NAME

image_surface_resolve - Retrieve current image properties in world-space.

SYNOPSIS

proptbl
image_surface_resolve( vid )

DESCRIPTION

Most of the surface_ class of functions return results in object space. This function will traverse the related set of object hierarchies and resolve the world-space ones that will be used when compositing the output.

NOTES

1: The fields used in proptbl are: (x, y, z, width, height, depth, angle, roll, pitch, yaw, opacity and order).
2: this function has a highly variable cost since the rendering pipeline normallys caches both resolved properties and resulting transformation matrices, if possible.

EXAMPLE

function image_surface_resolve0()
      a = fill_surface(32, 32, 255, 0, 0);
      b = fill_surface(64, 64, 0, 255, 0);
      link_image(b, a);
      move_image(a, 100, 100);
      move_image(b, 50, 50);
      props = image_surface_resolve(b);
      print(string.format("%d %d", props.x, props.y));
