Been watching this one to see if anyone smarter about this sort of thing than me replied.
Guess I'll jump in with my limited knowledge in this regard.
I know for sure that things like brush strokes using brush-type tools (brush, clone, dodge, burn, etc.) cannot be scripted. It seems to me I read somewhere that manipulating settings of the "current tool" as you suggested cannot be scripted, either. I wouldn't stake my life on this, but after giving it some thought, it's a very practical idea.
Don't know if this would buy you anything: actions and scripts can select previously defined tool presets. Small consolation, however.
Hope this reply gets the attention of someone more knowledgeable in this area. If not, a good resource for scripting-type questions is the Scripting forum at www.Adobe.com
. Lots of shape programmer types hang out there. It's a little slow now (summer), but still worth a shot.
Sorry your first post at RetouchPRO didn't draw a crowd. Don't let that discourage you from participating in the future.
