Defaults to BYLAYER if ommitted in the DXF file.
Group code = 6.

Definition at line 69 of file arc.h.

Referenced by dxf_arc_free(), dxf_arc_get_linetype(), dxf_arc_read(), and dxf_arc_set_linetype().

Defaults to 0.0 if omitted in the DXF file, or prior to DXF version R12, or DXF_FLATLAND equals 0 (default).
Group code = 38.

Deprecated:: As of version R11.

Definition at line 77 of file arc.h.

int dxf_arc_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_arc_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".
