=============

CR2 DataType is a picture datatype for displaying "Canon CR2 RAW" images under
AmigaOS 3.0 or higher.

Canon CR2 is a TIFF based file format used by many Canon digital cameras for RAW
photos.
The file name extension is ".CR2".
It contains different versions of the same image (details from Canon EOS 400D):
1) JPEG Preview Image   1936 x 1288 x 24-bit
2) JPEG Thumbnail Image  160 x  120 x 24-bit
3) RGB Preview Image     384 x  256 x 24-bit
4) RAW Image            3888 x 2592 x 24-bit

A new version supporting images of type "4) RAW Image" and an utility are being
evaluated
and their future is depending on people feedback.
