under MSVC8.
Changed length pointer arguments in calls to Tcl_GetByteArrayFromObj()
calls to point to an intermediary int variable instead of a long.
May fix [1602791].
2006-11-27 05:54 mikek
* generic/tkImgPNG.c: Fixed warning about signedness in Tcl_Read
buffer argument.
* Makefile.in, configure.in, configure, pkgIndex.tcl.in,
tclconfig/tcl.m4: Updated to TEA 3.5, bumped package version to 0.8.
2006-11-27 05:21 mikek
* generic/tkImgPNG.c, generic/tkImgPNGInit.c: Detect build against Tcl/Tk
8.5 or later, where there are different signatures for some of the
Tk_Photo interfaces.
2005-03-26 14:22 mikek
* generic/tkImgPNG.c: Add support for '-format "png -alpha
<0.0..1.0>"' to modify the overall image transparency level upon
image creation.
2005-03-26 14:20 mikek
* generic/tkImgPNGInit.c: Tk 8.3 or later is required to support
alpha.
2005-03-19 21:16 mikek
* README, TODO: [no log message]
2005-03-19 21:02 mikek
* configure, configure.in: Bump version to 0.6.
2005-03-19 21:02 mikek
* generic/tkImgPNG.c: Add base64 decoding support using a lookup
table rather than a monster switch statement (seems a little
faster).
2005-03-19 17:04 mikek
* generic/tkImgPNG.c: Check for needed remaining bytes before
checking for EOF unnecessarily.
2005-03-19 00:09 mikek
* generic/tkImgPNG.c: Optimized unfiltering of scan lines.
2005-03-08 22:27 mikek
* Makefile.in: Disable install-doc target, since there are no docs.
2005-03-08 21:38 mikek
* Makefile.in, README, TODO, configure, configure.in,
license.terms, generic/tkImgPNG.c, generic/tkImgPNGInit.c,
win/makefile.vc: Finished read support with interlacing and all,
but no base64 support yet. Bumped version to 0.5 for first
release.
2005-02-26 19:51 mikek
* Makefile.in, aclocal.m4, configure, configure.in,
generic/tkImgPNG.c, generic/tkImgPNGInit.c, tclconfig/install-sh,
tclconfig/tcl.m4, win/makefile.vc, win/nmakehlp.c, win/rules.vc:
