The BMP File Format, also known as Bitmap Image File or Device Independent Bitmap (DIB) file format or simply a Bitmap, is a Raster graphics image file format used to store bitmap digital images, independently of the display device (such as a graphics adapter), especially on Microsoft Windows and OS/2 operating systems.
The BMP File Format is capable of storing 2D digital images of arbitrary width, height, and resolution, both monochrome and color, in various color depths, and optionally with data compression, alpha channels, and color profiles.
