What are the picture formats

1, JPG (JPEG) format picture

The most commonly used picture format, the most extensive use. A JPEG picture stores a single raster image in 24-bit color. JPEG is a platform-independent format that supports the highest level of compression, although this compression is lossy. An asymptotic JPEG file supports interleaving. The file is small and the image quality does not change with compression.

2, BMP format Picture

BMP (full name bitmap) is a standard image file format in the window operating system, which can be divided into two categories: device-related bitmap (DDB) and device-independent bitmap (DIB), which is very widely used. It uses bit-mapped storage format, in addition to image depth optional, no other compression, therefore, BMP files occupy a large space. Can be compatible with a lot of software.

3, GIF format picture

GIF is a lossless compression format for continuous tones based on the LZW algorithm. Its compression rate is generally around 50%, it does not belong to any application. At present, almost all of the relevant software support it, the public domain has a large number of software in the use of GIF image files. It is generally possible to make some simple animation effects.

4, PSD format picture

I believe we all attribute Photoshop software, and PSD format is the special format of PS. PSD can store RGB and CMYK mode, but also the PS production process layer, channel, path information to save. However, the PSD format file is large and bitmap mode.

5, PNG format picture

is a bitmap file (bitmap file) storage format, read as "Ping." When PNG is used to store grayscale images, grayscale images can be as deep as 16 bits, and when storing color images, color images can be as deep as 48 bits and can store up to 16 bits of alpha channel data. PNG uses a lossless data compression algorithm derived from LZ77. It is generally used in Java programs, or in Web pages or S60 programs because it is compressed to a high ratio and produces small file sizes.

6, PCX format picture

PCX is an image file format developed by ZSoft in Georgia, originally the company's PC Paintbrush software file format (PCX represents PC Paintbrush Exchange), but it has become one of the most widely accepted DOS image standards, However, this use format has been replaced by other, more complex image formats such as GIF, JPEG, and PNG. Fewer users are using the PCX format to save pictures.

7, DXF format picture

This kind of picture format is AutoCAD software special format. It is a CAD data file format developed by Autodesk Company for CAD data interchange between AutoCAD and other software. DXF is an open vector data format, which can be divided into two types: ASCII format and binary format; ASCII has a good readability, but occupies a larger space, the binary format occupies a small space, fast reading speed.

8, CDR format picture

This is the abbreviation of CorelDRAW, the special format of CorelDRAW software. File is small, vector graphics, aspect processing,

9, of course, there are TIFF, TGA, UFO, EPS, AI, Raw, EXIF, FPX, SVG and other picture formats. This will not be introduced, the above examples are all the same very common picture format.
