| | Raster graphics |
 | | A raster graphics image, digital image, or bitmap, is a data file or structure that consists of a generally rectangular array of pixels, or points of color, on a computer monitor, paper, or other display device. |
 | | In 3D computer graphics, the concept of a flat raster of pixels is sometimes extended to a three dimensional volume of voxels. |
 | | A bitmap corresponds bit for bit with an image displayed on a screen, probably in the same format as it would be stored in the display's video memory or maybe as a device independent bitmap. |
