Hi Tom,
Glad you like the idea. Really impressed with the file size and image
quality using WebP.
Only had to hack two changes to imagegenerator.py
Change hard coded '%s.png' 'to '%s.webp'
And because I needed to pass in a option
# Now save the image
image.save(img_file,lossless = True)
ngen += 1
Sorry for duplicate messages, sometimes google groups hates me and blocks
my post :)
Thanks,
Paul
