Even resizing a color image is quite fast. I have another question about the color computer. I've heard that the 16-bit color is 12 bits of color, and four bits of alpha channel. I assume that this means 3 bits each or red, green, and blue, but I'm not sure what the "alpha" is -- some type of transparency effect? Stephen Peters
