Get bitmap from screen data

[ghost]

I don't think it would be very difficult to code, but it would allow MANY more features, like for example animations that require the screen bitmap (am I clear in my explanation?)

You simply can not get a bitmap from the current screen data. This is not possible with most of the LCDs.

Hello Olikraus, Thanks for your answer. Sorry if I wasn't clear. What I mean is not getting the screen bitmap from the screen directly, but instead telling u8glib to store it in a variable (like XBMs) in the RAM while writing it on the screen. An example:

u8g.firstPage(); u8g.displayToBitmap(OutputVariableNameHere);

do { // something } while(u8g.nextPage());

Cheers

ok, you want something like a virtual display, which outputs to RAM instead of the actual display.

Yes, something like that. I think many people would use it, but, as I am not an expert C programmer, I don't know how easy it would be to code...
