Answer 1

There is a pretty easy way to get the rect of a PDF page,

CGRect pdfPageRect = CGPDFPageGetBoxRect(CGPDFDocumentGetPage(myDocumentRef,pageNumber), kCGPDFMediaBox);

Three things will effect the size of the drawn PDF:

• CGContextTranslateCTM(ctx, 0.0, HEIGHT);//HEIGHT

• CGContextConcatCTM(ctx, CGPDFPageGetDrawingTransform(p,kCGPDFCropBox,MY_RECT, 0,true));//MY_RECT

• CALayer.tileSize

The Scale can also be effected by the two numbers in this function: CGContextScaleCTM(ctx, 1, -1);
