If I were looking for the super-ideal "correct" algorithm and hade infinite coding monkeys, I would at init time create bitmaps of every library item, and use flood-fill combined with trig math to generate vector "trace" shapes of the non-white areas, which I would draw as zero alpha shapes into a movie clip attached to each raster movie clip. And then iterate throgh the display list calling hitTest on these invisible shapes. You'd avoid any code to copy bitmap data, would still be able to otherwise treat your clips as normal clips, and would get pre-built hitTest() behavior for the vector shaps, without having extra design-time work when images are added. The code to convert a bitmap into vectors would be the tricky part, but is technically doable.
I may be tired as well. Just thinking outside the box. On 2/7/07, Dave Wood <[EMAIL PROTECTED]> wrote:
