I have already fixed this in a slightly different way while implementing imformats ().

Still, thank you for the patch.

imread and imfinfo will add '.fmt' parameter to filename and check if the file is there.

updated doc for the added parameter

also added 'Index' as option to select a certain image from a multiple image file (gif, tiff) to be like other numerical packages. So, the changeset also fixes (37369)

(file #27066)

Same answer for any other volunteer-drive project: when it's ready, sooner if you help. If it's easier for you to state that your package doesn't work with Octave than to help us fix Octave, go ahead.

How long might it take to get a response and/or fix on this bug report?  If it is not addressed promptly we may have to drop octave support for the image segmentation package found here:

in Cygwin 1.7.9 (a recent fresh install including Octave-3.4.0 and GraphicMagick-1.3.12)

In MATLAB(7.10.0.499 (R2010a)), when calling imread the following type of call is supported:

#verbatim#
imgpath='images/file';
imread(imgpath,'gif','frames','all');
-verbatim-

This is useful for the case where the image's path does not contain an extension, but it is obtained after an image path variable is set, say with imginfo.  Could this type of imread call be supported for this reason, and also for compatibility with code written in MATLAB?
