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. WebNov 5, 2010 · I want only 1 byte output for 255 to be the hex value 0xFF in binary. This example shows what I am trying to do to produce a single byte …
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)))
WebJul 30, 2011 · If using floor (), the only value that produces 255 is Integer.MAX_VALUE itself. This distribution is uneven. If using round (), 0 and 255 will each get hit half as many times as 1-254. Also uneven. Using the scaling method I mention above, no such problem occurs.
