* gdColorMapLookup() answers the RGB values according to given color map
* Added support of variable resolution
* new filter gdImagePixelate()
* merged improvements that PHP GD team had made to GD Graphics Library
* bugfixes
* Fix valgrind error in gdImageFillTiled
* Add missing custom cmake macros
* Avoid signature buffer copy in gd_gif_c
* Race condition in gdImageStringFTEx
* Reading GIF images is not thread safe (static usage in private functions)
* GIF Local palette is read twice
* GIF, Use local frame dimension when possible instead of the logical screen size
* OpenVMS build support, see VMS/README.VMS for the details
* GIF, do not try to use the global colmap if it does not exist
* gdImageAALine draws axis lines with two pixels width
* TTF usage doesn't work properly on Netware
* gdImageArc CPU usage with large angles
* gdImageFilledRectangle regression fixed when used with reversed edges
* Possible infinite loop in libgd/gd_png.c, flaw found by Xavier Roche
* Fixed segfault when an invalid color index is present in a GIF image data
* Possible integer overflow in gdImageCreateTrueColor
* gdImageCreateXbm can crash if gdImageCreate fails
* 32-bit multiplication overflow vulnerabilities along with a number of similar
issues
* Memory allocation errors that were not checked
* Multiple issues in the GIF loader. Corrupt gif images would cause a segfault
or infinite loop
* Malformed or empty PNG image also may have caused segfaults
* gdImageFillToBorder segfaulted when the color was not opaque (alpha > 0)
* Antialiased lines drawn on an images edge caused a segfault
* gdImageFill segfaulted when used with patterns or invalid arguments
* gdImageFilledEllipse did not respect transparency
"The LZW decoding in the gdImageCreateFromGifPtr function in the Thomas
Boutell graphics draw (GD) library (aka libgd) 2.0.33 allows remote
attackers to cause a denial of service (CPU consumption) via malformed
GIF data that causes an infinite loop."
Patch from Xavier Roche via Ubuntu.
* Windows build uses __stdcall calling convention
* Even more complete freetype version checking
* Binary transparency is now handled correctly in gdImageToPalette
* Correction in gdfontl.h
Changes 2.0.24:
* bgd.dll is now compatible with Visual BASIC
* Even more complete freetype version checking
* Binary transparency is now handled correctly in gdImageToPalette
* horizontal and vertical DPI hints can now be given to the freetype font
renderer via the gdFTStringExtra
* several autoconf problems have been addressed
* the current version of freetype is more precisely detected to prevent
FT_ENCODING_SYMBOL-related errors
* a significant bug in gdNewDynamicCtx was fixed
correcting problem with the built-in gd fonts on Unix
Changes 2.0.18:
introduced a conveniently precompiled DLL for Windows programmers
the default separator of alternative truetype font paths is now
a semicolon rather than a space
minor compilation and packaging problem fixed
Changes 2.0.16:
Adds polar coordinate transformation, text on a circle, thread safety
truetype font output, performance optimizations, correct compilation
with the latest versions of freetype, and many fixes
* Add support for FreeType2 (John Ellson ellson@lucent.com)
[not used in the package right now]
* Add support for finding in fonts in a builtin DEFAULT_FONTPATH, or in a path
from the GDFONTPATH environment variable.
* remove some unused symbols to reduce compiler warnings
* bugfix in size comparisons in gdImageCompare
* REXX now mentioned
* All memory allocation functions are now wrapped within the library; gdFree is
exported and recommended for freeing memory returned by the
gdImage(Something)Ptr family of functions.
