Different Image Types according to Bit Depth

June 24, 2008
An image of each type is opened in Scilab to get their pixel size and bit count - one for binary, one for grayscale, one for true color, and one for indexed image. Since most of the internet files are saved as JPEG. They were converted to other image types using Paint.
