LoadRGB32 -- Set a series of color registers for this Viewport. (V39)
LoadRGB32( vp, table )
a0 a1
void LoadRGB32( struct ViewPort *, ULONG *);
vp = viewport
table = a pointer to a series of records which describe which colors to
modify.
The selected color registers are changed to match your specs.
Passing a NULL "table" is ignored.
The format of the table passed to this function is a series of records,
each with the following format:
1 Word with the number of colors to load
1 Word with the first color to be loaded.
3 longwords representing a left justified 32 bit rgb triplet.
The list is terminated by a count value of 0.
examples:
ULONG table[]={1l<<16+0,0xffffffff,0,0,0} loads color register
0 with 100% red.
ULONG table[]={256l<<16+0,r1,g1,b1,r2,g2,b2,.....0} can be used
to load an entire 256 color palette.
Lower order bits of the palette specification will be discarded,
depending on the color palette resolution of the target graphics
device. Use 0xffffffff for the full value, 0x7fffffff for 50%,
etc. You can find out the palette range for your screen by
querying the graphics data base.
LoadRGB32 is faster than SetRGB32, even for one color.
