With JPG data, if: - An incremental CGImageSource is used, - it is updated with incomplete data - then updated with complete data from a direct provider (NOT with CFData) - then is used to create a CGImage Then: - That CGImage will fail to draw into a PDF. Sample code attached [contact me if you want it]. To use the sample code, compile it. Run it under 10.5 and see that it creates a PDF file and opens it. There will be an image in the PDF. This is correct behavior. Run the app under 10.6.x. It will generate a PDF and open it. The PDF will appear to be blank. If you inspect the PDF you will see that the image is present but has no data. --- We believe this issue has been addressed in Mac OS X Lion Developer Preview Build 11A390.
