hi guys i was thinking if you can give options to us developer to save preload image to disk, so when the user go back to some part of pdf that he/she already read, we just load the preload from the disk instead of blank background, is this possible?

    Thanks for your suggestion.
    We've developed this caching system, but there are some drawbacks that prevents the immediate inclusion in the deployed version.

    Probably we will, but i cannot give you an eta.
    With some graphically rich pdf the performances get a huge gain after the first rendering, but the support for every device orientation and single/double page need to be considered accurately.
    Also to get best performance and reduce disk usage we need to use jpeg compression losing transparent background (replacing it with a plain color).
