Just annotations of little "how to's", so I know I can find how to do something I've already done when I need to do it again, in case I don't remember anymore, which is not unlikely. Hopefully they can be useful to others, but I can't guarantee that it will work, or that it won't even make things worse.
GIMP is much lighter than Krita on older hardware, but its GUI lacks some handy features, particularly when one's painting or drawing.
While MyPaint has some of those GUI features, it lacks some things like even basic transformations to selections.
These functionalities are the ability to use the stylus' "right click" (or whatever button it is) as a color picker, and handier/"exposed" buttons for undo, redo, mirroring view, de-selecting , resetting rotation,...
Apparently on GIMP you can't set the stylus button 3 as an instant color picker. The default is to hold control and click, which is not that much of a hassle, but it's interesting to have this kind of functionality more uniformly activated.
A hacky way of getting an approximation of it is along the line(s) of:
Code:
while true ; do xdotool getactivewindow getwindowname | grep GIMP && xsetwacom set "Wacom Bamboo Pen stylus" Button 3 "key Control button
These are the original images to be cropped in batch, all jpegs, all in the same folder:
(It's a single image here, but these are in fact separate files)
The next step is to create a montage (still done manually):
GIMP 2.9 may fail to start due to some MyPaint brushes failing to "deserialize", whatever that means.
In order to "solve" that you don't need to get rid permanently of such brushes, which may still work fine on MyPaint itself.
Instead, move/rename the .mypaint user folder (perhaps ~/.config/mypaint to some?) to mypaint-temp or whatever, run gimp 2.9, it will start. Then go to preferences, folders, and change the mypaint-brushes folder settings, but...
Apparently there isn't much system-wide preview support for formats such as XCF and ORA. It used to be better at some point, at least when KDE was mostly QT4, at some point I had fancy thumbnail previews of everything. Everything! Gwenview apparently was also at some point able to preview ORA and maybe the others, but I've never seen that.
So, unfortunately I'm not a programmer or anything, so I can only look for poor man's solutions like a script that converts such files into more...
