C# int 0 255
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.

However, if you need an array of say 100,000,000 consecutive numbers then you should look at a design where you don't have to keep all the numbers in an array to avoid the impact of the memory requirement. 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).
