Erase a single pixel in GIMP
I am trying to illustrate in GIMP 2.8 with pixel-perfect precision. The pencil tool allows me to fill in a single pixel without any fuzzy edges or anti-aliasing. However, the eraser tool operates more like a brush. I want to erase a single pixel (setting it back to transparent) without disrupting any neighboring pixels. Is this possible to do?
In the tool options for the eraser:
- Select the first brush (pixel).
- Select a size of 1.
- Select hard edge.
- Set Dynamics to Dynamics off
Then the eraser should do what you want.
(Also, do not forget that you need an alpha channel on the respective layer.)
