Graph drawing method and device

Abstract

The invention discloses a graph drawing method and device. The method comprises the steps of: aiming at a pixel point at each position, obtaining a color of a pixel point at a corresponding position of a mask code image corresponding to a to-be-drawn graph according to a plurality of pixel points included in the to-be-drawn graph; and determining whether to draw the pixel point at the position according to the obtained color. Through the mask code image, the to-be-displayed part of the to-be-drawn graph is controlled, the to-be-drawn graph corresponds to the mask code image, if the to-be-drawn graph needs to be changed, the operators only need to update the mask code image, so that graph drawing can be simply and conveniently carried out on a software interface.

Description

technical field [0001] The invention relates to the field of computers, in particular to a graphic drawing technology of a software interface. Background technique [0002] Now the software interface of the computer is very important, and there are more and more controls and pictures showing irregular graphics on the interface, such as pictures of eyes. We need to draw any area in a picture, instead of drawing all the graphics. For example, if figure 1 The rendering effect diagram of the irregular graphics shown, there are figure 1 The picture on the left is eye.bmp, and then we need to draw the eyes inside to the interface to realize figure 1 For the effect shown on the right, only draw the eyes, without any gray background. There are generally two implementation methods commonly used now: [0003] One is to make a rectangular control, and the parts around the eyes in the graphics are drawn in the same color as the background color, so that it looks like only an irregu...

Problems solved by technology

But there is a problem with this, that is, when the background of the interface changes, the white background is displayed again

like image 3 shown figure 2 The effect picture after the background of the middle interface changes, which is very bad

[0004] The other is to draw only irregular graphics in the code according to the image location area in detail when drawing the control, such as figure 1 The eye part in the picture, but this method also has a disadvantage, that is, if you change a picture, the code has to be rewritten, because the content of the irregular area in each picture is different
