The common graphic image file formats are as follows:
1. BMP format
BitMaP (foreign language: abbreviation of BMP, foreign language: full name of bitmap) BMP is an image file format that has nothing to do with hardware devices and has been widely used. It uses bitmap storage format and does not use any compression method except optional image depth. Therefore, BMP files take up a lot of space. The image depth of BMP file is 1bit, 4bit, 8bit and 24bit.
ii. GIF format
the graphic exchange format (foreign language: GIF, foreign language: graphic exchange format) is an image file format developed by CompuServe in 1987. GIF file data is a lossless compression format of continuous tone based on LZW algorithm. Its compression ratio is usually around 5%, and it doesn't belong to any application.
3. UFO format
It is a special image format of the famous image editing software Ulead Photolmapct, which can completely record all the image attributes processed by PhotoMapCT. It is worth mentioning that UFO files use objects instead of layers to record image information.
iv. EXIF format
Exchangeable image file format (short for EXIF, full name: Exchangeable image file format) The image file format of digital camera advocated by Fuji in 1994 is actually the same as JPEG format. In addition to saving image data, it can also be stored at the shooting date. Please use exposure information and attached information, such as aperture, shutter, flash data and small image.
v. RAW format
this is a lossless compression format. Its data is the original file that the camera has not processed, so its size is slightly smaller than TIFF format. Therefore, after uploading to the computer, you must use the Twain interface of the imaging software to be processed to import it into TIFF format.
