I'm rendering PDF pages on iPhone using the code below. It works, but the margins seem much wider than when I view the same PDF using a Acrobat Reader or the Mac's Preview, and that consequently scales the content down much smaller than it otherwise would be. Is my code actually causing this behavior?
CGContextSetStrokeColorWithColor(context, backgroundColor.CGColor);
CGContextSetFillColorWithColor(context,backgroundColor.CGColor);
CGContextSetLineWidth(context, 2.0);
CGContextAddRect(context, CGRectMake(0.0,0.0, self.bounds.size.width, self.bounds.size.height));
CGContextDrawPath(context, kCGPathFillStroke);
CGContextTranslateCTM(context, 0.0, self.bounds.size.height);
CGContextScaleCTM(context, 1.0, -1.0);
CGPDFPageRef page = CGPDFDocumentGetPage(myPDF, (size_t) pageNum);
CGContextSaveGState(context);
CGAffineTransform pdfTransform = CGPDFPageGetDrawingTransform(page, kCGPDFMediaBox, self.bounds, 0, true);
CGContextConcatCTM(context, pdfTransform);
CGContextDrawPDFPage(context, page);
CGContextRestoreGState(context);
