Hi!
How do I transfer a block (e.g. a screen 640x480) from one place in VRAM to
another place in VRAM, without moving it to plain RAM first?
I think it's possible, and Allegro's blit-function is too slow. I think
that the statement
blit(screen, screen, ....., screen->w, screen->h)
would transfer the screen to plain RAM first!
The VRAM to VRAM method and the scroll_screen in Allegro, could make a very
fast double buffering system!
If anybody know anything about this, please help me (I'm quite new to this)!
Thank you,
Nils Emil P. Larsen
