Description Pavel Shevchuk 2008-04-15 19:23:10 EDT
Spec URL:
RPMs for i386 and x86_64 built in mock:

Epeg is insanely fast at loading large JPEG images and scaling them down to
tiny thumbnails. It's speedup will be proportional to the size difference
between the source image and the output thumbnail size as a count of their

It makes use of libjpeg features of being able to load an image by only
decoding the DCT coefficients needed to reconstruct an image of the size
desired. This gives a massive speedup. If you do not try and access the pixels
in a format other than YUV (or GRAY8 if the source is grascale) then it also
avoids colorspace conversions as well.

RPMLint spits out only W: no-documentation on -devel package because there's no documentation in upstream package. Epeg mostly helper library for higher-lever thumbnailing API - epsilon.
Package works as expected - makes thumbnails of jpegs faster than imagemagick ;)

In the pc file there is -ljpeg, so a dependency for the devel package
to jpeg-devel is missing. Otherwise looks good.
