One more gripe/question
by David Chase 01 Apr '02

01 Apr '02

What's with the scripting area? I'm playing with 3.0final, 2 processor PC, Win 2k sp2. I've been clicking on the scripting-area thing in the "tools", dragging left, and it just sits there unresponsive, unmoveable, un-anything. It did this before, but I thought I had messed something up with all my poking and clicking, so I started fresh. I thought this was where I was supposed to go and play. What am I missing?

[BUG] Reduce color depth requires 4GB of memory
by Ned Konz 01 Apr '02

01 Apr '02

The comment in Form>>copyWithColorsReducedTo: Note: this has not been engineered. There are better solutions in the literature. I bet we could do it with less than 4GB of memory! Read in a 54x60 GIF file as a SketchMorph. Choose painting.../reduce color palette/2 (same with 3). My desktop is in 32-bit depth. The corner pixels of the image are transparent.
