Chaithanya, Ahhh that explains it ! Thanks a lot. By the way where do I find out these information (like DXF driver doesn't support style table), as in where is it documented ?
And can you suggest me some other vector format that OGR loads by default, which has style information ? I was using SHP till now, but then it doesn't have the style information at all right. Also it will be great if you can point me to some place where I can find some free samples as well.
