Thanks Andreas,
Honestly, I'm not sure. For starters, the world/fixSketches script is a bit of magic I don't understand, not to mention that it's apparently a text-only script. However, I don't think this addresses one of my wishes - which is to be able to set the color of a sketch's stamp (multiple stamps, multiple colors, assigned by an RGB vector).
The stamp in Andreas' example has the right color, doesn't it?
So what you need is setting the color from RGB. There is a nice apparatus for visualizing the RGB color model: the color cube. You can even buy on at
http://www.colorcube.com/puzzle/puzzle.htm
It's made by arranging tiny cubes in a three-dimensional grid according to their colors. Black is at the origin (0,0,0), white at the opposite corner (1,1,1).
This cube can be simulated with an etoy project, and thus positions converted into colors. Here's how:
- Make images of the color cube sliced into layers. Just drop the
attached images into a holder:
Thanks Bert. I'm all too familiar with the RGB color model, having done computer graphics for many years. If you *generated* those slices in etoys (via a script), *that's* what I'd love to see. I added a section "Coloring stamps" on my web page which will hopefully shed some light on what I'd like to do: http://poincare.uits.iupui.edu/~heiland/squeak
