Detailed Description

Reading and writing of DXF files.

This class can read in a DXF file and calls methods from the interface DL_EntityContainer to add the entities to the contianer provided by the user of the library.

It can also be used to write DXF files to a certain extent.

When saving entities, special values for colors and linetypes can be used:

Special colors are 0 (=BYBLOCK) and 256 (=BYLAYER). Special linetypes are "BYLAYER" and "BYBLOCK".

Parameters:

dw	DXF writer
data	Entity data from the file
attrib	Attributes

void DL_Dxf::writePolyline	(	DL_WriterA &	dw,
		const DL_PolylineData &	data,
		const DL_Attributes &	attrib
	)

Writes a polyline entity to the file.

Parameters:

dw	DXF writer
data	Entity data from the file
attrib	Attributes

See also:: writeVertex

void DL_Dxf::writePolylineEnd ( DL_WriterA & dw )

Writes the polyline end. Only needed for DXF R12.

void DL_Dxf::writeSolid	(	DL_WriterA &	dw,
		const DL_SolidData &	data,
		const DL_Attributes &	attrib
	)

Parameters:

dw	DXF writer
data	Entity data from the file
attrib	Attributes

See also:: writeControlPoint

void DL_Dxf::writeStyle ( DL_WriterA & dw )

Writes a style section. This section is needed in VER_R13. Note that this method currently only writes a faked STYLE section to make the file readable by Aut*cad.
