I got a 640x960 UIImage
of the screen, which is nice and crisp when re-displayed on the retina display. I'm thinking of a way to convert this image into a nice crisp PDF document page.
How would I go about converting a UIImage into a PDF page?
Do I need to make the resulting PDF to be 640x960, or does PDF automatically scale content (ex: 320x480 with the scale factor of 2)?
Thank you!
You will have to scale it by yourself. This link would help you in converting view to PDF.
UIGraphicsBeginImageContext(CGSize size); - not retina UIGraphicsBeginImageContextWithOptions(CGSize size, BOOL opaque, CGFloat scale) - retina
