Embodiment Construction

[0032] Embodiments of the present invention provide a graphic device display method and a corresponding device. After receiving a graphic device display request, the method and device search to obtain the coordinate information and device type of the graphic device, and then determine the device according to the device type information The four-corner range, and then based on the size of the display screen, the stretched or compressed four-corner range is corrected. After calibration, the graphics device is displayed in the area determined by the four-corner range, which solves the problems caused by the direct display of graphics devices in the prior art. The problem of display ratio imbalance avoids secondary manual adjustment, thereby improving the efficiency of graphics device positioning and display.

[0033] In order to clearly understand the technical solutions and technical features of the present invention, detailed descriptions are given below in conjunction with the ...

Abstract

The embodiment of the invention provides a graph equipment display method. The method comprises the following steps: receiving a graph equipment display request, wherein the graph equipment display request comprises a graph device identification; searching to obtain the coordinate information and device type of graph equipment to be displayed according to the graph device identification; determining the device type of the graph equipment to be displayed; if the graph equipment is point-shaped graph equipment, obtaining a foursquare range value according to preset magnification; if the graph equipment is line-type or surface-type graph equipment, obtaining the maximum value and minimum value of coordinates of the equipment, and determining the foursquare range value of the equipment according to the maximum value and the minimum value of the coordinates; adjusting the foursquare range value of the graph equipment according to the size of a display screen; and displaying the equipment to be displayed in a region determined by the foursquare range values. The embodiment of the invention also provides a graph equipment display method. According to embodiment of the invention, the problem that the proportion is improper when the graph equipment is displayed is solved, and hand regulation is avoided.

Description

technical field [0001] The invention relates to the technical field of graphic display, in particular to a graphic device display method and a corresponding device. Background technique [0002] Graphic display technology is widely used in various fields, especially after the emergence of geographic information system (GIS, geographic information system), the graphic display technology has achieved important development. Geographic information system integrates geographical science, computer technology, remote sensing technology and information science to establish a set of data sets corresponding to the physical world, which are used to guide practical work after analysis, processing and transformation of these data. For example, in the power equipment management system, the widely distributed power equipment is abstracted into models one by one according to the actual situation, and then the actual data of these models are collected, including coordinate data, equipment st...
