The configuration parameters refer to parameters for drawing network elements, and corresponding network elements, which usually include graphic information, color information, and the like of the network elements, can be drawn according to the configuration parameters.
Specifically, the configuration parameters are generally input by a user who needs to draw the network elements, and the user selects the shape, size, and color of the network elements according to the properties of the functions and the like of each device in the power dispatching data network; wherein the shape of the network elements is generally a pie chart (pie or ellipse pie), a cube or a cuboid. In addition, in the power scheduling data network, the network element is generally used to represent a device, and may represent a communication core, a power transmission section, a power supply central station, and the like.
the GDI (Graphics Device Interface) is responsible for information exchange between the system and the drawing program, and handles Graphics and image output of all Windows programs. The GDI is configured with a plurality of functions, and the drawing of a vector graphic can be performed by calling the GDI function, wherein the vector graphic comprises drawing primitives (such as straight lines, curved lines and graphics) specified by a series of points in a coordinate system. For example, a straight line may be specified by its two end points, while an ellipse may be specified by determining the points of its two focal positions and giving a pair of numbers for the major and minor axis lengths. In this embodiment, a vector graphic can be drawn by calling a corresponding function from the GDI according to the graphic information.

Specifically, after the vector graphics are drawn, selecting corresponding colors according to the color information to perform color filling on the vector graphics; in this embodiment, the vector graphics are usually rendered by using the color fill function of the GDI.
In the method for drawing the network elements in the power dispatching data network, firstly, the configuration parameters of the network elements are obtained, the configuration parameters are analyzed to obtain the graphic information and the color information of the network elements, the vector graphics are drawn by adopting a GDI (graphics device interface) method according to the graphic information, and then the vector graphics are subjected to color filling treatment according to the color information, so that the network elements are obtained. According to the drawing method, the vector graphics are drawn by adopting the GDI technology according to the configuration parameters, on one hand, the graphics can be drawn according to the requirements of users or user-defined parameters, and the obtained graphic structure is more flexible and diversified; on the other hand, the GDI technology is utilized during drawing, the drawing process is simpler, and the graphics can be subjected to color filling, so that the network element display mode is more diversified.

In addition, for a network element, the network element can be composed of a single graph or a plurality of graphs which are stacked; when a graphic stack is needed, the position of the graphic stack needs to be known, and usually a certain point of the stacked network elements (i.e. the network elements at the bottom layer) is selected as a stacking point, and then a new network element is stacked with the stacking point as the center. According to the text information and the stacking position information, the text content can be rapidly displayed and stacked on the network element, the modification process is simple and convenient, and the user-defined requirement can be met to the greatest extent.

The DrawText function is to write the formatted text in a specified rectangle and format the text according to a specified method (extended tab, character alignment, broken lines, etc.). By adopting the method, the text content can be conveniently displayed at the designated position in the network element, and the modification is convenient.

The specific process is as follows: and acquiring the Color information of the closed region object and the closed region object of the vector graphics through the GDI, and then performing RGB Color configuration by using the SetValue of the Color function in the GDI, namely finishing the coloring of the specified closed region.
