using color tables with forms and bitblt?
by Lawson English 05 Aug '12

05 Aug '12

OK, I'm such a noob here, that I'm not quite sure how to ask my question... I have a "dwell file" -an array of values generated by a Mandelbrot Set application, one per pixel, with arbitrary values between 1 and xxxxxxxxxxx (currently less than 2 billion, and right now far less than 1,000,000)- and I would like to use them, suitably tweaked, as indices into a ColorMap. The ColorMap need not have 1,000,000 entries. No-one can see that many color differences in a Mandelbrot set anyway. I can generate an array of Color (ColorArray?) but I'm not sure how to use them to create the ColorMap, and I'm not sure how to use the ColorMap to speedily change what is drawn in the first place. Right now, I'm creating a color dictionary and drawing via: 1 to: 800 do: [:y| 1 to: 800 do: [:x| |i| i := x+ ((y-1) *800). aForm colorAt: x@y put:( myDictColors at: (myArray at: i )).] ]. where myDictColors is a dictionary whose keys are the dwells listed in the dwell array file and whose values are Color objects from my array of colors. Drawing the above takes about 1.5 seconds, which is a bit slow. I'd like realtime-ish updating as I play with colors in the palette. Can this be done, at least up to the 4096 color limit that BitBlt has for ColorMaps? If so, how? I've been trying to figure out the various classes and I'm stumped. Thanks -- Squeak from the very start (introduction to Squeak and Pharo Smalltalk for the (almost) complete and compleate beginner). https://www.youtube.com/playlist?list=PL6601A198DF14788D&feature=view_all

Three questions
by Mateusz Grotek 05 Aug '12

05 Aug '12

Hi I have the following 3 questions: 1. Why there is ContextPart>>releaseTo: ? What will happen if I don't use it? 2. Is there a bytecode editor for Squeak? 3. Are there any issues concerning bytecode editing, contexts, closures and compiled methods I should be aware of, which may break the image/create uncollectable garbage?

Ael's commit didn't change this method, and I merged it in, so I don't know why it got added. Seperate commit re-removes it. frank

I'm not sure if it's still true (or if it was ever true). Let's hope the tests will cover this case.
