Trying to read PICT data using Quartz functions

Hi All.

I have been uniformly unsuccessful in trying to read PICT data embedded in a data file. I have the specs for the data file, so I'm pretty sure I'm doing things right.

I have tried extracting the data and sending it to the functions QDPictCreateWithProvider and CGImageCreateWithJPEGDataProvider, which both return NULL. The PICT data seems to have all 0's in the beginning and start with the PICT header code 0x001102FF at 0x60 into the data. I have tried starting at 0 and at the PICT header and neither have worked.

Does anyone have more experience with PICTs?

Thanks a lot!

-Kenny
