Shape template matching based on Halcon learning [9] PM_ multiple_ dxf_ models. Hdev routine -- [read and write XLD from DXF file]

* This sample program demonstrates how to read DXF File and how to use this object CAD Description generate shape model .

Others are similar to the previous blog , Mainly about the use of two operators .
