Using the file <http://greenmaw.com/trans-bug.png>, I invoke "convert trans-bug.png trans-bug.mng" but I get a solid black image. (Obviously I'm trying to make an animation, but the behavior is consistent with even only one frame.)
I see this behavior using http://www.imagemagick.org/MagickStudio ... Studio.cgi as well. I tried this with some other transparent PNG files and I didn't see the problem, so perhaps this example will help.
Generated MNG file is all black
Re: Generated MNG file is all black
We can reproduce the problem you posted and have a patch in ImageMagick 6.6.3-1 Beta available by sometime tomorrow. Thanks.
Re: Generated MNG file is all black
Thanks; it's definitely appreciated. Will MagickStudio be updated with this new version as well?
