Mrwtoppm provides a command line utility and a
Gimp plugin for processing RAW image files from
Minolta's DiMAGE 5 and 7 series digital cameras.
The programs decode Minolta's RAW format, perform
Bayer pattern interpolation, and color space
conversion. The programs also perform tone control
and sharpening in CIELab color space. Utilities
for displaying much of the additional data stored
in the RAW file are also included.
