DXF syntax for raster image

Recommended Posts

array81

I'm working on a small software. My software must be export a DXF file to work with Autocad.

On my DXF there area lines and a raster image. I'm reading the DXF 2002 reference (I have choose 2002 version for compatibily problems). If I try to export only lines my DXF is read from Autocad (but also other CAD software).

My problem is the raster image. If export the raster image Autocad don't read my DXF.

 

Which are the minimum requirements for creating to add raster image on my DXF?

 

 

THIS IS MY WORKING DXF (only a line):
