2. WHAT IS BMP FILE?
The .bmp file extension is given to raster image files,
also known as bitmap image files. These non-
compressed image files contain a file header and the
pixels of the associated bitmap.
The file header contained in the BMP file includes
information about the size of the BMP file, the width,
the height, the color options of the BMP image as well
as information about where the bitmap pixels should
be located within the grid.

height and width. These images can be both color images
and monochrome images of various depths.
