A Method of Using Portable Memory Bitmap Graphics Library

Abstract

The invention discloses a transplantable memory bitmap graphics library application method. The method includes the steps that firstly, a memory bitmap graphics library is built based on a basic graphics algorithm and binary data flow in a memory; secondly, related codes of an operation platform are built, and encapsulation is conducted through EngineGraphic; finally, item graphics drawing is finished by the adoption of the memory bitmap graphics library. The efficiency of graphics drawing is higher than the efficiency of graphics drawing through an ordinary platform, the method can be used in large items requiring graphics drawing, so that the technical effect that an item including as many as one hundred thousand even a million lines of codes can be transferred to another platform just by altering fewer codes is achieved.

Description

technical field [0001] The invention relates to the field of computer graphics research, in particular to a method for using a portable memory bitmap graphics library. Background technique [0002] Graphics library plays an important role in computer graphics. With the progress and development of technology, the application of graphics library is becoming more and more extensive. If the project needs to use functions related to graphics drawing, then you need to use platform-related graphics library, such as Windows The MFC library under the WxWidget library, the skia library under the Android platform, and the windml graphics library under the VxWorks platform. And when the project needs to be developed under several platforms at the same time, each version of the code needs to be maintained under each platform, and the calling of the graphics library under each platform is quite different, which increases the maintenance and development of the project. [0003] And when d...

Problems solved by technology

[0006] The invention provides a method for using a portable memory bitmap graphics library, which solves the need to maintain codes of various versions in the graphics library under the existing platform, and the calling of the graphics library under each platform is very different, increasing the The maintenance and development of the project, the technical problem of the graphics library drawing speed is slow, and the efficiency of graphics drawing is higher than that of the general platform. Using this method in large-scale projects that require graphics drawing can make as many as 100,000 or even 100 The technical effect of transferring a project with thousands of lines of code to other platforms only needs to modify a few hundred lines of code
