Hi!

The following tile cropping example works for jpg and png output format:

convert file.jpg -crop 25x25 +repage +adjoin jpg:tile
It will correctly create several files such as tile-0, tile-1, tile-2, etc

But if you use webp output format:
convert file.jpg -crop 25x25 +repage +adjoin webp:tile
It will only crop the very first tile and name it just 'tile'.

ImageMagick 6.9.5-8 Q16 x86_64
webp 0.5.1

Is that a problem with WebP library from Google or somewhere in ImageMagick?

Thanks!

This works just fine for me on IM 6.9.5-9 Q16 Mac OSX.
as does this
I get tmp-0.webp thru tmp-8.webp

I think you should be adding a suffix.

Are you sure IM can see your webp delegate library. Does it get listed when you do

No, its not listed.

I'm also using Max OSX and both webp and IM are installed using brew. Strangely I can output proper webp images using


but I don't get multiple cropping tiles.

I'm going to reinstall both with brew now..

I've reinstalled IM with

brew install imagemagick --with-webp

(brew re-compiled it from source instead of pouring)

And it works correctly now. Thanks!
