1, BMP image file format is Microsoft's standard image format for its windows environment. A Windows BMP bitmap is an array of bits opposite to the display pixels. It has two types: GDI bitmap and DIB bitmap.
BMP format supports RGB, index color, grayscale and bitmap color modes, but does not support Alpha channel. The BMP format supports 1, 4, 24 and 32-bit RGB bitmaps.
After five years of painstaking and meticulous work, the joint photo expert group jointly established by the International Organization for Standardization and the International Telegraph and Telephone Advisory Committee put forward the draft proposal of ISO CD 109 18 in March, which is a compression standard suitable for color and monochrome or continuous tone still digital images.
2.TIFF was first introduced by Aldus Company in 1986. It can well support any image from monochrome to 24-bit true color, and it is easy to modify and convert between different platforms.
Different from other image formats, TIFF file has a standard information area to define the image data type, color and compression method stored in the file.
3.GIF is a color image file format with high compression ratio introduced by CompuServe Company in 1980s.
CompuServe Company adopted an efficient lossless data compression method and introduced the GIF image format, which is mainly used for network transmission of image files.
4.PNG file format was proposed and designed by Thomas Boutell, Tom Lane and others. It is an image format designed to adapt to network data transmission, and it is used to replace GIF image format with simple format and strict patent restrictions.
PNG file format supports three main image types: true color image, gray image and color index data image.
