iBooks has a limit size of below 1 GB

  • I have been doing some experiments making iBooks for a large museum tour.
    Did not work very well.

    My tour is 1.5 gb and when exporting it from iBooks author it just starts loading on iPad and then quits after 5 sec.
    To find out the limt I removed panoramas and found that 1.2 gb still did not work but at 884 mb it worked fine.

    Apple says that 2 BG is maximum but it maybe that the problem is that the tour is one single 15 GB widget.

    Unfortunatelly I also found another problem. Images in HTML text popups does not work.

    I also have some problem with the distorted arrow hotspots I use on the floor, they do not work in my last tour even if the code is identical from the tour I made 2 years ago.

    The standard arrows made by the toureditor seems to work fine.

  • After some more tests I found that the size problem is only associated with the preview export from iBooks author.

    I could export the full 1.5 GB iBook to the desktop and then import it to iTunes.
    Now it was no problem transferring it to the iPad.
    Took about 20 minutes.

    Need to figure out if the image problem in the textpopups can be solved.
