Slowwwwwwwww
we too got the ipad for reading construction pdf drawings on the jobsite. the job we have right now has 300 pdf's. it takes forever to pull up a page and zoom in and mark it up or anything. in our research for a solution, we found the following:
"iPhone/iPad is a relatively slow device, compared to a desktop computer. And PDF format is very complex, it allows to format its internal data in a variety of ways. Some of those ways are what we call "iPhone-unfriendly", meaning that they overload iPhone's processor with a lot of unnecessary calculations.
However, there's a very simple workaround for this. If you have a Mac computer, open this PDF file in Mac's standard Preview application, go to File menu and select Save As command. Then resave this file as a new PDF (just make sure to change a file name, to preserve the original file unchanged). The new PDF file will be formatted in iPhone-friendly way. Unfortunately, we're unaware of a Windows-based solution for this issue."
Does anybody have any more info that could help us? We have all Window-based computers without even access to an Apple computer. We bought PDF Expert for our markups and what-not and that's the program we're using. But we've gotten 3 others and the slowness is still a major issue. Thanks in advance for you help!
