Reason: I use colored guidelines for drawing and need to remove the lines when the sketch is done and has been scanned.
Here is the original image, which would be scanned in from a sketchbook or piece of paper.

I used this imagemagick command:
Code: Select all
convert red-grid-skater.jpg -fuzz 30% -fill white -opaque 'rgb(255,0,0)' im-out.jpg

There is still a lot of the guidelines visible. Is there a way to improve the results?

Btw, how do you embed images here? My dropbox links are not being embedded.
