WebDescription. Representation of RGBA colors in 32 bit format. Each color component is a byte value with a range from 0 to 255. Components ( r, g, b) define a color in RGB color space. Alpha component ( a ) defines transparency - alpha of 255 is completely opaque, alpha of zero is completely transparent. WebThe easiest thing is to first shift all the values so that min is 0, by subtracting Min from each number. Then multiply by 255/ (Max-Min), so that the shifted Max will get mapped to 255, and everything else will scale linearly. So I believe your equation would look like this: newval = (unsigned char) ( (oldval - Min)* (255/ (Max-Min)))
