Design And Implementation Of The SVG Editor For Power Ststem

This article describes the design and implementation of a SVG Editor for power system. The editor can be used to draw electrical wiring graphics. Specific studies include the following aspects:(1) The display, editing, storage and export of SVG graphics. Editor provides a graphical user interface that allows users to draw an electrical wiring diagram quickly and accurately; editor able to save the SVG files in local disk and the database.(2) The import of graphics from other systems.During the import process, layers and symbols are automatically extracted and stored.Meanwhile, in order to take advantage of the original image material for graphic editing, the editor will also able to extract and store symbols and layer information in the import process(3) Establishment and maintenance of user-defined symbol library. Drawing and Storge of custom symbols. Editor provides symbol management functions. And provides functions of editing existing symbols and creating new symbols. In this way, users may easily create and maintain custom symbol library.(4) Establishment and maintenance of user-defined layer library, as well as hiding and locking techniques based on layers. Editor provides layer management functions to manage the imported layes. Also, it supports to hide or lock layers.(5) Data binding. The editor can associate static images with dynamic data, so that the graphics can be refreshed when they are displaying in other systems.
