I’ve worked on a MR to adjust all icon sizes for GIMP users in 4K, or for those who would like, or need, larger icons.
It’s a sprawling MR, that tweaks a lot of individual icons, a kind of retro fitting. The MR could be a lot simpler, if the functions throughout GIMP could access a couple of values as if they are global variables. This may not be doable, however a technique might be obvious to a software engineer.
The user sets two values through the ‘Preferences’ GUI in GIMP, which are stored in the ‘gui_config’:
they are also saved in gimprc:
Currently the MR has to pass around, or find a path to the ‘gui_config’, to then adjust the icon sizes. Which seems inefficient, and much yuck. If thou can help, please illuminate, thank you.
