Hi All,
I have a few questions about rendering PDFs and wondered if anyone
here could help.
I've inherited some code that tiles the PDF, I think this code was
based on one of the Apple Sample Apps from a while back.
I'm rendering a PDF on an iPad, it's a magazine with lots of text and
obviously we'd like to run as fast possible, one thing that gives an
impression of "slowness" is the fact that it renders from bottom up,
so my first question, is there anyway I can make to render top down?
The idea is that when a user is presented with a page, that naturally
start reading from the top down, and since it's just a blur when
initially rendered it makes the experience less than pleasing.
The next thing is that I remember seeing some an article with some
sample code somewhere that altered the rendering parameters depending
on the type of iPad being used, e.g. iPad1, 2 or 3 (it probably
handling iPhone too, but I don't need to do that), but I can't for
the life of me find the exact article I read. I have found some code
on StackOverflow but doesn't seem complete. So if anyone could point
me to a some sample code that optimizes for the type of device or
documentation that explains what needs to be done, I'd be really
grateful.
Thanks in advance
Cheers
Dave
