My friend said that I was very interested in design recently. I said that I saw so many patterns on the Internet and I wanted to design my own picture style. I want to know what formats are available for those pictures on the Internet, and what are the characteristics. I think a lot of friends want to know about this problem, let us study this article together. 1) BMP picture format: The standard bitmap format under Windows system is very common. The structure is simple, uncompressed, and the general image file will be relatively large. Its biggest benefit is that it can be "accepted" by most software and can be called a common format. 2) JPEG picture format: It is also one of the most widely used picture formats. It uses a special lossy compression algorithm to remove the color of the image that is not easily perceived by the human eye, thus achieving a large compression ratio (up to 2: 1 or even 40:1), so "small size, good looks", especially favored by the network. 3) GIF image format: divided into static GIF and animated GIF, support transparent background image, suitable for a variety of operating systems, "body size" is very small, many small animations on the Internet are GIF format. In fact, GIF saves multiple images as an image file to form an animation, so in the end GIF is still the image file format. 4) PSD picture format: The image processing software "Big Brother" Photoshop's special image format, the image file is generally larger. 5) PCX picture format: A format developed by ZSOFT when developing the image processing software Paintbrush, the storage format is from 1 bit to 24 bits. It is a compressed format that takes up less disk space and has the advantages of compression and full color. 6) PNG picture format: (PortableNetworkGraphics portable network graphics) Similar to JPG format, there are many pictures in the web page are this format, the compression ratio is higher than GIF, support image transparency, you can use Alpha channel to adjust the transparency of the image. Guess what you like: png What is the difference between png and gif format pictures? 7) DXF picture format: The special format of 3D model design software AutoCAD, the file is small, the drawing size, angle and other data are very accurate, which is the first choice for architectural design. 8) CDR picture format: the famous graphic design software - CorelDRAW's special format, belonging to vector images, the biggest advantage "weight" is very light, easy to re-process. 9) ICO picture format: ico format is an icon file. Unlike ordinary pictures, it does not support direct viewing in the computer. It is mainly used for the logo icon in front of the website URL. A well-known website has this logo. We will browse the website again. At the time, careful friends will find an icon in front of the URL, this is the ico icon file, as shown below: The above is some of the more common image format introduction, I hope to help computer enthusiasts.
