how to parse pdf document in iphone or ipad?
- by JohnWhite
I have implemented pdf parsing application for ipad.But content of pdf display not clearly.I dont know why this happning.can you help me for this problem.
Edit:
I have used below code for pdf parsing.But text and image is not clear.
(id)initWithFrame:(CGRect)frame {
if (self = [super initWithFrame:frame]) {
// Initialization code
/*
Demo PDF printed directly from Wikipedia without permission; all content (c) respective owners
*/
CFURLRef pdfURL = CFBundleCopyResourceURL(CFBundleGetMainBundle(), CFSTR("2008_11_mp.pdf"), NULL, NULL);
pdf = CGPDFDocumentCreateWithURL((CFURLRef)pdfURL);
CFRelease(pdfURL);
counts+=1;
self.pageNumber = counts;
self.backgroundColor = nil;
self.opaque = NO;
self.userInteractionEnabled = NO;
}
return self;
}
(void)drawRect:(CGRect)rect {
// Drawing code
CGContextRef context = UIGraphicsGetCurrentContext();
// PDF page drawing expects a Lower-Left coordinate system, so we flip the coordinate system
// before we start drawing.
// Grab the first PDF page
CGPDFPageRef page = CGPDFDocumentGetPage(pdf, pageNumber);
CGContextTranslateCTM(context, 0, self.bounds.size.height);
CGContextScaleCTM(context, 1, -1);
// We're about to modify the context CTM to draw the PDF page where we want it, so save the graphics state in case we want to do more drawing
CGContextSaveGState(context);
// CGPDFPageGetDrawingTransform provides an easy way to get the transform for a PDF page. It will scale down to fit, including any
// base rotations necessary to display the PDF page correctly.
CGAffineTransform pdfTransform = CGPDFPageGetDrawingTransform(page, kCGPDFMediaBox, self.bounds, 0, true);
// And apply the transform.
CGContextConcatCTM(context, pdfTransform);
// Finally, we draw the page and restore the graphics state for further manipulations!
CGContextDrawPDFPage(context, page);
CGContextRestoreGState(context);
}
Please help me solve this problem
