relink_image(3)			 Arcan Lua API		       relink_image(3)

NAME
       relink_image - Reassign and translate the property-space	to be relative
       another object

SYNOPSIS
       nil
       relink_image( vid:id, vid:newparent )
       relink_image( vid:id, vid:newparent, int:panchor	)
       relink_image( vid:id, vid:newparent, int:panchor, int:anchor_opt	)

DESCRIPTION
       This  function is a specialized variant of link_image , please read the
       documentation for that function for a full  description	of  the	 argu-
       ments.  The  difference	between	the two	is that	this one preserves the
       relative	resolved world-space position between id  and newparent	. With
       link_image , if id  is at 100,100 and newparent	  is  at  100,100  the
       post-link  world	 coordinate of id  will	be 200,200. With relink_image
       the post-link world coordinate will be 100,100 and its local properties
       will put	it at 0,0. This	is rougly equivalent to	resolving id  and new-
       parent  before linking, calculating the	relative  position  difference
       and moving the object to	the new	position.

EXAMPLE
       function	relink_image0()
	     a = fill_surface(64, 64, 255, 0, 0);
	     b = fill_surface(32, 32, 0, 255, 0);
	     move_image(a, 100,	100)
	     move_image(b, 110,	110)
	     relink_image(b, a);
	     show_image(b);
	     blend_image(a, 1.0, 50);
	     move_image(a, VRESW, VRESH, 100);
	     rotate_image(a, 100, 100);
	     expire_image(a, 100);
       end
