Hi,
How do I set the graphics mode to 640x480x256, and then draw 256 bars
(filled boxes) that go from one end of the monitor to the other? Such as
a gradient. Here's my code (all req. headres are incl. in the original).
The most trouble I have is, is setting up the graphics. Isn't there a
#define that simplifies all this (esp. the last 3 args. in GrSetMode())?
void main()
{
int x; long fbc;
GrSetMode(GR_width_height_graphics,640,480,256);
for(x=0;x<=256;x++)
{
fbc=GrAllocColor(x,x,x);
GrFilledBox(x+1,0,x+2,480,fbc);
}
getch();
}
All I need is a simple gradient. Please help!
Thanks!
