accessing memory #20

Open RetroNick2020 opened 2 years ago

RetroNick2020 commented 2 years ago

I am trying to understand how to change the memory contents of a bitmap_t variable without using the graphic commands.

is the bitmap_t variable something i can use with memset/peek/poke ?

Wow, I completely wrote a wall of text and then realized that there may actually already be an answer to this...

I was going down a path of offering a set of suggestions but as I was walking through it and referring to the WIKI, I realized that (I believe) it has already been thought through.

@RetroNick2020, take a look at the following:

DIM AS BITMAP_t PTR b1 = BITMAP (64, 64, 2)
BITMAP OUTPUT b1
PSET(x, y), c
WINDOW OUTPUT '?????????

@gooofy I think the above will do what @RetroNick2020 is trying to accomplish, but I'm not seeing how to redirect drawing output back to the regular screen. Is it WINDOW OUTPUT?

not exactly. I need to be able to access the structure directly. I am outputting bitplanes for amigabasic, I need to be able to take the same data and store it in the BITMAP_t
