Hi Even
Ok, done (http://trac.osgeo.org/gdal/ticket/4978).
One thing that I did not do in the patch ( and should probably be done)
is considering the symbology units. I saw that it is possible to query
the unit type of the OGRStylePen. Is it possible to define e.g. the dpi
in the featurestyle such that a driver might convert between pixel / mm?
Regards,
Marco

Hi
I have a question regarding writing the linewith from ogr feature style
in the dxf driver.
In ogrdxfwriterlayer.cpp, linewith is written using code 370. This seems
to work if I open the dxf file with inkscape. However, if I open it with
TrueView (AutoCAD engine), code 370 has no effect on line width.
Furthermore, the application refuses to open a file if the 370 value is
not one contained in
(http://docs.autodesk.com/ACDMAC/2012/ENU/ObjectARX%20Reference/index.html?
frmname=topic&[email protected]).
Looking at a file generated with AutoCAD engine, I see that it uses code
43. Now I'm not a dxf expert at all, so I don't know if it has to do
with different dxf versions or if we should simply change the 370 for 43
in the dxf writer? Shall I provide a patch?
That might be usefull to open a ticket on that with the patch, as well as with
data to reproduce and the file generated by AutoCAD.
Note that my grepping of 370 shows that the DXF reader should likely be
enhanced to recognize code 43 in addition to 370, so that round-tripping
through OGR works.
Note that I don't feel myself as a DXF expert. I may just apply it more or
less blindly it if you are confident in the patch through your testing.
Regards,
Marco
