Hi
A new version of 'gd/libgd2/libgd-devel' has been uploaded to a server near you.
DESCRIPTION:
============
A graphics library for fast image creation
CYGWIN NEWS:
============
* Update to latest upstream release.
* Cygwin specific patch for GIF conversion utilities is not needed
anymore, as these files are included upstream again
gd NEWS
=======
What's new in version 2.0.33?
Version 2.0.33 restores compatibility with older releases of Freetype 2.x in
addition to the latest release. Thanks to John Ellson and the graphviz project.
What's new in version 2.0.32?
Version 2.0.32 restores correct detection of Unicode character sets for freetype
fonts, which repairs a bug that prevented umlauts from displaying properly.
Thanks to John Ellson and the graphviz project. Also, version 2.0.32 builds
all test programs smoothly in the absence of libpng.
What's new in version 2.0.31?
A minor type naming conflict prevented bgd.dll from compiling, and it was left
out of the distribution as a result. This has been corrected.
What's new in version 2.0.30?
2.0.29 did not compile correctly when freetype was not available. This has been
corrected. Thanks to Alessandro Ranellucci.
What's new in version 2.0.29?
* A 32-bit multiplication overflow vulnerability reported on the Bugtraq
mailing list has been corrected, along with a number of similar issues.
These bugs come into play only when attempting to deal with images with
extremely large dimensions. The relevant functions now fail gracefully
when such extreme parameters are specified. The code in question is also
correct for systems with larger bit depths. Thanks to Phil Knirsch, Alan
Cox and infamous41md. Since exploits are theoretically possible, upgrading
is recommended.
* Support for the fontconfig library, when available. When fontconfig is
available and gdFTUseFontConfig(1) has been invoked or the gdFTEX_FONTCONFIG
flag has been set for a particular call, fontconfig patterns can be used
to fetch the best available font. For instance, "arial:bold:italic" does
the right thing (or as close as the available fonts permit). Also, standard
PostScript font names can be mapped to an appropriate font by gdImageStringFTEx
and relatives. When fontconfig is available gdlib-config --features will
list the GD_FONTCONFIG feature. For more information about fontconfig,
see the fontconfig pages.
The actual resolved font filename can be returned in the gdFTStringExtra
structure as the fontpath element if the gdFTEX_RETURNFONTPATHNAME flag
is set. Also, a vector of character position advances can be retrieved
if gdFTEX_XSHOW is set in the flags element. .afm files (font metrics)
are now used to adjust size calculations when available. When fontconfig
is not available, gd falls back to its usual behavior and requires a
specific font file name. One can still fetch fonts by filename when
gdFTUseFontConfig(1) is in effect, by setting the gdFTEX_FONTPATHNAME flag
in the flag element of the gdFTStringExtra structure. Thanks to Dag Lem
and John Ellson.
* Additional freetype fixes: fixed width fonts are now the right size,
horizontal advance calculations now better match the PostScript equivalent,
and various compiler warning fixes. Also, a fix to the encoding table
selection in the was made, addressing a problem with latin1 font encodings.
Thanks to Dag Lem and John Ellson.
* Improved tolerance when reading JPEG files containing some garbage as well
as valid image data.
* Easier compilation on Windows: no errno.h in gd_gd2.c.
* Support for creating optimized GIF animations has been added by Jaakko
Hyvätti. See gdImageGifAnimAdd, gdImageGifAnimAddCtx, gdImageGifAnimAddPtr,
gdImageGifAnimBegin, gdImageGifAnimBeginCtx, gdImageGifAnimBeginPtr,
gdImageGifAnimEnd, gdImageGifAnimEndCtx, and gdImageGifAnimEndPtr.
* gdImageOpenPolygon has been added to allow consecutive line segments to be
drawn without connecting the end points to form a closed polygon. Thanks to
Jaakko Hyvätti.
* Better alpha channel blending when the destination color contains an alpha
channel. Also, quicker handling of the most common cases. Thanks to Frank
Warmerdam.
INSTALLATION:
=============
To update your installation, click on the "Install Cygwin now" link on
the http://cygwin.com/ web page. This downloads setup.exe to your
system. Save it and run setup, answer the questions and pick up
the above mentioned package from the 'Libs' category.
DOWNLOAD:
=========
Note that downloads from sources.redhat.com (aka cygwin.com) aren't
allowed due to bandwidth limitations. This means that you will need
to find a mirror which has this update.
These mirrors already got the package, the others will probably have
the latest version of this package fairly soon:
In the US
ftp://mirrors.rcn.net/pub/sourceware/cygwin/
has reliable high bandwidth connections.
QUESTIONS:
==========
If you want to make a point or ask a question the Cygwin mailing
list is the appropriate place.
