int dxf_line_struct::color

Color of the entity.
Defaults to BYLAYER if ommitted in the DXF file.
Note that entities encapsulated in a block with the color BYBLOCK are represented in the "native" color of the BLOCK entity.
Group code = 62.

int dxf_line_struct::graphics_data_size

Number of bytes in the proxy entity graphics represented in the sub-sequent 310 groups, which are binary chunk records (optional).
Group code = 92.

Since:: Introduced in version R2000.

Warning:: On some 64 bit workstations output is generated with group code "160", thus omitting group code "92".
