# These two allow automatic lossless rotation of JPEG images from a digital
# camera which have orientation markings in the EXIF data. After rotation
# the orientation markings are reset to avoid duplicate rotation when
# applying these programs again.

%description
This package contains a library of functions for manipulating JPEG images.
It is a high-speed, libjpeg-compatible version for x86 and x86-64
processors which uses SIMD instructions (MMX, SSE2, etc.) to accelerate
baseline JPEG compression and decompression. It is generally 2-4x as fast
as the unmodified version of libjpeg, all else being equal.

%description -n jpeg-progs
This package contains simple client programs for accessing the
libjpeg functions.  The library client programs include cjpeg, djpeg,
jpegtran, rdjpgcom, wrjpgcom and jpegexiforient, coupled with the script
exifautotran. Cjpeg compresses an image file into JPEG format. Djpeg
decompresses a JPEG file into a regular image file. Jpegtran can perform
various useful transformations on JPEG files: it can make lossless
cropping of JPEG files and lossless pasting of one JPEG into another
(dropping). Rdjpgcom displays any text comments included in a JPEG file.
Wrjpgcom inserts text comments into a JPEG file. Jpegexiforient allow
automatic lossless rotation of JPEG images from a digital camera which
have orientation markings in the EXIF data.
