What is a bitmap image in Photoshop CS6. When we launch Photoshop CS6, We can create an image with fixed width and height size. That file are saved with PSD or BMP file. By this way, you can make a bitmap image. Computers use binary to store data, in which only bits of 0 and 1 are used. A bitmap is a map of bits.
If you want to understand how a bitmap image displays. Frist, you should know the computer display screen. The display is made by “small square” called pixel. Either the pixel will be black or white corresponding 1 or 0. Each pixel in the bitmap might have 16, 24, or 48 bits of information associated with it.
