Digital colors can be represented as a combination of red, green, and blue, with an alpha value specifying how opaque they are. Each value is one byte, and thus in the range of 0 to 255. Instead of having 4 one-byte values, the colors can be stored in one unsigned int of 4 bytes. :
The single number is a sum of the following
1) alpha value multiplied by 16,777,216 2) The red multiplied with 65,536
3) The green multiplied with 256
4) The blue.
Part 1: Write a program that represents the color (128, 255, 128, 64), where the first value is the alpha value, the second value is the next values are the Red, Green and blue. respectively.
Part 2: What are the component values (Alpha, Red, Green, Blue) of a color represented by the combined color value 33554432, using the formula specified for combining color components into a single unsigned integer?"
The formula to represent a color as a single unsigned integer is given as follows:
Combined Color = (Alpha 16,777,216) (Red 65.536) + (Green 256) + Blue
In this formula:
Alpha is the alpha value in the range of 0 to 255.
Red is the red value in the range of 0 to 255. Green is the green value in the range of 0 to 255,
Blue is the blue value in the range of 0 to 255
