Re: [weewx-user] WeeWX WebP image plots should they be an option?

[Paul R Anderson]

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

[Tom Keffer]

I like this idea.

I've created issue #758   to
look into allowing user-selectable formats.
