Please refer to Fig. 1, one embodiment of the invention provides the method for displaying image in a kind of display system, comprising:
S101: obtain the described real resources node in display system, and retrieve the first object node corresponding with each real resources node;
Resource node described in the embodiment of the present invention represents a storage area in this display system, the data image to be shown that the video driver for storing this display system generates according to display command.Destination node represents that one for showing the physical type of data image to be shown, as VGA (VideoGraphics Array) display end, and DVI (Digital Visual Interface) display end etc.
Resource node in the embodiment of the present invention comprises real resources node and virtual resource node.Real resources node is corresponding with real storage area.Virtual resource node is relative to real resources node, not corresponding with real storage area, but has the attribute of real resources node.
Destination node in the embodiment of the present invention comprises real goal node and virtual target node.Real goal node represents a physical solution code function.Virtual target node relative to real goal node, the physical solution code function do not represented, but there is the attribute of real goal node.
In the embodiment of the present invention, increase virtual resource node and virtual target node are to make the upper strata graphics system (such as microsoft operation system) of described display system increase exercisable resource node.Particularly, can according to virtual resource Node configuration virtual target node.
In the embodiment of the present invention, display system carries out image display by final according to showing paths of being made up of resource node and destination node.For convenience of description, in the embodiment of the present invention, the set showed paths be made up of resource node and destination node is called display topological structure.The foundation of display topological structure can be divided into following step:
First, the resource node in display system inquiry current system and the number of destination node, and according to the resource node inquired and destination node tectonic manifestation topological structure.
It should be noted that, it is real resources node or virtual resource node that display system cannot distinguish a resource node; Also cannot distinguish a destination node is real goal node or virtual target node.So what just there will be in the display topological structure of display system structure that real resources node and virtual target node formed shows paths, or showing paths of being formed by virtual resource node and real goal node.
As previously mentioned, virtual resource node and virtual target node are illegal concerning real display driver and viewing hardware, if have virtual resource node or virtual target node filtered to pass to lower floor in showing paths to drive, system crash will be caused.The method that the embodiment of the present invention provides is exactly in order to avoid during virtual resource node or virtual target node appear at and show paths, and obtains real resources node from resource node.With real resources node for object, retrieve the first object node corresponding with each real resources node further.
S102: determine the first virtual target node from described first object node;
If in this display system, if certain real resources node is only corresponding with a destination node, the quantity of so described first object node is one.This first object node is likely a virtual target node, is also likely a real goal node.In this case, S102 is specially: determine whether described first object node is the first virtual target node.Particularly, if first object node is virtual target node, so this first object node is exactly the first virtual target node; If first object node is real goal node, so for this real resources node, it does not just have the first virtual target node.
Generally, a real resources node may corresponding multiple destination node.Now, multiple destination node is all first object node, and the virtual target node in these first object nodes is exactly the first virtual target node.A corresponding multiple first virtual target node of real resources node possibility, the corresponding first virtual target node of possibility, may not have the first corresponding virtual target node yet.
S103: described first virtual target node is replaced with the first real goal node;
