Abstract

The invention provides a graph drawing method and device. The method comprises the following steps: background color values of all points to be drawn in a current row in a graph to be drawn are written in a drawing buffer area, the color values of the points to be drawn in the current row are subjected to batch hybrid processing operation, color values of points related to the points to be drawn are subjected to batch hybrid processing operation, batch hybrid processing operation results are written in the drawing buffer area, and color values in the drawing buffer area are subjected to batch drawing operation. Via the method disclosed in the invention, non-continuous memory access is prevented, CPU performance is improved, and graph drawing efficiency is greatly improved due to batch drawing operation.

Description

technical field [0001] The invention relates to graphics processing technology, in particular to a graphics drawing method and device. Background technique [0002] When developing application programs, graphics development is usually involved. At present, various graphics development tools have emerged, such as QT development tools, which can be used for graphics development involved in various applications. [0003] In the prior art, in order to eliminate the concave-convex aliasing that appears on the edge of the picture output by the display, when the graphics development tool draws graphics, it usually needs to render the points around the point every time it is drawn, specifically, by accessing memory The way to update the pixel information of the points around the point stored in the memory, so non-sequential memory access is required. [0004] However, discontinuous memory access when using the existing technology to draw graphics will lead to a decrease in the perf...
