Error when attempting to output GIF

Software G'MIC
1

G’MIC appears to be looking for GraphicsMagick and ImageMagick.

  1. I have ImageMagick v7 (Windows) which uses magick instead of convert.
  2. G’MIC could be more consistent by choosing to use only one of them. I prefer ImageMagick. :slight_smile: Or it could use whichever happens to be on the system.

From what I’ve read about the ImageMagick 7 release notes, you should still have convert somewhere if you ticked one checkbox during the installation of IM7. Isn’t that the case ?
Please tell me, because depending on your answer, the required changes are probably not the same.

That is true. If I remember correctly, they dropped convert because of a longstanding complaint that it conflicted with some system app(s) with the same name. Now, convert is invoked by magick convert or simply by magick.

gmic -sp lena -sp tiger -o dst.gif,1,0 works now after reinstalling ImageMagick with convert included; so does gmic -sp lena -sp tiger -o dst.gif, which was looking for gm in the error output. That said, I still hope that G’MIC will eventually support magick and provide more GIF options.

Tomorrow, I’ll try to make G’MIC detect IM7’s magick executable instead of convert.
