Method and device for rapidly generating vector diagram

Abstract

The invention discloses a method and a device for rapidly generating a vector diagram. The method comprises the following steps of: importing a drawn picture and acquiring the data information of the picture, wherein the data information comprises the picture size of the picture; performing scanning to search for pixels meeting preset conditions in a picture area; and generating a path object according to the position information of the pixels meeting the preset conditions, and drawing the generated path object. In the scheme of the invention, the drawn picture is imported, the pixels meetingthe preset conditions are found out of the picture area, the path object is generated according to the position information of the pixels and the generated path object is drawn, thereby generating the vector diagram corresponding to the drawn picture. The vector diagram corresponding to the drawn picture can be generated only by importing the drawn picture without the drawing of a special drawer and special vector graph drawing experiences so as to ensure high generation speed, low workload and low cost.

Description

technical field [0001] The invention relates to the technical field of computer graphics, in particular to a method and device for rapidly generating vector graphics. Background technique [0002] With the development of science and technology, the application of computer is becoming more and more popular, and the application of computer in teaching, education, fire protection and other industries is also becoming more and more extensive. In the application of computers in these industries, many vector graphics will be involved. Applications, these vector graphics include regular vector graphics and irregular vector graphics, such as vector icons used in the fire industry such as fire trucks, sprinklers, and airplanes, basic geometric graphics in the education industry, and some irregular graphics used in the education process, etc. Wait. How to quickly produce vector graphics that can change colors and can be enlarged without distortion, software developers need to design ...

Problems solved by technology

How to quickly create vector graphics that can change colors and can be enlarged without distortion? Software developers need to design and program different graphics. As the number of graphics increases, the cost of coding is higher, and the cost is also higher.

[0003] In the existing ways of drawing or generating vector graphics, one of the ways is to directly use graphics software to draw the vector graphics. However, although this kind of drawing process is convenient and fast, it needs professional producers to make it, and The line color, thickness and closed area filling color cannot be changed. Another existing method is to generate vector graphics by software designers and developers through programming, which can change the line color, thickness and closed area filling color, but the workload is heavy , high cost, and not easy to expand
