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.
gd NEWS
=======
What's new in version 2.0.28?
* GIF support has been restored. See gdImageGif, gdImageGifCtx, gdImageGifPtr,
gdImageCreateFromGif, gdImageCreateFromGifCtx, and
gdImageCreateFromGifPtr. These functions are now thread-safe, similar to the PNG
and JPEG manipulation functions.
* The new gdImageCreatePaletteFromTrueColor function is identical to
gdImageTrueColorToPalette, except that it returns a new image rather than
permanently modifying the original.
What's new in version 2.0.27?
* In gd 2.0.26, there was potential for out of bounds fills, and therefore crashes,
in the horizontalLine function used by gdImageFilledPolygon.
Fixed by John Ellson.
* The order of the points returned in the bounding rectangle by gdImageStringFT was
incorrect in version 2.0.26. This has been corrected in version
2.0.27. Thanks to Riccardo Cohen for pointing this out, and to John Ellson for
verifying and fixing it.
What's new in version 2.0.26?
The following enhancements and fixes:
* Drastically faster, less memory-intensive antialiased drawing, thanks to
Pierre-Alain Joye. This code was imported from the PHP "fork" of gd. The
API for antialiased drawing has not changed, however the implementation has been
completely replaced. Antialiased line drawing does not support
widths other than 1, however this did not work properly with the other
implementation of antialiasing either. Support has been included for the
"non-blending color" option introduced by the previous implementation of
antialiased drawing.
* gdlib-config, which has been installed by make install for some time now, has
gained a --features option. This option produces a space-separated
list of optional features with which the gd library was compiled. Typical usage
looks like this:
% gdlib-config --features
GD_XPM GD_JPEG GD_FREETYPE GD_PNG GD_GIF
Other configure scripts can conveniently define preprocessor symbols based on this
list in order to conditionally compile code. For instance, if
GD_PNG is not reported by --features, then gdImagePng is not included in the
library.
Thanks to Lars Hecking and Lincoln Stein for their advice on implementing this
feature. Any blame for the actual implementation is entirely due to
me (TBB).
* Fixes to the behavior of the bounding rectangle returned by gdImageStringFT and
relatives when the string is rotated. See fontwheeltest.c. Thanks
to John Ellson.
* Previously, gdImageStringFT and friends accepted either a full path to a font
file, or the name of a font with no extension, in which case the
GDFONTPATH environment variable and then the compiled-in DEFAULT_FONTPATH was
searched. In addition, a font filename with an extension but no full
path can now be automatically searched for in the same fashion. Thanks to John
Ellson.
* Fixes to freetype antialiased text against a transparent background. See testtr.c.
Thanks to John Ellson.
* Support for named entities like & and hex-coded entities such as 水 in
text strings passed to gdImageStringFT and relatives, adding to
the previous support for decimal-coded entities like Å. These were extracted
from entities.html (from the W3C) via the script entities.tcl,
which is included for the curious and those with other entities they need support
for. Thanks to John Ellson.
* Optimization: gdImageSetPixel no longer calls gdImageAlphaBlend when either the
source or the destination pixel is 100% transparent. Thanks to
John Ellson.
* Optimization: gdImageLine is potentially faster now in the most common cases.
Thanks to John Ellson.
* Documentation of the entities feature of gdImageStringFT.
* autoconf/configure fixes. Thanks to many who pointed out an oversight in handling
libpng flags.
What's new in version 2.0.25?
Owing to an oversight while making changes to better accommodate the use of gd as a
DLL, the extern qualifier was dropped from the declarations of font
pointers in 2.0.24. This has been corrected. Thanks to Richard ("OpenMacNews").
What's new in version 2.0.24?
Windows DLL now uses __stdcall calling convention. Existing applications will require
a recompile, using the new version of gd.h, in order to use this
version of the DLL. However, Visual BASIC and other non-C programmers will now be able
to use the DLL, which is an enormous benefit and justifies the
one-time inconvenience to existing DLL users.
The elaborate #ifdef test for older versions of Freetype without FT_ENCODING_MS_SYMBOL
was needed in a second place also. Thanks to David R. Morrison.
An off-by-one error in gdImageToPalette caused transparency to be applied to the wrong
pixels. Thanks to "Super Pikeman."
What's new in version 2.0.23?
Output dpi specification option added to the gdFTStringExtra structure, thanks to Mark
Shackelford. See gdImageStringFTEx.
What's new in version 2.0.22?
* Win32 DLL users: working with pointers exported by DLLs is difficult and causes
unexpected results. gd 2.0.22 exports new functions for retrieving
the basic gd fonts: gdFontGetTiny(), gdFontGetSmall(), gdFontGetMediumBold(),
gdFontGetLarge(), and gdFontGetHuge(). You may safely assign the return
values from these functions to a local gdFontPtr. Direct use of gdFontLarge, etc.
is strongly deprecated for users of bgd.dll; use these new
functions instead.
* Basic support for loading CMYK-colorspace JPEG images. They are of course
converted to RGB which is a lossy process, however the results do look
quite good and are certainly fine for thumbnails and web previews of DTP work.
* "make" no longer fails on circletexttest if PNG support is missing.
* Small performance improvements to gdImageCopyResampled; larger improvements are
forthcoming.
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.
