How does this work? Can anybody explain to me? Is it simply done by connecting lines that consist of the same color to a vector? Such as in Interfont Designer?

Obviously it cannot be done byconnecting lines, since there ARE no lines as such yet - I am referring to a program that FINDS, or DEFINES, lines - out of the chaos of bit-maps. Repeat, automatically, and at reasonable timing. There are a couple such programs, I hear, one I use. It does not work with color because you don't always get color bitmaps in Mac programs in the first place. This one (Aldus Freehand) is state of the art, yet V2.0 does not handle color bitmaps. > >Anyway - another thing the Amiga community lacks. But we have better colors, did you notice the colors?

Sure it is! >>How does this work? Can anybody explain to me? Is it simply done by >>connecting lines that consist of the same color to a vector? Such as in >>Interfont Designer? loosely put, the program scans the bitmap line-by-line. When a non-background color is found, that location is tagged and then the algorithm proceeds to trace around the edge until it reaches where it began. The list of coordinates from point to point of the scanned area is now processed to remove excess vertices and perhaps to smooth it out some. And there you have it! >There are a couple such programs, I hear, one I use. It does not work >with color because you don't always get color bitmaps in Mac programs >in the first place. This one (Aldus Freehand) is state of the art, >yet V2.0 does not handle color bitmaps. There are a couple of programs on the Amiga that will do that too- also, the software that I am currently working on will be able to do that, too. So sit tight!
