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. However, my professor specifically asks that once a channel reaches its maximum or minimum value that it stays there if the user tries to go out of these bounds. WebOct 26, 2010 · for an 8-bit integer, a value range between 0 and 255 is possible (or -127..127 if it's signed, and in this case, the first bit decides the polarity) for an 8-bit character, it will most likely be an ASCII character, of which is usually referenced by an index specified with a hexadecimal value, e.g. FF or 0A.

Quads have greater … 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).
