Abstract

The invention belongs to the technical field of CAD graph conversion, and particularly relates to a method for converting a CAD graph into dot matrix data. The method includes S1, opening graphs and cleaning the graphs, opening a file in a dwg format through a controller; the unrelated items of the map required to be constructed are cleared; S2, setting grating precision;, setting the accuracy ofthe exported grating map; S3, retrieving all graphic data in the dwg file, S4, obtaining point cloud data of all geometric figures, S4, obtaining a point cloud data boundary, gridding a map range according to grid precision, and S5, scanning a grid map from bottom to top and from left to right, and comparing the grid map with the point cloud data to obtain a current grid state; According to the method for converting the CAD graph into the lattice data, the CAD graph is converted into a platform-independent, simple and universal binary graph data format, and the method is good in universality,convenient to read and simple in structure.

Description

technical field [0001] The invention belongs to the technical field of CAD graphics conversion, and in particular relates to a method for converting CAD graphics into dot matrix data. Background technique [0002] Bitmap is composed of more than n pixels, and its concept is mainly relative to the difference between vector graphics. Bitmap and vector graphics are two concepts of modern computer graphics. [0003] Convert the original CAD graphics to dot matrix data, convert CAD graphics to dot matrix data, and generate a simple and common grid map; use GIS software to process or use CAD software to export image files; the above software are all exported to their specific format files Data cannot be generalized. Contents of the invention [0004] In order to solve the problems raised in the above-mentioned background technology. The present invention provides a method for converting CAD graphics into dot matrix data to solve the problem of converting the original CAD grap...
