Image file format
1, JPEG format
JPEG The format is translated as Joint Photographic Experts Group. The JPEG format is both an image format supported by Photoshop and a compression scheme.
Features: It is a storage type commonly used in Macintosh systems. The JPEG format has a good compression ratio. Compared with the LIW lossless compression used by the TIF file format, its compression ratio is larger, but it uses lossy compression, which will lose part of the image data when storing the file. The user can select the final quality of the image before storing, so that You can control the extent of data loss.
2. TIF format
TIF or TIFF (the abbreviation of Tagged Image File Format) format is the tagged image file format. TIF format is the standard image format in the printing industry.
Features: Very versatile, almost all image processing software and typesetting software provide good support for it, so it is widely used for image data exchange between programs and computer platforms.
3. GIF format
GIF is the abbreviation of Graphic Interchange Format. The image in GIF format is relatively small, and it forms a compressed 8-bit image file.
Features: This format is usually used to shorten the loading time of images. When transmitting image files on the network, using GIF format image files is much faster than image files in other formats.
4. EPS format
EPS is the abbreviation of Encapsulaed PostScript. DPS format is a file format that can be exchanged between Illustrator and Photoshop. It is a flow curve and simple graphics produced by Illustrator software. and professional images are generally stored in the EPS file format.
Features: Photoshop can obtain files in this format, and can also store other graphics in EPS format to facilitate the use of Illustrator software for drawing or PageMaker software for typesetting.
5. BMP bitmap format
The most typical program that uses BMP format is Windows Paintbrush. The file is not compressed and takes up a lot of disk space. Its color storage formats are 1-bit, 4-bit, 8-bit and 24-bit.
Features: This format is a format that is widely used today. However, the disadvantage is that the format file is relatively large, so it can only be used on a single machine and is not popular on the network.
6. PCX format
PCX format is a format developed by ZSOFT when developing the image processing software Paintbrush. The storage format ranges from 1 to 24 bits.
Features: It is a compressed format and takes up less disk space. Because the format has been around for a long time and has compression and full-color capabilities, the PCX format is still very popular.
