How can I resize GIF/Animated WebP image files in Android

Question

How can we resize the gif and animated webp files in android? I was able to decode the webp and gif using glide but could not find the solution for encoding them into webp.

Answer 1

Finally I found the solution after lots of searching and exxperimenting.

For Gif:

• Extract frames from gif using decoder
• Resize the each bitmaps.
• encode them into webp or gif using encoder

For Webp:

• (Need Glid) use given code to extract frames as bitmaps.
• Resize them
• encode into gif/webp

(Delay is also available to use it with encoder)
