ff2jpgconvert farbfeld to JPG

ff2jpg [-b colour] [-o] [-q quality]

ff2jpg reads a farbfeld(5) image from stdin, converts it to JPG (8-bit RGB) and writes the result to stdout.

In case of an error ff2jpg writes a diagnostic message to stderr.

colour
Blend the transparent colours with colour specified as rgb, rrggbb or rrrrggggbbbb. The default is fff.
Optimize the Huffman table, which reduces the file size but takes longer.
quality
Set the output quality ranging from 0 to 100. The default is 85.

0
Image processed successfully.
