"Insufficient image data" error with a couple of BMPs

[Dinkleberg]

They're probably badly made BMPs, but hey, other programs can process them, why can't Imagemagick?

Code: Select all

I get the same message with IM 6.9.10.14 Q16 Mac OSX. I can open them with Mac Preview, GraphicConverter and Photoshop.

I even tried prefacing with BMP: BMP3: and BMP2:, but that did not work, either.

Thanks for the problem report. We can reproduce it and will have a patch to fix it in GIT master branch @ https://github.com/ImageMagick/ImageMagick later today. The patch will be available in the beta releases of ImageMagick @ https://www.imagemagick.org/download/beta/ by sometime tomorrow.
