Batch convert to apng

I'm using ImageMagick 6.9.7.4 on Ubuntu 17:10. I'm trying to convert a folder full of .gifs to .apng files. I'm doing this by running
. However, when I run this I get the following error:
Code: Select all
mogrify-im6.q16: unable to open image `apng:': No such file or directory @ error/blob.c/OpenBlob/2701.
mogrify-im6.q16: unrecognized image format `apng' @ error/mogrify.c/MogrifyImageCommand/4927.
If I choose any other format it works, and also if I use the convert command to convert one file. Is this an error with mogrify?

"mogrify -list format" will show you a list of formats that program can read/write. In my rather old versions of IM, "apng" isn't among them.

I do not believe Imagemagick supports APNG only MNG

That's interesting! I converted all of the files to apng by running
Code: Select all
for file in *.gif ; do convert $file ${file%.*}.apng ; done
I ran identify on one of the files and it returned this:
Code: Select all
email.apng[0] GIF 55x60 55x60+0+0 8-bit sRGB 256c 24.6KB 0.010u 0:00.000
So it seems you're right!

My guess is outputs the same as the input, since it shows GIF as the format. It does not recognize the desired apng and just outputs the input.

If you would like ImageMagick to support APNG, you can add a message to this request:
