Abstract

The embodiment of the invention provides a graph drawing engine and an implementation method of the graph drawing engine. The method comprises the steps as follows: extracting drawing function information of a first graphics device interface and a second graphics device interface; encapsulating the first graphics device interface and the second graphics device interface into a graph drawing engine interface; defining a member function of the encapsulated graph drawing engine interface according to the extracted drawing function information, and calling for the first graphics device interface or the second graphics device interface to fulfill the drawing function corresponding to the member function through the graph drawing engine interface. The graph drawing engine provided by the invention has the advantages of high drawing efficiency, few occupied CPU (central processing unit) resources, good compatibility and interface usability.

Description

technical field [0001] The invention relates to graphics processing technology, in particular to a graphics rendering engine and its implementation method. Background technique [0002] At present, under the Windows operating system, most application programs with a graphical interface require a dedicated graphics device interface to draw them. [0003] Except for games, most applications use GDI (Graphics Device Interface, Graphics Device Interface) and GDI+ to draw their graphical interfaces. The basic principle of GDI drawing is the operation and copying of pixels in the memory. Users can use the many functions provided by GDI or GDI+ to easily output graphics, text and other operations on the screen, printer and other output devices. The emergence of GDI and GDI+ enables programmers to convert the output of the application program into the output on the hardware device without caring about the hardware device and device driver, which realizes the isolation between the p...
