class TextProjector2d from StdSelect inherits Projector from Select2D

	---Purpose: A projector framework specific to texts in 2D views.
    	-- For a string of text, an insertion point and a font, it
    	-- calculates the minimum and maximum points of the text box in the view.

    Pnt2d  from gp,

    Create(aView: View from V2d) returns mutable TextProjector2d;
    	---Purpose: Constructs a 2D text projector framework defined by the 2D view aView.

    Set(me:mutable; aView:View from V2d) is static;
    	---Purpose: Sets the view aView.
    	---C++: inline

    
    Set(me:mutable;atrsf:Trsf2d from gp)is static;
    	---Purpose: Sets the transformation atrsf.
    	-- This transformation is applied to the attachment point
    	-- of the text, and takes the size and length of the text
    	-- into account to give the upper right hand point of the text box.
    	---C++: inline

    	       aPointOut : out Pnt2d from gp) is redefined virtual;
    	---Level: Public 
    	---Purpose: applies the stored trsf to aPointIn to get aPointOut

    	---Purpose:XPos,YPos is the AttachPoint for the text.First, the stored Trsf is
    	--         applied to this point, then we get the size and length of text to
    	--         give the upper point
