High quality UIImage from PDF

Question

I\'m converting a PDF page into a UIImage. While doing so, I lose the image quality. Need help in getting high quality images.

Code to generate UIImage

Answer 1

When you ask the PDF for it's page size, you're getting a width/height for 72 PPI. You might try creating a context that's scaled up using a scale transform. For example, if you wanted to render at 300 dpi, add a scale transform to scale by 300.0/72.0.

If you export as TIFF, you will be able to encapsulate the final PPI (300) of the generated image.
