environment: Mac II 5 meg Think C 3.01 p4 the palette manager docs say that the first two colors in a palette should always be black & white, is this only for compatibility with 1 bit per pixel video cards or is there some other reason ? i'm writing some code that will never run on a system with less than 8 bits per pixel and i'd rather not be constrained to using black and white in the first two slots of my palette. e-mail preferred, posted replies appreciated as well thanks, ...!bbn!metasoft!spud

White and black should be the first and Last entries in the palette. I don't think it is absolutely necessary, but if you don't do this under MultiFinder (or not) you might get some strange effects when your window is brought to the front. -dave- | Dave Ewing | Internet: ewing@tramp.colorado.EDU (128.138.238.33) | 4437 Clipper Ct. | AppleLink: D2408 | | Boulder, CO 80301 | GEnie: D.EWING1 | The usual disclaimer about | | Compu$erve: 73447,1726 | having my own brain.

Well, Christmas 1990 gave me my first chance at playing with the palette manager a bit. I grabbed the custom palette and code from DTS's TubeTest (004) sample code and went about some modifications. Using standard quickdraw calls, I was able to animate anything I wanted. The only problem was what I wanted to animate was substantially more complicated that I wanted to create it in Studio/8 or another paint program, put it in a resource, use DrawPicture to draw it into my window, and then animate it. Is this possible? Anything imported into my window via DrawPicture refused to animate. Anyone have any tips? Any other programs I should use instead?

The notes I have on 32-bit QuickDraw include one on the enhancements to the Palette Manager. In particular, it is possible to set up the colour table in a source pixmap so that CopyBits will map the source pixels onto animating entries in the palette of the target window. All you have to do is set bit 14 in the ctFlags field, and the value field in each element of the ctTable array becomes a palette index, rather than a device CLUT index. I assume this works in a PICT as well: all you have to do is find and fiddle the appropriate bit, once you've created the PICT. You could use either DeRez/Rez or PICT Detective to make the job a little easier. Disclaimer: I've never tried this. It just *looks* simple...

Be careful about skipping QD. Those programs that do, will not run
properly on a 8*24 GC. Now that we have one of these in house, you
would be surprised about the number of programs that do not work. The
entertainment software is especially a problem.
