Is it possible to invert a custom brush?
I am not talking about angle/rotation/horizontally but what part of the brush is drawn on the canvas.
I want to invert it in a way so the area which normally does not apply color will apply color.
A workaround: Paint black into a originally white layer mask. Have a new layer with white layer mask and the layer itself filled partially or fully with the new color. The layer must have alpha channel.
Windows>Dockable dialogs>Brushes
- Right-click the brush, and
Open brush as image
(image should be grayscale) Color>Invert
Two ways to use the brush:
- One-time use:
Select>Select All
Edit>Copy
- Use the
clipboard
brush (first in list)
- Long-term use:
File>Export
as .GBR, in one of the directories listed byEdit>Preferences>Folders>Brushes
(the one you can write into).
