Embodiment 1

[0058] Such as image 3 As shown, the present invention discloses a method for drawing a plane vector diagram based on a picture as a background. The system of this solution includes 5 modules, namely a vector layer processor, a background layer processor, a screen operation capturer, a function selector, The layer linkage, through the cooperation of these five modules, invented a double-layer overlay drawing method, which solves the problem of low efficiency and frequent missing drawings caused by the existing parallel drawing method.

[0059] The method of drawing a flat vector diagram based on a picture as a background, especially involving a vector layer display and an image layer display, the two layers are generally superimposed and displayed in a linked or independent manner.

[0060] The functions of the five modules are as follows. Vector layer processor: Responsible for displaying and controlling the flat vector diagram, such as: displaying the flat vector diagram or not d...

Embodiment 2

[0067] Such as Figure 1-2 As shown, the realization method of the technical realization scheme of the method of drawing a plane vector diagram based on a picture as a background includes two parts: the sequence control of drawing and the synchronous control of drawing.

[0068] The first part is the sequence control of drawing.

[0069] If it is drawn in a 2D coordinate system, the drawing order of the background layer processor and the vector layer processor is controlled by the drawing order flag, that is, the drawing order flag is set to: the background layer processor draws first, and the vector layer handles Draw after the device; to achieve the superimposition effect of the bottom layer as the background layer and the upper layer as the vector layer.

[0070] If it is drawn in a 3D coordinate system, you first need to determine whether the depth detection function switch is turned on. If it is turned on, use the visual distance control, that is, draw the vector layer on the f...

Abstract

The invention discloses a system and a method for drawing a plane vector diagram based on an image as a background, and belongs to the field of drawing. In view of the problem in the prior art that the existing mode of drawing based on parallel alignment has the disadvantages of low efficiency, frequent missing, high cost and complex process, the invention provides a system and a method for drawing a plane vector diagram based on an image as a background. The system comprises a vector layer processor which is responsible for displaying and controlling a plane vector diagram, a background layer processor which is responsible for displaying and controlling pictures or images, a screen operation capture device which is responsible for capturing coordinate information in the moving process of a finger on the screen and transmitting the information to a layer linkage device, a function selector which is responsible for recording the mode of operation on a layer at a specific time, and the layer linkage device which is responsible for controlling the drawing order and the image change. The system and the method can ensure high drawing efficiency, and are convenient, simple, and low in cost.

Description

Technical field [0001] The invention relates to the field of drawing, and more specifically, to a system and method for drawing a flat vector diagram based on a picture as a background. Background technique [0002] Vector graphics are drawn based on geometric characteristics. The vector can be a point or a line. Vector graphics can only be generated by software. The file takes up less internal space, because this type of image file contains independent separate images, which can be free Restricted recombination. Its characteristic is that the image will not be distorted after magnification, has nothing to do with the resolution, and is suitable for graphic design, text design and some logo design, layout design, etc. [0003] In the field of architectural design, people need to draw a large number of flat vector diagrams. The current way of drawing a plane vector diagram is generally: put the reference picture aside, and draw the picture while comparing it. This is the drawing m...
