Save part of the screen
October 29, 2013 06:14PM
Hi Jim

I need to create a process for storing a portion of the screen, to return later. Ie: invoke a virtual keyboard, put data and when I give enter, I want to make the virtual keyboard disappear and restore the previously saved image.
I think it is possible to store the RAM portion of the screen, using a string and peekc function.

But I need more tips to understand:
structure and data positions mem screen;
flow collection;
Flow replacement.

Can you help me

Ok, but
please can at least give me the address where I can start reading the screen in terms of pixels at the byte level.
Already understood how the format bmc has the pixels and each pixel consists of 3 bytes each 0-63.
