iphone - What is an appropriate PDF page size (dpi) for iPad? -

-

in case of drawing pdf quartz , supporting enlarging (using tilted layer), appropriate pdf page size (dpi) ipad?

currently, i'm drawing 3 viewes (previous, current, next) on scrollview pdf file. when scrollview scrolled , current page changed, old previous or next view removed , new or previous view created , added.

7,8,9 - (go next page) -> 8,9,10

in above situation, 100dpi pdf ok. pdfs on 150dpi encounter crash (memory problem).

in case of 150dpi, first 3 pages (previous, current, next) created , drawn app encounters crash after turning on pages 3 or 4 times.

please let me know size (dpi) if made ipad apps viewing pdfs.

as you've found out, depends on content. after trial , error, settled on around 100dpi. quite visual content - text content imagery go lot higher.

if you're having memory issues @ 150dpi , 100 works fine, i'd stick @ 100.
