What is a raster to vector conversion?
什么是光栅到矢量的转换？
The process of image conversion from raster to vector is called image vectorization. It is a complex computational process that converts a bitmap image made up of pixels into a vector image made up of lines, curves, and other geometric shapes.
图像从光栅到矢量的转换过程称为图像矢量化。这是一个复杂的计算过程，它将由像素组成的位图图像转换为由线条、曲线和其他几何形状组成的矢量图像。
