Adding painting-friendly GUI functionalities to GIMP with questionable bash scripts and openbox configuration

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,...

Proof of concept script to make GIMP more similar to MyPaint or Krita, for painting/drawing

Posted 06-13-2018 at 03:37 PM by the dsc (linux-related notes)

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

Batch-cropping with ImageMagick + GIMP. Script helper(s), in development

Posted 12-09-2017 at 02:21 PM by the dsc (linux-related notes)
Updated 12-14-2017 at 11:01 AM by the dsc (mumbling about possible improvements)

Here's the explanation:


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):

montage -define jpeg:size=220x -geometry 220x220 *.jpg montage1.png

And then it's edited on GIMP: gimp montage1.png

[SOLVED, kind of] GIMP 2.9 fails to start due to incompatible (?) MyPaint brushes

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...

Poor, but acceptable, work-around to the lack of image previews for XCF and ORA (maybe other formats as well)

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...
