HSV_TO_RGB Procedure

Standard Library procedure that converts colors from the HSV color system to the RGB color system.

HSV_TO_RGB, h, s, v, red, green, blue

h The hue variable. May be either vector or scalar, in the range of 0 to 360.

s The saturation variable. Must be the same dimension as h, in the range of 0 to 1.

v The value variable. Must be the same dimension as h, in the range 0 to 1.

red Red color output value(s). Will be short integer(s), the same dimension as h, and in the range of 0 to 255.

green Green color output value(s). Will be short integer(s), the same dimension as h, and in the range of 0 to 255.

blue Blue color output value(s). Will be short integer(s), the same dimension as h, and in the range of 0 to 255.

None.

HSV_TO_RGB provides a convenient way to convert from the HSV (hue, saturation, value) color system to the RGB (red, green, blue) color system. Most output devices capable of displaying color use the RGB color system.

The statement:

HSV_TO_RGB, 0, 1, 1, red, green, blue

returns red=255, green=0, blue=0. You can use the red, green, and blue values to set color table values with the TVLCT procedure.
