%description
jbig2dec is a decoder implementation of the JBIG2 image compression format.
JBIG2 is designed for lossy or lossless encoding of 'bilevel' (1-bit
monochrome) images at moderately high resolution, and in particular scanned
paper documents. In this domain it is very efficient, offering compression
ratios on the order of 100:1.

This package is only needed if you plan to develop or compile applications
which requires the jbig2dec library.
