c++ - How to parse DXF hatch by means of dxflib -


i using dxflib in order parse dxf files. have implemented class dl_creationadapter

class entityhandler : public dl_creationadapter { public:      /** called every hatch entity. */     void addhatch(const dl_hatchdata& data);      /** called every hatch loop. */     void addhatchloop(const dl_hatchloopdata& data);      /** called every hatch edge entity. */     void addhatchedge(const dl_hatchedgedata& data);  };

but have problem while parsing entities of type hatch. is, not able find data related rounded paths.

considering example following dxf image:

enter image description here

for each dl_hatchedgedata receive dl_hatchedgedata.type equals 0 , list of vertices, able build path following one:

enter image description here

please note difference between 2 images.

where can find information fact conjunctions of path rounded?
