unable to convert raw images

I installed ImageMagick6.9.1 in my fedora 18 together with ufraw-0.22
(from source)

everything installed ok.

But when I run

convert -verbose /home/jenny/IMG_5955.CR2 /home/jenny/IMG_5955.png

I get

Code: Select all

"ufraw-batch" --silent --create-id=also --out-type=png --out-depth=16 "--output=/tmp/magick-12526Vo30i1lVwHJm.png" "/tmp/magick-12526PuarTWMsIHtX"
"ufraw-batch" --silent --create-id=also --out-type=png --out-depth=16 "--output=/tmp/magick-12526MrA2ryQdoFgx.png" "/tmp/magick-12526I6V2pqOfMG36"
convert: delegate failed `"ufraw-batch" --silent --create-id=also --out-type=png --out-depth=16 "--output=%u.png" "%i"' @ error/delegate.c/InvokeDelegate/1332.
convert: unable to open image `/tmp/magick-12526Vo30i1lVwHJm.ppm': No such file or directory @ error/blob.c/OpenBlob/2697.
convert: no images defined `/home/jenny/IMG_5955.jpg' @ error/convert.c/ConvertImageCommand/3212.

I am at a loss.

I am not a raw expert, but I believe you need to specify the dimensions of the raw image. See http://www.imagemagick.org/Usage/formats/#crw

I suppose IMG_5955.CR2 is a raw camera file, convertible to PNG or whatever by ufraw-batch. Its internal metadata gives width, height etc, so they don't need to be specified in the command.

"delegate failed", so is ufraw-batch installed? Try running it from the command line.

Yes you are correct that ImageMagick is calling ufraw-batch to do the conversion.
And yes ufraw-batch is installed and works.

Then I suppose this command works?

Code: Select all

"ufraw-batch" --silent --create-id=also --out-type=png --out-depth=16 "--output=/home/jenny/IMG_5955.png" "/home/jenny/IMG_5955.CR2"
If so, it may be a permissions problem, but I'm only guessing. Do you have read/write access to /tmp? Is it full?

Your command works for me on Windows command line but it is calling dcraw. Does the Windows Imagemagick use dcraw rather than ufraw?

No need to add any dimensions etc. and this was with version 6.9.0
