Pencil and eraser are counterparts of course, but I wished for transparent color, not just transparent pencil (yes, it exists, and it is eraser). > From: Chris Moller <[EMAIL PROTECTED]> > Doesn't the Eraser Tool do what you need?

Because once you have transparency as your color you could use any tool which works with colors. > From: Simon Budig <[EMAIL PROTECTED]> > Well, historically new stuff always had to proove that it is better > than the old stuff and I personally don't think that is a bad > thing.

Good example, because it shows how natural transparent color is. The answer: you should get exactly the same effect if you have blue color and paint on top of semi-transparent red. It depends on mode and used tool. > Currently it gets blended on top of the blue resulting in some kind > of violet and that is a widely used feature to do natural looking > paintings.

I don't understand that paragraph: a) the transparent color is not a replacement, I clearly stated this in original post, it is addition to the color palette b) don't pick the transparent color if you don't need it > How is your "replacement" approach supposed to work with multiple > layers? Again, it is not a replacement. Honestly, I didn't thought of this issue -- it can be done, but to achieve intuitive behaviour it should be well designed not to change too many things. So here is the problem now... pity. > From: David Odin <[EMAIL PROTECTED]> > So your wishes are granted too. There are already tools for that > in the gimp toolbox: eraser and smudge. See above.
