IM 6.7.1.0 Q16 Mac OSX Tiger

I am getting an error message when trying to do equal size crop regions. (http://www.imagemagick.org/Usage/crop/#crop_equal)


convert rose: -crop '20x20@' +repage rose_%d.png
convert: geometry does not contain image `ROSE' @ warning/transform.c/CropImage/622.

We can reproduce the problem you posted and have a fix in ImageMagick-6.7.1-1 Beta available by sometime tomorrow. Thanks.

This does not seem to be fixed in IM 6.7.1.1 Q16 Mac OSX Tiger:


convert -size 40x40 xc:red -crop 20x20@ +repage red_%d.png


should produce 4 images, but I get 360 images

Am I doing something wrong with my command?



Likewise:


convert rose: -crop '20x20@' +repage rose_%d.png


produces 379 images.

We'll have a patch by sometime tomorrow. In the meantime read http://www.imagemagick.org/Usage/crop/#crop_equal. Its possible Anthony changed the semantics of the area crop. You want -crop 2x2@ to produce 4 images.

You are correct. My mistake on the syntax.

So there is no error currently in IM 6.7.1.1.
