Common graphic image file formats are

Common graphic image file formats are as follows:

I. BMP format

Bitmap (foreign abbreviation: BMP, foreign full name: 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. So BMP files take up a lot of space. The image depth of BMP file is 1 bit, 4-bit, 8-bit and 24-bit.

Second, the GIF format

Graphic interchange format (GIF, Graphic Interchange Format) is an image file format developed by CompuServe in 1987. GIF file data is a continuous tone lossless compression format based on LZW algorithm. Its compression ratio is usually around 50%, which does not belong to any application.

Third, 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.

Four. exchangeable image file

Exchangeable image file format (EXIF, full name: exchangeable image file format) 1994 The digital camera image file format advocated by Fuji is actually the same as JPEG format. Besides saving the image data, you can also save the shooting date. Please use exposure information and additional information, such as aperture, shutter, flash data and small images.

The original form of verb (abbreviation of verb)

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, it must be imported into TIFF format with the Twain interface of the imaging software to be processed.
