Detailed Description

represent 2D affine transformations

This class is used to represent a vtkAffineWidget. This representation consists of three parts: a box, a circle, and a cross. The box is used for scaling and shearing, the circle for rotation, and the cross for translation. These parts are drawn in the overlay plane and maintain a constant size (width and height) specified in terms of normalized viewport coordinates.

The representation maintains an internal transformation matrix (see superclass' GetTransform() method). The transformations generated by this widget assume that the representation lies in the x-y plane. If this is not the case, the user is responsible for transforming this representation's matrix into the correct coordinate space (by judicious matrix multiplication). Note that the transformation matrix returned by GetTransform() is relative to the last PlaceWidget() invocation. (The PlaceWidget() sets the origin around which rotation and scaling occurs; the origin is the center point of the bounding box provided.)

virtual void vtkAffineRepresentation2D::SetBoxWidth ( int )

virtual

Specify the width of the various parts of the representation (in pixels).

		double	oy,
		double	oz
	)

void vtkAffineRepresentation2D::GetTransform ( vtkTransform * t )

overridevirtual

Retrieve a linear transform characterizing the affine transformation generated by this widget.

This method copies its internal transform into the transform provided. Note that the PlaceWidget() method initializes the internal matrix to identity. All subsequent widget operations (i.e., scale, translate, rotate, shear) are concatenated with the internal transform.
