[comp.windows.ms.programmer] Color Lookup Table

 Hi guys,

I like to know if there is a way to modify only "one", in a specified position, 
LUT RGB value.  For instance, the lut is 256 wide (s-vga 8bits) and I like 
to modify the rgb value of position, let say, 200 only.  
I found a way around this by reading in the present lut and modifying the 
rgb values for the particular position and then writing the lut (256 wide) back 
into the system.  However, this is not very efficient.

Thanks in advance.
