Pixel graphics are made up of individual pixels, with each pixel representing a digital
the color model used and the quantization.The data volume of a pixel graphic is calculated from the vertical and horizontal resolution multiplied by the quantization. For example, a black-and-white graphic with a resolution of 640 x 480 pixels for Video Graphics Array (VGA) and a color depth of 1 bit ("0" corresponds to black, "1" corresponds to white) has a file size of 38 KB. However, assuming a resolution of 2,048 x 1,536 for Quadruple-XGA (QXGA) and a color depth of 24 bits, or 3 bytes, the uncompressed file size is 9.5 MB
