Hi, I am building on 10.4 and I would like to get a preview of a Quartz Composition. The API snapshotImage works only on Leopard. So I have tried unsuccessfully to lockFocus drawRect and unlockFocus then save the TIFFRepresentation, which results in an empty image. The line pdfData = [oQCView dataWithPDFInsideRect:[oQCView bounds]]; returns a white image.
Any idea? Should I work with the QCRenderer? Also, I have found pauseRendering and resumeRendering working on Leopard only too. So how to perform this actions on Tiger? The API stopRendering erases the QCView. My target is (on Tiger): I have a text list of QC files with their icons. I click on a row of the list and I see a static preview of the first frame of the QC in a QCView. I double click and I play the QC. Other double click and I pause the QC (still visible). May I have a pointer? Thanks.
