WebTypically, RGB values are encoded as 8-bit integers, which range from 0 to 255. It's an industry standard to think of 0.0f as black and 1.0f as white (max brightness). To convert [0, 255] to [0.0f, 1.0f] all you have to do is divide by 255.0f. If you care, this is the formula to convert back to integer: (int)floor (x * 255.0f + 0.5f). WebValid values are 0 through 255. Returns Color The Color that this method creates. Exceptions ArgumentException red, green, or blue is less than 0 or greater than 255.

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))) WebJan 31, 2011 · If I increment a byte past 255 it wraps back to 0, and vice versa for decrementing, presumably because C# actually converts a byte to an int when doing arithmetic on them.
