Red Hat Bugzilla – Bug 4337
On the version of gd that is included in RawHide...
Last modified: 2008-05-01 11:37:51 EDT
I can see why upgrading to 1.6.* might cause problems for
some people due to the lack of gif file type support in the
library, but is there a reason why gd isn't upgraded to
version 1.5 (which is surely available from somewhere, even
though the author no longer gives it to people)?
The legal issues surrounding the Unisys GIF patent make upgrading
tto gd 1.anything complicated. We'll leave this one alone, thank you.
That seems opposite then, since 1.6 no longer supports GIF files in
order to totally eradicate the problem until the issue is resolved,
yet the version of gd that is in RawHide DOES support GIF files, and
therefor WOULD have "complications"... 1.3 (what RawHide has)
through 1.5 didn't even use LZW compression, and used run length
encoding instead, in an effort to get around the problem anyway
(which would therefor make moving from 1.3 to 1.5 or anything else a
moot issue since all versions have the same problems, the same number
of complications, just newer features). If you really wanted to
avoid this issue entirely, you would upgrade to 1.6. This is my last
argument, simply to clarify issues that I think were misunderstood, I
will not carry this issue further if you still don't wish to upgrade.
the new gd 1.5 has a significantly improved interface that will break
badly the backwards compatibility we are shooting for between our next
release and Red Hat Linux 6.0.
Also this type of changes from its changelog are making me king of
New GD2 format
An improvement over the GD format, the GD2 format uses the zlib
compression library to compress the image in chunks. This results in
file sizes comparable to GIFs, with the ability to access parts of
large images without having to read the entire image into memory.
I understand fighting the compression algorithms by prividing none,
not by implementing "comparable" ones that can be much easily
