AttachCopyToView( <Object>, <View 0|1|2> )

If View = 0, a copy of given object is created. For View = 1 or View = 2 this command creates a dependent copy of given object whose size in given Graphics View is constant.

例:

Let poly = Polygon((0, 0), (1, 0), (1, 1), (0, 1)).
If Graphics View 1 is active, AttachCopyToView(poly, 1) creates a square with the same size at the same position.

メモ: Once the copy is created, three other arguments are added to the command definition.

AttachCopyToView( <Object>, <View 0|1|2>, <Point 1>, <Point 2>, <Screen Point 1>, <Screen Point 2> )

If View = 0, a copy of given object is created. For View = 1 or View = 2 this command creates a dependent copy of given object whose size in given Graphics View is transformed using the affine transform that maps Point 1 to a point whose screen coordinates (in pixels) are equal to Screen Point 1, and Point 2 to a point with screen coordinates equal to Screen Point 2.

例:

Let poly = Polygon((0, 0), (1, 0), (1, 1), (0, 1)).
If Graphics View 1 is active, AttachCopyToView(poly, 1, (0, 0), (1, 1), (0, 0), (100, 100)) creates a 100px x 100px square in the top left corner of the Graphics View.

メモ: All points of the object are copied, even if they lie outside the view.
