Example Pseudo Code:
float coeff7 = 1.123f;
float coeff7_scaled = coeff7*4096.0f;
// factor = 4599.808
int value = (int) round( coeff7_scaled ); // value = 4600
# color_cross 4096 0 0 0 4096 0 0 4600 4096

color_cross_offset <red_offset> <green_offset>
<blue_offset>
Sets the color cross talk offset in the FPGA.
In addition to the matrix multiplication an offset can be added to the pixel values for R, G
and B separately. This offset is applied after the matrix multiplication.
The offset values are two’s complement integer numbers with a range of -2048 (0x800) to
2047 (0x7FF). 0 is represented as 0x000.
