What are the two categories of image materials?

Image materials can generally be divided into two categories: one is bitmap; the other is called depiction, vector or object-oriented graphics (images). Bitmaps are also called bitmaps, which are made up of square pixels arranged together. When a bitmap is enlarged, the image will be distorted. The five images mentioned above are all bitmaps. The principles of composing images between vector graphics and bitmaps are different. Its image outline is generated by a function curve. When the image is enlarged, the actual principle is to multiply the curve by a multiple. The image can be easily enlarged without pixel blocks. , there will be no jagged edges on the image.
