## Remarks
  
BMP (Bitmap) is a standard image format mainly used on the Microsoft Windows platform. BMP images can range from black and white (1 bit per pixel) up to 32 bit color (16.7 million colors), in that way bitmap image format can store both indexed and true color images. There are two main BMP formats exist: Windows bitmap formats and OS/2 bitmap format. All of these formats supports RLE-type compression for 4 and 8 bits per pixel palette images.
 
BMP files can store only single image per file.
