Re: Recognize broken profile

Thanks for clarification.
We already use exiftool and can inspect a profile with this tool as well. Generally, the color space of the image (determined by identify) hast to match the color space of the profile. Checking this will avoid psychedelic colors.

Re: Alpha channel gets removed from grayscale image with IM 7.x

Thanks for reply. Leaving out [0] everywhere solves the issue.
Can anyone tell me why this worked in previous IM Versions? Is it a general recommendation to leave out [0]?

Re: Alpha channel gets removed from grayscale image with IM 7.x

Thanks, using your recommendations, I do get a transparent image. Next step after conversion is to draw a shadow. With ImageMagick 6 and the cited command, the shadow was drawn around the object. Now, the shadow is drawn at the border of the canvas. This seems to be because the apha channel is no ...

Re: Alpha channel gets removed from grayscale image with IM 7.x

To your last comment: You are absolutely right, the unsharp mask is worth nothing.
The command line given is the result of a longer script that generates it - with some overhead.

Alpha channel gets removed from grayscale image with IM 7.x

I recently needed to upgrade from IM 6.7 to IM 7.x and ran into trouble with grayscale images. Precisely, I have a PSD file with alpha channel and clipping path which converted well with the existing generic script. But now, using the very same script, the alpha channel is removed. Command line ...
