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): ---------------------------------------------------------------------------- 0 SECTION 2 HEADER 9 $EXTMIN 10 -71.5 20 46.444444444444 30 0 9 $EXTMAX 10 -71.5 20 46.444444444444 30 0 9 $LTSCALE 40 1 0 ENDSEC 0 SECTION 2 TABLES 0 TABLE 2 LTYPE 100 AcDbSymbolTable 0 LTYPE 100 AcDbSymbolTableRecord 100 AcDbLinetypeTableRecord 2 CONTINUOUS 70 0 3 Solid line 72 65 73 0 40 0 0 LTYPE 100 AcDbSymbolTableRecord 100 AcDbLinetypeTableRecord 2 BYLAYER 70 0 3 72 65 73 0 40 0 0 LTYPE 100 AcDbSymbolTableRecord 100 AcDbLinetypeTableRecord 2 BYBLOCK 70 0 3 72 65 73 0 40 0 0 ENDTAB 0 TABLE 2 LAYER 100 AcDbSymbolTable 70 0 0 LAYER 100 AcDbSymbolTableRecord 100 AcDbLayerTableRecord 2 0 70 0 62 7 6 CONTINUOUS 0 ENDTAB 0 ENDSEC 0 SECTION 2 ENTITIES 0 LINE 100 AcDbEntity 8 0 6 CONTINUOUS 48 1 62 256 10 -71.5000 20 46.4444 30 0.0000 11 104.5000 21 109.3889 31 0.0000 0 ENDSEC 0 SECTION 2 OBJECTS 0 ENDSEC 0 EOF ---------------------------------------------------------------------------- THIS IS MY NOT WORKING DXF (line and image): ---------------------------------------------------------------------------- 0 SECTION 2 HEADER 9 $EXTMIN 10 -134.509920634949 20 66.5238095238 30 0 9 $EXTMAX 10 -134.509920634949 20 66.5238095238 30 0 9 $LTSCALE 40 1 0 ENDSEC 0 SECTION 2 TABLES 0 TABLE 2 LTYPE 100 AcDbSymbolTable 0 LTYPE 100 AcDbSymbolTableRecord 100 AcDbLinetypeTableRecord 2 CONTINUOUS 70 0 3 Solid line 72 65 73 0 40 0 0 LTYPE 100 AcDbSymbolTableRecord 100 AcDbLinetypeTableRecord 2 BYLAYER 70 0 3 72 65 73 0 40 0 0 LTYPE 100 AcDbSymbolTableRecord 100 AcDbLinetypeTableRecord 2 BYBLOCK 70 0 3 72 65 73 0 40 0 0 ENDTAB 0 TABLE 2 LAYER 100 AcDbSymbolTable 70 0 0 LAYER 100 AcDbSymbolTableRecord 100 AcDbLayerTableRecord 2 0 70 0 62 7 6 CONTINUOUS 0 ENDTAB 0 ENDSEC 0 SECTION 2 ENTITIES 0 IMAGE 100 AcDbEntity 8 0 6 CONTINUOUS 48 1 62 256 10 44.6111 20 28.7222 30 0.0000 11 0.2292 21 0.1323 31 0.0000 12 -0.2647 22 0.4585 32 0.0000 340 6B 13 394 23 287 340 6B 0 LINE 100 AcDbEntity 8 0 6 CONTINUOUS 48 1 62 256 10 -134.5099 20 66.5238 30 0.0000 11 -19.3810 21 200.7500 31 0.0000 0 ENDSEC 0 SECTION 2 OBJECTS 0 IMAGEDEF 5 6B 100 AcDbEntity 90 0 1 C:\Users\Martin\Desktop\feature17.png 10 394.0000 20 287.0000 11 0.2647 21 0.0000 280 1 281 3 0 ENDSEC 0 EOF ---------------------------------------------------------------------------- I hope somebody can help me.
