Hello

It seems like cropping certain uncommon animated gif results in the loss of the loop
the animation will only play once then

I use the command

trimmer=`convert image.gif -coalesce -flatten -format %@ info:`
convert image.gif -coalesce -crop $trimmer +repage result.gif

anybody knows why it happens on certain gif
and is there any way to fix the loop?

thank you

Your command works fine for me on IM 6.9.7.2 Q16 Mac OSX. What is your IM version and platform? Perhaps you need to upgrade.

Please always provide your IM version and platform in the future.

Near the top of the page at THIS link it describes the delay and loop settings. You might be able to add "-loop 0" just before the output of your command to fix the issue...

Thank you so much Good Sir, once again you're spot on, you truly deserve the title of magician


@fmw42
thanks for the advice, I'll provide IM version next time I ask a question

If you read my message above, you will see that it worked fine for me. I animated and looped continuously for me. No addition of -loop 0 was needed. That was why I asked you for your IM version to see if you needed an upgrade.

i use IM 6 from jessie repository
6.8.9.9-5+deb8u6

I can't update IM freely or I wouldn't be synched with the repository anymore, which wouldn't be safe

this might be a bug in an earlier version
anyway the loop option is a great workaround so everything is fine now
