1, (1) Vector diagram: Vector diagram, also known as vector diagram, uses a series of computer instructions to describe and record a graph. A graph can be decomposed into a series of subgraphs composed of points, lines and faces. , which records the geometry, line thickness and color of the object.

(2) Bitmaps: Bitmaps are also called bitmaps or pixel maps. The map on the computer screen is made up of luminous points (pixels) on the screen. Each point uses binary data to describe its color and brightness. These points are discrete, similar to a lattice. The tones of multiple pixels form an image, which is called a bitmap.

(3) Pixels: Bitmap images are composed of many points, which are called pixels and are the most basic units of an image.

The main difference between bitmap and vector diagram: In short, from the above description, it can be seen that the scaling of vector diagram at any resolution will not affect its clarity and smoothness. Bitmaps are not. Bitmaps are just pixel maps, and enlarged images will be blurred.
