I'm building something with a compiler target of 10.4, and keep getting told that DisposeGWorld is deprecated. There doesn't seem to be anything in the documentation or header files that should be used instead...am I missing something?



OK, so I'm being a little slow tonight. DisposeGWorld is a QuickDraw function, and so deprecated in Tiger. However, the rest of the calls I'm making (eg QTNewGWorldFromPtr, GraphicsImportDraw) are QuickTime, and not deprecated (right?)
So what's the QuickTime equivalent of DisposeGWorld?


For Tiger and later, your best bet is probably to replace that code with CGBitmapContextCreate and the image import routines in Image I/O.

Thanks for the pointers. Took a while, but it's finally working. Though I was a little disappointed to find that it's actually a little slower than the original QuickTime code...
Are there any resources anywhere that talk about the best way of getting an image from Quartz to OpenGL? My app is currently spending a vast amount of time in gleExtractPixel_BGRA_8888Rev (in glTexImage2D).
