Hello,

We have compiled a new 6.8 version of IM (in an attempt to upgrade from Ubuntu's packaged 6.7.7-10.

Our command using +profile "*" just hangs. Removing +profile "*" resolves the hangup, and adding -strip instead seems achieve the same result.

Example:
'/opt/imagemagick-6.8/bin/convert' 'in.jpg'[0] +matte -flatten -quality 90 +matte +profile "*" -colorspace sRGB -resize 850x850">" 'out.jpg'

What I'm wondering is whether the API has intentionally changed in regard to +profile or whether this is a bug, or even possibly a compilation error.

Thank you,
Tom Gleason

/opt/imagemagick-6.8/bin/convert' 'in.jpg'[0] +matte -flatten -quality 90 +matte +profile "*" -colorspace sRGB -resize 850x850">"

JPG does not support transparency nor multilayer/multiframe/multiplage, so +matte and -flatten is likely doing nothing.

I am on IM 6.8.9.5 Q16 Mac OSX

This indeed hangs. I will report on bugs forum.

Thanks. We know that +matte and -flatten are pointless here, but I included them because we do in this command to support multiple formats, in case they were factors.

Is -strip equivalent for us at this point? It seems to work the same, but I'm not 100% sure.

From the command-line-options page:

strip the image of any profiles or comments.

It also removes any EXIF data if there is any.
