BMP file format
Microsoft Photo Editor
BMP – is a popular bitmap file format for storing the scan-line files, presented by Microsoft experts. It is designed exclusively for single-layered scan-lines. Such files are able to have several extensions: .rle, .dib, .bmp. With the built-in support in Windows OS / 2, the extension is seamlessly opened by various applications.
The image is placed with the DIB extension, which implies the ability to determine the pixel's hue in a form that is not related to the color display method. As a result, Windows OS can display a scan-line image on any display device. The BMP files are larger because they contain an uncompressed image.
