Hi ya;

I've never had problems QTNewGworld () for exporting images from RGB pointer buffers - using RGB32, RGB24, RGB48, RGB64 and Mono16 bit Images stored in buffers (Ptr type or dereferenced HLocked Handles).

You are using QuickTime's QTNewGworld() for your RGB24 buffer right - not QuickDraw's NewGWorld()? And your not trying to do "copyBits" or other QuickDraw type calls on the QTNewGworld() because that will cause major problems -as QuickDraw only understands the standard Mac GWorld types (1,2,4,8,16,32 bit RGB and 1 2 4 8 bit Grayscale)- not QuickTime's Extended formats.

HTH..

Hi,

I'm using Graphic Importers to extract image data to an offscreen GWorld. When the GWorld is ARGB things seem to work fine, but when I use an RGB GWorld, hell brakes loose, or in other worlds crash.
I tried creating a new GWorld, and wrapping one around a char* buffer using the RGB mode, but it just doesn't work. I've heard of several people having problems with this issue.
Can anyone (how about an apple engineer) explain why RGB buffers give us so much trouble, and we can avoid it?

Thanx
