I tried to use the method “writeImageDef” but when I opened the dxf file with autocad the following error appears: “Unknown object type IMAGEDEF ignored”.

Which are the correct step to do add a background image in a dxf file?

Thanks in advanced for your help.

- Write the image definitions inside the OBJECTS section of the DXF file (see DL\_Dxf::writeObjects / writeObjectsEnd).
- Write the image itself (writeImage) inside the ENTITIES section
