OLED Screenshot?

[cgwaltney]

I have seen example of how to load an image from SD card and display on OLED

what i would like to do is the reverse... I call it taking s screenshot of the OLED

I understand the software builds an image buffer, which is a copy of the display
and then when commanded, pushes the image buffer to the display

i would like to build a command that pushes the image buffer to the SD Card
effectivly taking a screenshot of the oled display

lastly i was wondering if the image buffer can be converted to a bitmap so it can be correctly seen on a regular computer

I do not understand low level memory management

Thanks!

UPIR on Youtube has been working with OLED lately. He explains how the bits are stored (but not retrieved).
