What are the main image file formats?
PNG pictures store a single raster image at any color depth, and it is a platform-independent format. PNG supports advanced lossless compression and alpha channel transparency. PNG supports gamma correction and interleaving.
Second, JPEG format.
JPEG is lossy, using direct colors and bitmaps. The design goal of JPEG image format is to compress the file size as much as possible without affecting the quality of human distinguishable images. This means that JPEG removes part of the original information of the picture, which is lossy compression.
The advantage of JPEG pictures is that they use direct colors. Because of its richer colors, JPEG is very suitable for storing photos and expressing more vivid image effects, such as color gradient.
3.PDF format is Adobe's electronic publishing software for Windows, UNIX and DOS systems. Like Postseript pages, PDF can contain vector and bitmap graphics, as well as electronic document search and navigation functions.
Four. TIFF format
TIFF stores a single raster image at any color depth. TIFF can be considered as the most widely supported graphic file format in the printing industry. TIFF supports optional compression and is not suitable for viewing in a Web browser.
Verb (abbreviation of verb) BMP format
The abbreviation of BitMap, lossless, supports both index color and direct color, and is a bitmap. This is an old picture format. BMP is lossless, but at the same time, this image format hardly compresses the data, so the image in BMP format usually has a large file size.
