After researching it seems like some of the functions (imposition with crop marks, page cropping/scaling with/without preserving aspects, etc) are best suited for quartz, while the rest (page reordering/inserting, rotating, etc) have Cocoa APIs. Well, FWIW, Apple's Preview is cropping in PDF Kit ... basically you call -[setBoundsForBox:] on the PDFPage in question. Additionally you should probably look into subclassing PDFPage. Within that domain you can overlay crop marks, apply additional transforms, etc. See PDFCalendar sample code for a PDFPage subclassing example.

Re: PDFDocuments and CGPDFDocuments
Whoops, I sent this yesterday but didn't hit reply-all... Thanks Joel, I just took a look at the PDFAnnotationEditor example. It seems to be doing all of it's transformations in the PDFView subclass. I'm not sure if I am able to do this since I would like to perform the impositions by working strictly with the data of the PDFDocument. David's book is fantastic, I'm been using it plus a lot of inspiration to get to where I am now. It has been essential on this journey. In my naiveté, I had hoped that I could cast between the two with a smaller performance penalty than converting PDFDocument - NSData - CGPDFDocumentRef. Needless to say, there has been no headway on that front. I currently have an Initilalizing... document modal window activate when I'm initializing the CGPDFDocumentRef so it's not too bad, it would just be nice to avoid this behavior completely. I realize that perhaps this question might be better suited for quartz- dev, thank you for your insight! - Kevin On May 29, 2008, at 8:52 PM, Joel Norvell wrote: Kevin, The PDFAnnotationEditor example program does a lot of this sort of thing; have you looked at it?

Joel was right. I think it would be easier for you to stay in PDF Kit (PDFView) and do your transforms there. Since I don't know exactly what you are doing, I can't recommend specific advice. If you explain what you think you need to do with CGPDFDocumentRef, I'll try to suggest a parallel way of doing it in PDF Kit.

PDFDocuments and CGPDFDocuments
Hi everyone, I seem to have run into a little snag recenlty. I have an application that manipulates PDF files (scaling, imposition, transforms...). I am using a PDFView for the interface but performing all of the transformations in Quartz. I find myself shuttling data back and forth by using CGDataProviderCreateWithCFData((CFDataRef)[pdfDocument dataRepresentation] before the transformation and [[[PDFDocument alloc] initWithData:(NSData *)cgPDFAsMutableData] autorelease] after to display in the PDFView. I'm getting bottlenecks for larger files in the calls to [document dataRepresentation]. I think there has to be either a better way of doing this or a way to do it where I will not have to convert (PDFDocument *) to CGPDFDocumentRef every time I perform a transformation. Does anyone have any suggestions? Thanks! - Kevin ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
