Re: [Gimp-user] Enhancement request: Transparency as a "paintable" color

[scl <scl gplus gmail com>]

Hi Brendan,

does the 'Color Erase' painting mode in the
Paint tools dialog solve your problem?
See http://docs.gimp.org/en/gimp-tools-paint.html#idp11582648

It erases parts of the layer that are painted in the foreground
color. To achieve partial transparency use the Opacity
slider. Note that you have to right click on that particular
layer before and select 'Add Alpha Channel' from the
context menu.

Kind regards,

Sven
