Unable to generate webp tiles

[julienrf]

I saw that there is TYPE setting but it seems only png image/png is supported. Is it possible to produce webp files? I’ve observed that webp files are less than half the size of their png equivalent for a very small loss of quality:

$ ls -hl
-rw-rw-r-- 1 julien julien 42K Dec 10 21:19 biella.png
-rw-rw-r-- 1 julien julien 16K Dec 10 21:50 biella.webp

biella.png:

biella.webp:

@julienrf There is a pull request which allows this to be done by adding outputFormat to TYPE so setting TYPE to webp image/webp webp would do what you are asking about. I have rebased it on the current codebase and left a comment here.

That’s fantastic, thank you @hummeltech for helping with that!
