Is the vector image png or jpg?

In the field of image processing, we often hear the terms vector graphics and bitmaps. They represent two different image representation methods, with their own characteristics and uses. Among these two representation methods, generally speaking, vector images are often saved in SVG, AI, EPS and other file formats, while bitmaps are often saved in png, jpg, bmp and other formats. So to answer the question in the title, vector images can be png or jpg, but they can also be in other formats.

The difference between vector graphics and bitmaps is how they are composed. A bitmap is made up of a series of pixels, each with its own color and position information. Vector graphics are described by geometric shapes and paths, using mathematical formulas to represent images, so they can be infinitely scaled without distortion.

Because of the way vector graphics are constructed, they are suitable for situations where infinite scaling is required while maintaining the clarity and detail of the image. This makes vector graphics widely used in logo design, icon production, illustration drawing and other scenarios. Because vector images can be enlarged infinitely without appearing aliased or pixelated, vector images are often used in designs that require high definition and accuracy.

However, vector graphics also have some limitations. Because vector graphics are described through mathematical formulas, they cannot express continuous color gradients and complex image effects. This makes vector graphics inferior to bitmaps at expressing real-world images such as photos and scenes.

Bitmap is suitable for scenes that need to express complex images, color gradients and image effects. Bitmaps can accurately express the color and position information of each pixel, with higher image realism. Bitmaps also have smaller file sizes, making them suitable for transmission and display on the web.

For bitmaps, png and jpg are two common formats. PNG is a lossless compressed bitmap format that can retain the details and transparency information of the image and is suitable for designing images with transparency effects. In contrast, jpg is a lossy compressed bitmap format suitable for storing images such as photos that require high compression ratios and small file sizes. Although jpg will have a certain loss of image quality, it is not obvious in most cases, so it is more common in network transmission and storage.

To sum up, vector graphics and bitmaps are two different image representation methods, each with its own advantages, disadvantages and applicable scenarios. Although vector images can be in png or jpg format, they are often saved in SVG, AI and other formats. Bitmaps often use png, jpg and other formats, and the specific choice should be determined based on specific needs.
