WebP Alpha support #326

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
Right now WebP is supported in the 3.0 beta 3, 
but Alpha channel still needs implementation. 

Thank you! ;)

Alpha channel should be supported. Do you have an image where it doesn't work? 
And is that image made using the latest WebP tools? The format is still in flux.

Oh, I see. Definitely, I'm using the latest beta version (libwebp-0.3.0-rc6) 
for generating the image.
Just in case, I'm attaching it.

The background should be rendered as checked, but is being rendered as white.

Thank you!

Thanks, I'll look into it later when I get back to development.

Looks like I broke it at some point because I actually believed what the WebP 
documentation says.

I tried guessing what I was actually supposed to be doing and it seems to work 
again now.
