I'm currently trying to generate a MNG with ImageMagick (Ubuntu 14.04 base version, 6.7.7-10). Basically, I have a set of PNG showing an animated logo, it has lot of alpha in it and since my software is using Qt, I have not a lot of other options to create an animated logo...
If I use animate command with PNGs directly and using dispose option : animate -dispose Background *png. The result is perfect.
However, if I use the convert command (convert -dispose Background *png output.mng), the firsts images are never cleaned, and after 150 images stacking, the result is more than ugly. (little black shadow becomes a huge border...)
I tried several options, but I did not find a proper way to do it.
What I noticed, using identify (identify -verbose test.mng | grep Dispose), that all images, except last, have a Dispose field set at None :
Not sure where to go from it. Any idea?
Edit: Going a bit further. I tried to convert the file in MIFF format, and this time, the images are saved correctly, identify returns Dispose: Background and animate shows it correctly. So it looks to me that there might be an issue there.
Questions and postings pertaining to the usage of ImageMagick regardless of the interface. This includes the command-line utilities, as well as the C and C++ APIs. Usage questions are like "How do I use ImageMagick to create drop shadows?".
