raster image

Raster images or bitmap graphics (e.g., .bmp, .tif, .jpg) are created from a series of pixels to represent graphics. Each pixel in a bitmap image has a specific location and colour value assigned to it.

Bitmap images are resolution-dependent, meaning they represent a fixed number of pixels. As a result, they can appear jagged and lose detail if scaled on-screen or printed at a higher resolution than they were created for.
