Kodak DCR RAW format - "supported", but actually, no!

[deus_ex_mamiya]

Hi,

The Imagemagick “Formats” webpage says that this format is supported (for reading):
DCR R Kodak Digital Camera Raw Image File

However, the ‘convert’ & ‘display’ commands both spew out error messages, and fail to operate, when I feed them any Kodak .DCR file from my Kodak Proback 645M.
It seems that DCR is not actually supported, at least under my version: I am using ImageMagick-6.4.0, on Suse 11.

Could you please try to fix this? I can supply .dcr files for testing, if this would help.

Thanks,
Ray

What are the error messages?

ImageMagick uses the dcraw program as a "delegate" to read images from several types of digital camera, Kodak being one of them.
I suspect that for some reason dcraw isn't on your system.

Try this command:

• convert dcr:47fb2685.dcr test_dcr.tif

DCR images masquerade as TIFF.

....and dcraw seems to be fine on my system:

ray@baade:~> whereis dcraw
dcraw: /usr/bin/dcraw /usr/bin/X11/dcraw /usr/share/man/man1/dcraw.1.gz

ray@baade:~> which dcraw
/usr/bin/dcraw

ray@baade:~> /usr/bin/dcraw

Thanks, magic! Prefixing the DCR file with dcr:47fb2685.dcr worked!

Case closed...thanks for the help.
