I’ve tried to use ImageMagick to create .ico files for Open Yahtzee, out of PNGs of various sizes. The command as it should have been:
convert openyahtzee16.png openyahtzee32.png openyahtzee64.png openyahtzee.icoresulted in the alpha channel being reversed. I’ve used ImageMagick 6.4.0, and I didn’t remember this misbehavior happening in the previous versions.
While this annoyed, and was due to no apparent reason, it could be easily solved using the ImageMagick switches to reverse the alpha channel:
-channel Alpha -negateSo the command that produces a correct .ico file was:
convert openyahtzee16.png openyahtzee32.png openyahtzee64.png -channel Alpha -negate openyahtzee.ico
Odd. Thanks for posting your solution somewhere for the rest of us to find though, I wouldn’t have figured it out so quickly if you hadn’t.
Btw it looks like this issue is fixed in v6.4.9-7
@Kumar, it’s good to know that they fixed it, as this bug/regression was just annoying
