const field_circles_t & firevision::FieldLines::get_circles ( ) const [inline]

Get circles.

Returns:: reference to a std::list of arcs and/or circles on the field

float firevision::FieldLines::get_field_length ( ) const [inline]

Field length getter.

Returns:: The length of the soccer field

Definition at line 42 of file field_lines.h.

Referenced by firevision::FieldDrawer::draw_field(), firevision::FieldDrawer::draw_line_points(), firevision::FieldDrawer::draw_lines(), firevision::Field::get_field_length(), and firevision::FieldDrawer::get_scale().

cart_coord_2d_t firevision::FieldLines::get_field_offsets ( ) const [inline]

Offset getter.

The field's offset (x,y) is usually zero as the soccer field is symetrically. But in some cases only a part of the field is used and then we need the offset to place the field at the center of a debug image.
