Bitmaps consist of individual points called pixels (picture elements), which can be arranged and colored differently to form patterns. When you enlarge the bitmap, you can see the pixels bit by bit, so the enlarged picture will be distorted. However, if viewed from a distance, the colors and shapes of bitmap images look continuous.

A vector diagram is mathematically defined as a series of points connected by lines. The vector can be a point or a line, so that the amplification will not be distorted, but the vector diagram can only be generated by software.

Characteristics of vector diagram

Independent of resolution

The 1. vector graph can move and change its properties many times, while maintaining its original clarity and curvature without affecting other objects in the legend. These characteristics make vector-based programs especially suitable for legend and three-dimensional modeling, because they usually require the ability to create and manipulate a single object. Vector-based drawing is independent of resolution.

2. Difference from bitmap

The biggest difference between vector diagram and bitmap is that it is not affected by resolution. Therefore, when printing, the graphics can be enlarged or reduced at will without affecting the clarity of the drawing, and can be displayed on the output device with the highest resolution.

3. Characteristics

In addition, the most obvious feature of vector diagram is that the color edge and line edge of vector diagram are very smooth. Such as an arc.

4. Freedom and convenience

Vector graphics can be filled with colors freely and conveniently.
