The difference between graphics and images

First, the difference between storage methods: the function of graphics storage drawing; The image stores the position information, color information and gray information of pixels.

Second, the difference between scaling: the graphics will not be distorted when scaling, and can adapt to different resolutions; When the image is enlarged, it will be distorted. It can be seen that the whole image is composed of many pixels.

Third, the difference of processing methods: for graphics, we can rotate, distort and stretch; For images, we can enhance the contrast and detect edges.

Fourth, the difference between algorithms: for graphics, we can use geometric algorithms to deal with them; For images, we can use filtering and statistical algorithms.

5. Others: graphics do not exist subjectively, but are formed subjectively according to objective things; Image is a true description of objective things.
