%description
RawSpeed…

- is capable of decoding various images in RAW file format.
- is intended to provide the fastest decoding speed possible.
- supports the most common DSLR and similar class brands.
- supplies unmodified RAW data, optionally scaled to 16 bit, or normalized to 0->1 float point data.
- supplies CFA layout for all known cameras.
- provides automatic black level calculation for cameras having such information.
- optionally crops off  “junk” areas of images, containing no valid image information.
- can add support for new cameras by adding definitions to an xml file.
- ~~is extensively crash-tested on broken files~~.
- decodes images from memory, not a file stream. You can use a memory mapped file, but it is rarely faster.
- open source under the LGPL v2 license.
