I'm a long time and proficient PhotoShop user trying to learn how to
work in GIMP.
My goal is to colour comic book style images using GIMP. I'm okay
with not having CMYK support, as my images are most likely to appear on
What I do is scan inked images with Xsane as line art. Then what I
want to do is create a layer that is pure black, and use the scanned
image as an alpha channel for that layer. That way I can add colours
underneath the layer, without affecting the line art.
However, I'm stuck as to exactly how to create that alpha channel. I
can create an alpha channel for a layer, but I can neither paste the
line art image into that alpha channel, nor can I seem to invert the
image so the right parts are transparent and the right parts are opaque.
Can anyone provide instructions or direct me to a tutorial for this
sort of thing? I will gladly RTFM if someone can show me where in the FM
Also, I have other concerns on the horizon which pertain to
colouring inked comic images using GIMP. Things like ensuring there is
no anti-aliasing when I use any of the tools. There are lots of
tutorials of this nature for PhotoShop, but I was unable to find any
that had GIMP specific instructions. If anyone knows of good directions
for comic art using GIMP, that would help a lot.
I look forward to any advice, and hope to hear from you soon.
