Released ScreenSavers 0.6.N!
With a few tweaks to the ImageMagick processing settings*, meaning we get prettier covers
.
(If you want to invalidate your current cover cache, delete all the
cover_*.png files in the
linkss/cover_cache folder before applying this update
).
[*]: Always use the Lanczos filter when resizing (I read the doc wrong, I thought the default were Lanczos when upscaling, Mitchell when downscaling [because it made sense to me, Lanczos generates sharper images than Mitchell], but it's the other way around. Since Mitchell is blurrier than Lanczos, we were getting slightly blurry images when upscaling).
And since Lanczos is sharper, it has a tendency to make JPEG artifacts stand out, so I caved, and added a dithering step (FloydSteinberg, 16 colors), which actually helps in more cases than that (every time, really
), and we end up with smaller filesizes, so, win-win
.
The only downside is a longer processing time, but since we're already eating ~10s of CPU time, what's 5s more?
