A bitmap graphic is composed of a grid of tiny rectangular cells called

The color of each cell is stored as a$($n$)$

number. Popular bitmap graphics formats include BMP$,$ TIFF, GIF, JPEG, RAW, and PNG$.$

Both scanners and cameras produce images in bitmap format. Digital display devices represent colors using the color model. Although colors are ultimately represented as bits when a graphic is stored or transmitted, color values can be specified in binary, $,$ or decimal. Color refers

to the number of colors available for use in an image. The dimensions of the grid that forms a bitmap graphic are referred to as its $.$ It is possible to change the resolution and$/$or the file size of a bitmap graphic; but because bitmaps are resolution these changes can reduce image quality. For example, enlarging a bitmap requires your computer to fill in missing pixels, which often results in a jagged or image. Image compression shrinks the size of a graphics file. compression is used for images stored in JPEG format, but compression is used for PNG$,$ GIF, and TIFF files. Photoediting software includes tools, such as an image $,$ that adjusts brightness values for various ranges of pixels. Algorithms for scrub out designated areas of an image and replace the missing pixels. Clipping paths and alpha blending are useful for digital when you want to assemble parts of several photos into one image. Panoramic and $360-$degree images can be assembled using image to match the edges of a sequence of photos. Stereoscopic effects can be achieved with a photo pair or by creating a$($n$)$ with red and blue coloration.
