I'd like to adopt and upgrade libwebp to date as it is now up to 1.2.2
from 0.6.1 and available and supported in most distros and all browsers
(including our Qupzilla) except (unsupported) IE and older packages:
https://cygwin.com/packages/summary/libwebp-src.html
The cygport is available in the libwebp package git repo playground branch:
https://cygwin.com/git/?p=git/cygwin-packages/libwebp.git;f=libwebp.cygport;hb=refs/heads/playground
and the packages have been built under scallywag:
https://cygwin.com/cgi-bin2/jobs.cgi?srcpkg=libwebp
logs in:
https://github.com/cygwin/scallywag/actions/runs/1771264878
I picked up the package because I thought our images at
cygwin-htdocs/goldstars/img/ seemed large for small icons:
$ wc -c img/*
3473 img/dungbomb.png
1074 img/goldstar.png
1303 img/goldwatch.png
9382 img/pinkwatch.jpg
877 img/platinumwatch.jpg
878 img/plush_hippo.jpg
1055 img/silverstar.png
18042 total
so converted them and found they were much smaller in webp format, and
reconverting using the upgraded package command:
$ cwebp -blend_alpha 0xffffff img/$img -o images/$i.webp
$ wc -c images/*
220 images/dungbomb.webp
284 images/goldstar.webp
286 images/goldwatch.webp
322 images/pinkwatch.webp
232 images/platinumwatch.webp
204 images/plush_hippo.webp
174 images/silverstar.webp
1722 total
Those images are attached if anyone wants to standardize the images in
the directory and update the img src file types in goldstars/index.html.
Conversion of all cygwin-htdocs web site images to webp (including using
`gif2webp -mixed` and converting X2.bmp to png then webp) would reduce
the total image sizes from 907008 to 236842: details are attached.
Updating these would make the site more mobile friendly, quicker for
those on low-bandwidth connections, and cheaper for those on expensive
plans.
