When reading the following articles, please pay attention to the conceptual differences between "graphics" and "images" and "drawing" and "painting".
One, two different types of graphics programs
Generally speaking, image editing software refers to the processing of photo-level images, and the image layer composed of continuous tones is rich in color and realistic. These softwares are characterized by coloring pixels, which are called "bitmaps". After the program is started, it will take up a lot of resources, and opening a high-quality picture file will reach tens of megabytes. The reason why bitmap images rely too much on resolution is to keep the information of each point coordinate. Drawing software is used to draw vector graphics, which is suitable for drawing or processing relatively simple basic graphics composed of contour lines, such as the design and production of mechanical graphics. They are described by the function set of the window, and the edges of the graph are smooth and clean. Although the enlargement of vector diagram will not cause distortion, the calculation amount is very large when dealing with complex graphics. We can't simply say who is better or worse in bitmap and vector graphics software. They are aimed at different application fields. Technically, image processing software is designed for bitmap images, while computer graphics is designed for vector graphics. For image editing software, it should have three main functions: photo editing, image combination and painting. The evaluation of drawing software mainly examines its drawing skills and artistry. Today's graphics software is not as strictly differentiated in function as before. Products spanning image editing and drawing software include "Canvas" and "Wright Design" by Deneba. As far as bitmap programs are concerned, vector graphics in the form of paths can also be saved like PhotoShop.
The following table lists the most popular computer drawing software and image editing software for reference.

Second, how to choose bitmap image software
Like Macromedia's Flash/Dreamweaver/Fireworks, Adobe also has its own three sets of vehicles, not only its own fist product PhotoShop, but also its own vector graphics drawing software Illustrator, and another comprehensive typesetting software PageMaker that integrates these two softwares, which arranges bitmaps and vector graphics uniformly to complete high-quality desktop output. After learning one of them, you will quickly master the use of other softwares. These softwares have the same interface and can easily coordinate their work, allowing users to create more exquisite and complex graphics to complete professional drawing, font processing and packaging design. Abundant plug-ins conforming to Adobe standards support multiple programs. With the arrival of PhotoShop6.0, its professional image processing function is even more exciting. The new version strengthens the support for the Internet. Optimization, clipping and animation that were previously completed by calling Image Ready can now be completed directly in the main program.
