Abstract

The invention is applicable to the image processing field and provides a method for displaying electronic maps, a device and equipment thereof, wherein electronic map data comprises outline information of graphic objects and information of zones which need filling, the method comprises: obtaining the outline information of graphic objects and the information of zones which need filling, drafting and displaying outlines of corresponding figures according to the outline information, filling corresponding graphic objects according to the information of zones which need filling, and displaying the electronic maps after filling. The implement of the invention can provide rich electronic map information with less data processing through drafting the outlines of the graphic objects and displaying preferentially, can provide better visual perception, and can accelerate pre-judgment of users to next operation.

Description

technical field [0001] The invention belongs to the field of image processing, in particular to an electronic map display method, device and equipment. Background technique [0002] Graphics displayed in electronic products such as computers and mobile terminals can generally be divided into two categories: vector graphics and bitmaps. Because vector graphics use straight or curved graphic objects to describe graphics, they are generally small in size and will not be distorted after zooming in, zooming out, or rotating. Therefore, vector graphics are generally used in existing electronic products such as computers and mobile terminals. map. However, a set of electronic maps is as small as covering a village and town, as large as covering the whole country or the whole world, and it includes many graphic objects, which leads to the display on electronic products with low processor computing performance and data bandwidth (such as embedded electronic products). When displayi...
