Vector diagram: Generally, the graphics displayed in a computer can be divided into two categories-vector diagram and bitmap. 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 greatest 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 and Corel from Adobe

CorelDRAW of our company is the best among many vector graphic design software. The animation made by the famous Flash MX is also a vector graphic animation.

What is a vector diagram and what is its specific purpose? ; )

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

The purpose is:

Vector graphics are usually used to represent relatively small images. It is easy to move, scale, rotate, copy and change attributes. They are usually used to make galleries. For example, many softwares have a vector library, and you can drag it out and draw it as big as you want.

JPEG: One of the most widely used image formats, it uses a special lossy compression algorithm to delete the image colors that are not easily perceived by human eyes, thus achieving a large compression ratio (up to 2: 1 or even 40: 1), so it is "petite and beautiful", especially favored by the network, and very practical!

BMP: BMP: The standard bitmap format under Windows system, which is widely used. Its structure is simple, without compression, and the general image file will be larger. Its biggest advantage is that it can be "accepted" by most software, which can be called a universal format.

GIF: It can be divided into static GIF and animated GIF. It supports transparent background images and is suitable for various operating systems. Its "body shape" is very small, and many small animations on the Internet are in GIF format. In fact, GIF is to save multiple pictures as a picture file to form an animation, so in the final analysis, GIF is still a picture file format.

Pictures in GIF format can be made by ImageReady, a supporting software of Photoshop.

The conversion can be done by ps or fireworks.
