png is not a vector image format; the png format refers to portable network graphics, a bitmap format that uses a lossless compression algorithm, and vector images generally refer to image files drawn with drawing software or vector tools , also called an object-oriented image or a drawing image, is mathematically defined as a series of points connected by lines.

Pictures in png format are not vector graphics. Vector pictures generally refer to picture files drawn with vector tools (such as pen tools, path tools, etc.) using drawing software such as illustrater, corelDRAW, etc. You can zoom in or out during editing without losing pixels. A vector image is composed of points linked together. It is an image drawn based on geometric characteristics and has nothing to do with the resolution of the bitmap. Therefore, the picture will not be distorted after being enlarged, and there will be no bitmap mosaic appearance, which means that the picture can be enlarged infinitely.
PNG is not a vector image.
Vector graphics, also known as object-oriented images or drawing images, are mathematically defined as a series of points connected by lines. Graphic elements in vector files are called objects. Each object is a self-contained entity with properties such as color, shape, outline, size, and screen position.
Vector graphics are drawn based on geometric characteristics. A vector can be a point or a line. Vector graphics can only be generated by software. The file takes up less internal space because this type of image file contains independent Separate images and recombine them freely and without restrictions.
Its characteristic is that the image will not be distorted after magnification and has nothing to do with resolution. It is suitable for graphic design, text design, some logo design, layout design, etc.

Characteristics of vector graphics
Same resolution Rate-independent
A vector graphic can be moved and changed multiple times while maintaining its original clarity and curvature, without affecting other objects in the legend. These characteristics make vector-based programs particularly suitable for illustration and three-dimensional modeling, since they often require the ability to create and manipulate individual objects. Vector-based drawing is resolution independent.
The difference between vector graphics and bitmaps
The biggest difference between vector graphics and bitmaps is that they are not affected by resolution. Therefore, when printing, graphics can be enlarged or reduced arbitrarily without affecting the clarity of the image, and can be displayed on the output device at the highest resolution.
Features
#In addition, the most obvious feature of vector graphics: the color edges and line edges of vector graphics are very smooth , For example, if a curved line is uneven, then this kind of vector image is of poor quality. A color block with many small patches of color is also of poor quality. High-quality vector images should be.
Whether you zoom in or out, the edges of the colors are very smooth and clear. The lines are in the same proportion and thickness, and the nodes are also very few. Generally speaking, vectors Pictures are all drawn by bitmap imitation. First there is a picture, and then it is drawn based on its imitation.
