#include <ClanLib/display.h>

Construction:

Construct a collision outline.

Attributes:

get_object_bounding_box	Returns the contour used as an object bounding box. (an rotated rectangle)
get_minimum_enclosing_disc	Returns the radius of the outline.
get_inside_test	Returns true if completely-inside test is used.
get_contours	Returns the contours in the outline.
get_translation	Returns the position of the outline.
get_scale	Returns the scaling factor.
get_angle	Returns the rotation angle.
get_width	Returns the width of the image this outline was created from.
get_height	Returns the height of the image this outline was created from.
get_alignment	Get the translation origin and hotspot of the outline.
get_rotation_hotspot	Get the rotation hotspot of the outline.
get_collision_info	Return the info about the collisions. (collision points, normals, pointers to contours, and indexes to lines that intersected)
get_collision_info_state	Fetch the state of the collision testing variables.
resource	Resource owning this outline, if any.

Operations:

operator =	Assignment operator
optimize	Optimize the outline by removing redundant points.
draw	Draw outline on graphic context.
draw_sub_circles	Draw the subcircles surrounding the linesegments on graphic context.
draw_smallest_enclosing_disc	Draw the disc enclosing the entire outline.
set_alignment	Set the translation hotspot of the outline.
set_rotation_hotspot	Set the rotation hotspot of the outline.
set_translation	Set the position of the outline.
set_scale	Set the scale of the outline.
set_angle	Set the angle (in degrees) of the outline.
rotate	Rotate the outline by angle (in degrees).
set_inside_test	Set to true if completely-inside test should be done
enable_collision_info	Enable collision info gathering.
set_collision_info	This will set the collision info of the outline
clean_collision_info	This will empty the collision-info vector
calculate_radius	(Re)calculate the radius of the outline.

calculate_smallest_enclosing_discs	(Re)calculate the smallest circles enclosing every contour in the outline.
calculate_convex_hulls	(Re)calculate the convex hull for every contour in the outline
save	Write the outline to a file.
collide	Returns true if outlines overlap
calculate_penetration_depth	Will calculate the penetration_depth and penetration_normal for all colliding contours.
point_inside	Returns true if a point is inside the outline.
