cr2-raw format not properly detected

[_maekke_]

Hello,

when trying to convert/identify cr2-raw files from my canon camera, it fails do detect them correctly.

Code: Select all

$ convert img_9812.cr2 test.jpg
convert: incorrect count for field "BitsPerSample" (3, expecting 1); tag trimmed. `img_9812.cr2'.
convert: img_9812.cr2: unknown field with tag 40961 (0xa001) encountered. `TIFFReadCustomDirectory'.
convert: img_9812.cr2: unknown field with tag 40965 (0xa005) encountered. `TIFFReadCustomDirectory'.
convert: incorrect count for field "BitsPerSample" (3, expecting 1); tag trimmed. `img_9812.cr2'.
convert: compression not supported `img_9812.cr2'.
convert: missing an image filename `test.jpg'.

this happens with imagemagick-6.4.4-1 (and certainly 6.4.3-5, too).
last known working version is 6.4.0-6.

Try this command:

• convert cr2:img_9812.cr2 test.jpg

Try this command:

• convert cr2:img_9812.cr2 test.jpg

Code: Select all

$ convert cr2:img_9812.cr2 test.jpg
$ echo $?
0

works without problems.

Hi,

this problem seems to be related to

viewtopic.php?f=3&t=12188

Adding the cr2: prefix is fine for a single, manual convert operation. But for an automatic, script-based image-processing application this is not a solution. And in previous versions, IM had no problem autodetecting the cr2 or nef image types.
