What are the storage formats (more than five) of graphics and image data, and what are their characteristics and uses respectively? I. BMP image file format

BMP is an image file format independent of hardware devices, which is widely used. It uses bitmap storage format and does not use any other compression except the optional image depth.

A typical BMP image file consists of three parts: a bitmap file header data structure, which contains information such as the type and display content of the BMP image file; Bitmap information data structure, including BMP image width, height, compression mode, defined color and other information.

Second, the PCX image file format

PCX is the earliest file format that supports color images, and now it can support 256 colors at most, as shown in Figure 4-25, which displays 256-color images. PCX designers introduced the color image file format with foresight, making it a very popular image file format.

PCX is the image file format of PC brush. The image depth of PCX can be selected as 1, 4 and 8 bits. Because this file format appeared earlier, it does not support true color. PCX file adopts RLE run coding, and the compressed image data is stored in the file body. Therefore, when the collected image data is written into PCX file format, RLE coding should be carried out; When reading the PCX file, it should be RLE decoded before further display and processing.

Three. TIFF image file format

TIFF(TaglmageFileFormat) image file is a common image file format developed by Aldus and Microsoft for desktop publishing system. TIFF format is flexible and changeable. It defines four different formats: TIFF-B is suitable for binary images, TIFF-G is suitable for black and white gray images; TIFF-P is suitable for color images with palette; TIFF-R is suitable for RGB true color images.

TIFF is one of the most complex image file formats, which is extensible, convenient and modifiable, and can be provided for running and image editing programs in IBMPC and other environments.

Four. GIF file format

GIF(GraphicsInterchangeFormat), which means "image interchange format", is an image file format developed by CompuServe in 1987. The data of GIF file is a continuous tone lossless compression format based on LZW algorithm. Its compression ratio is generally around 50%, which does not belong to any application. At present, almost all related software supports it, and a large number of software in the public domain are using GIF image files.

GIF decoding is faster, because interlaced GIF images can be divided into four scans when decoding and displaying. Although the first scan only showed one-eighth of the whole image, and the second scan only showed 1/4, it has already shown an overview of the whole image. When displaying GIF pictures, staggered pictures will make you feel that its display speed seems to be faster than other pictures, which is the advantage of staggered storage.

Verb (abbreviation of verb) JPEG file format

JPEG is the abbreviation of JointPhotographicExpertsGroup Group, and the file is named ". Jpg "or" Jpeg ",which is the most commonly used image file format and lossy compression format. It can compress the image into a small storage space, and the repeated or unimportant data in the image will be lost, so it is easy to destroy the image data.

JPEG format is widely used, especially on the Internet and CD-ROM. At present, all kinds of browsers support JPEG as the image format, because the file size of JPEG format is small and the download speed is fast.

Sixth, TGA format

Tga format (TaggedGraphics) is an image file format developed by American Truevision Company for its graphics card. The file suffix is ". TGA "has been accepted by the international graphic and image industry. TGA has a simple structure, belongs to the general format of graphics and image data, has great influence in the field of multimedia, and is the preferred format for converting computer-generated images into TV.

The biggest feature of TGA image format is that it can make irregular shapes of graphics and image files. Generally, graphics and image files are square. If there are circular, diamond or even empty image files, TGA can come in handy! TGA format supports compression and uses lossless compression algorithm.

Seven. exchangeable image file

EXIF format is a digital camera image file format advocated by Fuji Company in 1994. In fact, it is the same as JPEG format. The difference is that it can also store exposure data such as shooting date, aperture, shutter and flash data, incidental information and small-size images.

Eight, PSD file format

This is a special file format of Photoshop image processing software. The file extension is. Psd can support various image features of layers, channels, masks and different color modes. It is an uncompressed original file storage format. Scanners cannot directly generate files in this format. PSD file sometimes has a large capacity, but because it can retain all the original information, it is the best choice to save the unfinished image in PSD format in image processing.
