Bitmap BMP
It is a kind of image file format which is
independent of hardware devices and widely used. It uses bit mapping storage
format, and does not use any compression except image depth. Therefore, BMP
files occupy a lot of space. The image depth of BMP file can be lbit, 4bit,
8bit and 24bit. When BMP files store data, images are scanned from left to
right and from bottom to top.
Since BMP file format is a standard for
exchanging graph-related data in Windows environment, the graphics and image
software running in Windows environment supports BMP image format.
Typical BMP image file consists of three
parts: bitmap file header data structure, which contains the type of BMP image
file, display content and other information; bitmap information data structure,
which contains BMP image width, height, compression method, and definition of
color and other information.
BMP is (Windows Bitmap) Windows Bitmap can
store a single raster image in any color depth (from black and white to 24-bit
color). Windows bitmap file format is compatible with other Microsoft Windows
programs. It does not support file compression, nor does it apply to Web pages.
Overall, the disadvantages of Windows bitmap file format outweigh its
advantages. In order to ensure the quality of photos and images, please use
PNG, JPEG, TIFF files. BMP files are suitable for wallpaper in Windows.
Advantages: BMP supports 1 to 24 bit color depth.
BMP format is widely compatible with
existing Windows programs, especially older ones.
Disadvantage: BMP does not support
compression, which can result in very large files.
