Bitmap is a type of image file format or memory organization that has used to keep digital images. The term bitmap has been derived from the computer programming terminology that means a map of bits. Now, it is usually refer to the same concept of a spatially mapped array of pixels. Also, the raster images can also be used to refer the bitmaps. However, in some certain contexts the word bitmap has implied for one bit per pixel.
There are numbers of graphical users applying the bitmap in order to design the graphic subsystems. Keep in mind that bitmap is usually merge with a color depth such as 1, 2, 4, 8, to 64bits per pixels. Each bits are representing the bitmap pixels and it can be packaged or unpacked that is fully depending on the device requirements. Before using the bitmaps, you need to consider the color depth, per pixels in the picture that will engage at least in 8bytes. Lots of graphical user interfaces make use of bitmaps in the built in graphics subsystems; example, OS/2 and Microsoft Windows platforms’ GDI sub system, where specific format that us used is OS/2 and Windows bitmap file format, generally named with file extension of .BMP. In addition to, BMP, some other file formats, which store the literal bitmaps also include InterLeaved Bitmap, Portable Bitmap, X Bitmap, as well as Wireless Application Bitmap. In the same way, other image formats, like PNG, JPEG, TIFF, as well as GIF, store the bitmap images (like opposed to the vector graphics), however they are not generally referred as the bitmaps, as they make use of compressed formats. In the typical uncompressed bitmaps, the image pixels are normally stored with the color depth of 1 4 8 16 24 32 48 and 64 bits every pixel.
