Actually doublebuffering or pageflipping routines could easily use these functions for optimizations. The thing is, that as soon as you swap out one bitmapdata for another (or the holder bitmap class), you lock it anyway.
The lock function on itself does not replace the functions of a double / triple / frame buffer or a pageflipping routine. But you could easily intergrate these functions. I've did some speed comparisons; lock and unlock make a great deal of difference in speed; if you are writing a large amount of pixels, rectangles; be sure to lock first.

To improve performance, use this method along with the unlock() method before and after numerous calls to the setPixel() or setPixel32() method. " With this in mind, it does seem to function like a double buffering mechanism, since you can actually alter bitmapdata before showing it on screen, therefor avoidoing the image to show while processing it. -Meinte On 8/16/06, dan <[EMAIL PROTECTED]> wrote: > > WHEN IS FLASH WITH AS3 COMING OUT? > NOT THE BETA? > ANY IDEAS? > > > _______________________________________________ > [email protected] > To change your subscription options or search the archive: > http://chattyfig.figleaf.com/mailman/listinfo/flashcoders > > Brought to you by Fig Leaf Software > Premier Authorized Adobe Consulting and Training > http://www.figleaf.com > http://training.figleaf.com > _______________________________________________ [email protected] To change your subscription options or search the archive: http://chattyfig.figleaf.com/mailman/listinfo/flashcoders Brought to you by Fig Leaf Software Premier Authorized Adobe Consulting and Training http://www.figleaf.com http://training.figleaf.com _______________________________________________ [email protected] To change your subscription options or search the archive: http://chattyfig.figleaf.com/mailman/listinfo/flashcoders Brought to you by Fig Leaf Software Premier Authorized Adobe Consulting and Training http://www.figleaf.com http://training.figleaf.com
