I'm overriding -drawPage: in a PDFView subclass with the intent of
layering two PDFs on top of each other. It works great on screen, but
when I attempt to print the document, PDFKit just prints the document
PDFView rather than using my -drawPage: method. I've tried -[PDFView
print:], -[[PDFView documentView] print:], and -[PDFView
printWithInfo:autoRotate:]. All of them just pass the source PDF
right through.
Am I going to have to generate a new PDFDocument by hand?
I don't know if there is any way to get the PDFView to do what you
want, but, if you are targeting Leopard and onwards, an alternative
(and IMO better) approach would be to subclass PDFDocument and to make
your subclass create PDFPages of your PDFPage subclass, where you can
layer a page on top of the source page in the drawWithBox method. So,
you wouldn't need to create a new PDF document at print time, you'd
just have a different setup.
Lookup - (Class)pageClass in PDFDocument, and - (void)drawWithBox:
(PDFDisplayBox)box in PDFPage.
the drawWithBox method in a 'MYPDFPage' class would be something
roughly like:
- (void)drawWithBox:(PDFDisplayBox)box
{
[super drawWithBox:box]; // Draw source page
...
// Obtain page to superimpose
...
[superimposedPage drawWithBox:box]; // Draw superimposed page
}
pageClass in your 'MYPDFDocument' class would be something like:
- (Class)pageClass
{
// Instruct MYPDFDocument to create MYPDFPage objects instead of the
default PDFPage objects.
return [MYPDFPage class];
}
