Abstract

The present application relates to the technical field of industrial data processing, in particular to a PDF drawing vector review method and system based on XG technology, comprising: receiving a PDF drawing data stream through an XG secure communication channel, converting it into a standardized graphic primitive containing two-dimensional coordinates and engineering metadata using a sandbox security parser; and based on this, constructing a spatial semantic data structure integrated with quadtree spatial indexing and semantic grouping information. The present application also constructs a dynamic performance benchmark test data model; when rendering, the optimal rendering scheme that can meet the preset target performance is predicted and selected based on the model, and the data structure is used to efficiently generate an interactive graphic review interface, and finally receive and store user review instructions associated with graphic objects. The present application realizes high-performance and safe vectorization interactive review of PDF drawings in the XG environment by constructing an adaptive rendering model and a data structure that integrates spatial and semantic information.
