Two-dimensional graphic file parsing drawing system and two-dimensional graphic file parsing drawing method

Abstract

The invention provides a two-dimensional graphic file parsing drawing system and a two-dimensional graphic file parsing drawing method, and the two-dimensional graphic file parsing drawing system and the two-dimensional graphic file parsing drawing method are applied to a computer which comprises a storage device and a display device. The two-dimensional graphic file parsing drawing method includes the steps that a two-dimensional graphic file is read from the storage device, and the contents of the file are stored in a file array in a row form; a two-dimensional object array is created, and image elements of all two-dimensional graphic objects in the file array are added into the two-dimensional object array; group code values relevant to two-dimensional graphic object group codes are parsed from the file array; all the two-dimensional graphic objects are parsed from the two-dimensional object array; a graph outline normal vector corresponding to each two-dimensional graphic object is computed; and all the two-dimensional graphic objects and the corresponding graph outline normal vectors are displayed on the display device. By means of the two-dimensional graphic file parsing drawing system and the two-dimensional graphic file parsing drawing method, drawing exchange format (DXF) two-dimensional measurement graphic files can be parsed, the graphic elements can be extracted quickly for being optimized and preprocessed, and a two-dimensional measurement graph provided with the graph outline normal vectors can be drawn.

Description

technical field [0001] The invention relates to a graphics file processing system and method, in particular to a two-dimensional graphics file analysis and drawing system and method. Background technique [0002] At present, in the independently designed CAD system, there is no function of directly importing two-dimensional measurement graphic files in DXF format, and it is impossible to analyze and read graphic elements, such as points and lines, for two-dimensional measurement graphic files in DXF format. , circle, etc. Although there is already a 2D conversion system for DXF format measurement graphics files on the market, this 2D conversion system cannot open, import or use DXF format 2D measurement graphics files in the self-developed CAD system, it must rely on other The software converts the object model into a usable type before it can be used, resulting in an increase in cost, and cannot optimize the processing of DXF two-dimensional graphics files.
