I have a problem with rotating and cropping gif images

[bkstorm]

I have an image:

I want to rotate the image through 60 degrees then crop it.
Here is my command:

Code: Select all

convert bird.gif -coalesce -rotate 60 -crop 575x575+0+0! bird-crop.gif

With IM 6.7.2-7, it works just like what I want.

Your versions of IM are very old. I suggest you upgrade.

You need "+repage" after the rotate. I suggest you also insert "-background none" before the rotate, and "+repage" after the crop.

Thank you, it works. I will upgrade ImageMagick.
