[Adonthell-devel] Handling edge pixels on scanned images.

[Sasha Kushnirenko]

Hi,

I finally managed to interest 2 possible artists to make drawings.  They
draw images on white paper, which is scanned afterwards.  We got around
"purple noise" problem following instructions from "Adothell Graphics
Manual"

But as images are drawn on white paper and scanned - all images suffer the
same problem - edge pixels are usually some lightish color (mix of white
paper background and for example brown hair foreground color) .  So all
images have "whitish border" 1 pixel wide around them.  This border is
clearly seen when placed on green background.

Is there a simple way to get rid of those pixels.  We use gimp to
manipulate images.

Sasha.
