\nIn computer graphics, a bitmap or pixmap is a type of memory\norganization or image file format used to store digital images. The\nterm bitmap comes from the computer programming terminology,\nmeaning just a map of bits, a spatially mapped array of bits. Now,\nalong with pixmap, it commonly refers to the similar concept of a\nspatially mapped array of pixels. Raster images in general may be\nreferred to as bitmaps or pixmaps, whether synthetic or\nphotographic, in files or memory. In certain contexts, the term\nbitmap implies one bit per pixel, while pixmap is used for images\nwith multiple bits per pixel.[1][2]\n\n<\/pre>\n\nMany graphical user interfaces use bitmaps in their built-in\ngraphics subsystems;[3] for example, the Microsoft Windows and OS\/2\nplatforms' GDI subsystem, where the specific format used is the\nWindows and OS\/2 bitmap file format, usually named with the file\nextension of .BMP (or .DIB for device-independent bitmap). Besides\nBMP, other file formats that store literal bitmaps include\nInterLeaved Bitmap (ILBM), Portable Bitmap (PBM), X Bitmap (XBM),\nand Wireless Application Protocol Bitmap (WBMP). Similarly, most\nother image file formats, such as JPEG, TIFF, PNG, and GIF, also\nstore bitmap images (as opposed to vector graphics), but they are\nnot usually referred to as bitmaps, since they use compressed\nformats internally.\n\n<\/pre>\nsource: http:\/\/en.wikipedia.org\/wiki\/Bitmap<\/p>\n","protected":false},"excerpt":{"rendered":"
