Unfortunately due to a bug in Ubuntu I had to recompile imagemagick myself.
题
I am trying to use Wand (http://docs.wand-py.org/en/0.3.5/) library to transform images server side.
I installed libmagickwand-dev on my Ubuntu server.
I can work with jpg and png images but I get an error message when trying to transform a webp image:
no decode delegate for this image format `' @ error/blob.c/BlobToImage/346
Any idea how to get Want support webp images on Ubuntu 12.04 LTS?
UPDATE: I have also installed libwebp-dev, still getting the same error.
