Vector diagram uses straight lines and curves to describe graphics. The elements of these graphs are points, lines, rectangles, polygons, circles and arcs. , are calculated by mathematical formulas. For example, the vector diagram of flowers is actually the outline of the outer frame formed by line segments. The color of the outer frame and the color surrounded by the outer frame determine the color displayed by the flowers. Because vector graphics can be calculated by formulas, the volume of vector graphics files is generally small. The biggest advantage of vector graphics is that it will not be distorted regardless of enlargement, reduction and rotation; The biggest drawback is that it is difficult to express realistic image effects with rich color levels. Illustrator of Adobe Company and CorelDRAW of Corel Company are the best among many vector graphic design softwares. The animation made by the famous FlashMX is also a vector graphic animation. What's the specific use? According to the form of information, it is divided into vector diagram and bitmap. Vector diagram is a diagram expressed by a series of calculation instructions, so vector diagram is a diagram described by mathematical methods, which is essentially a programming language expression of many mathematical expressions. If the speed of drawing a vector diagram is slow, you can look at the drawing process. You can understand a vector diagram as a "shape", such as a circle, a parabola and so on, so scaling will not affect its quality. A bitmap is a collection of pixels. I don't need an explanation Usage: Vector graphics are generally used to represent relatively small images, which are easy to move, scale, rotate, copy and change attributes. They are usually used to make galleries. For example, many softwares have vector galleries. You can drag them out and draw them as big as you want. *.txt text file *. jpg*。 png*。 Gif image file *.mp3*. Wmv audio file *.MP4*. Avi*。 MKV*。 Flv video file *. Icon Icon Drawing is an image editing program that can be saved as an icon extension. Png format can also be used as icons, but few people use it.
