Convert gif in webp keeping frames

[paul-mesnilgrente]

Hi,

I wrote something very simple like @image.format 'webp'. The image is a gif. But the webp contains only 1 frame. Is there an option to keep the frames?

Note that running convert test.gif test.webp in the CLI keeps all the frames.

I have imagemagick 7 installed and convert list -format has those lines:

GIF* GIF       rw+   CompuServe graphics interchange format
WEBP* WEBP      rw+   WebP Image Format (libwebp 1.0.3 [020E])

The "+" indicates that multiple frames is supported.

Hey,

Is there any update on this issue? At the moment we are having to resort to using https://github.com/minimagick/minimagick#metal to get this working. Would be great if the animated gif to animated webp conversion was supported by the normal conversion.

Thanks,
Richard

MiniMagick::Image#format by default selects only the first page, to avoid generating arrays of images it doesn't know how to handle, because it doesn't know whether source or destination format are multi-layer or not.

You can pass nil for the page argument to process all layers:

@image.format 'webp', nil
