I am rendering PDF’s in my ebook reader app(iPad). Everything works fine in iOS

  • 0

I am rendering PDF’s in my ebook reader app(iPad). Everything works fine in iOS 4.2.1. But the problem arises when i run the same code in iOS 4.3.3. The font which is being displayed perfectly in 4.2.2 is not getting displayed properly in 4.3.3. Some fonts are being displayed with dark background colors and square boxes while some others are not at all being displayed.
I sense it has got something to do with the iOS version. Is it a bug from Apple side or should i do something to rectify this problem?

    PDFs can have the fonts embedded so that if the target system doesn’t know the font it doesn’t try any strange substitutions. What is the source of your PDFs? Are you able to check/change whether all fonts are embedded?
