Nice #jpeg #jpegxl #decoder written in C99 with no #dependencies https://github.com/lifthrasiir/j40 Very good job. What's great here is that they have found #bugs in the #specification in things like #modular #predictors and #dct #transformations - all of which will make the #core #library even better.
I should really do more to #compress the #images on #coffeespace and work harder on images for #deadsocial https://endtimes.dev/why-you-should-dith.. I may try out some #experiments later, apparently #png is way more suitable for #dithering than #jpeg - which has 3 channels baked into the #format ...
Nice work by #google on a new #jpeg #format named #jpegxl https://opensource.googleblog.com/2021/0.. One of the really interesting parts is in initially displaying something for the end user to see whilst the rest of the data is loaded. One of the things that can be done is displaying #polygon #svg #approximations of the image: https://coffeespace.org.uk/projects/poly..
Great article on #compressing #jpeg images: https://compress-or-die.com/Understandin.. The part about #alignment to the 8x8 grids is a new one on me, but makes perfect sense!
