I wanted to write a horizontal scrolling program using allegro in 640 x
480 x 256 resolution. Using ex19.c as a base, I increased the screen
bitmap size and changed the other screen size variables accordingly.
However, I found that *everything* on the screen was scrolled, including
the text line.
Is it possible to scroll only *part* of the screen while in an SVGA
mode, e.g., a 640 x 400 window? I noticed that in ex19.c you used a
mode X modex_split function. Does this mean that the split screen
text/scrolling only exists in mode X? Is there a version of
scroll_screen() that scrolls only part of the screen, or a BITMAP
Any pointers would be greatly appreciated.
