1。 There are many sources of vector maps, such as cameras, scanners and photocopiers generated by computer software. Vector maps can only be generated by computers.

2。 Commonly used vector graphics software: Adobe Illustrator, CorelDRAW, Adobe Flash, etc.

3. Use of vector diagrams: Basically, the use of all vector diagrams is not the ultimate goal, and vector diagrams are used to help generate bitmaps. Such as printing, engraving, developing, ps processing, etc. , must be exported as a bitmap in advance.

4. Why use vector diagram: In some ways, the advantages of vector diagram are obvious. For example, a cartoon picture, the vector file is much smaller than the bitmap file. The most important thing of vector diagram is that there will be no sawtooth after infinite amplification. And I think another advantage of vector diagram is also very useful, that is, vector diagram has the characteristic of real-time modification.
