As usual, the major part of the illustrations was made on Krita for Android (on tablet).
But I tried the rest of my workflow using only my #RaspberryPi : further editing in #Krita, #Inkscape, #Gimp, then compressing the images with #pngquant, and then finally publishing on the blog. It definetely works! 😃

I just use #pngquant. Works tons better than e.g. GIMP.
> pngquant [n] <inputfile>
generates a png file quantised to n colors, using Floyd-Steinberg dithering, and compresses better than most others. You can turn dithering off with the --nofs option.

To get line graphs in svg or eps format into presentations, I export to png with 600dpi (no anti-alias!), then quantize if needed. The result is often smaller than the EPS, and always smaller and better-looking than jpeg.

Bin ebenfalls bei #ocrmypdf gelandet (für einzelne PDFs, aber lässt sich ja scripten). Normalerweise überspringt es OCR, wenn schon ein Textlayer vorhanden ist.

Was ich besonders mag ist auch die Option, den Inhalt per #pngquant verlustbehaftet zu komprimieren, falls das installiert ist.
