Lossless JPEG software, a patch without a license
Dear Legal Gurus,
There is a "semi-official" patch set for the IJG jpeg code:
ftp://ftp.imagemagick.org/pub/ImageMagick/delegates/ljpeg-6b.tar.gz
which adds support for lossless jpeg files.
The archive contains three files:
ljpeg-6b.patch and two copies of a test image, in both lossless
jpeg and ppm format.
There is no Copyright, README, or similar file with a license in.
The patch file does, however, make some changes to the README file
in the jpeg-6b source tree, but these are not concerned with the
License portion of that file.
The implication, as I see it, is that the software is released
under the same license as the main IJG code, but is that a
legally safe assumption?
Can we assume that the patch is released under the same license
as the main ILG code?
I'm quite new to the debian community. I have read the policy
manual and others. I also had a quick scan through the debian-legal
archives. I didn't find an answer, but will happily be corrected
by an appropriate reference.
Regards.
