Detailed Description

interactive manipulation of the camera specialized for images

vtkInteractorStyleImage allows the user to interactively manipulate (rotate, pan, zoomm etc.) the camera. vtkInteractorStyleImage is specially designed to work with images that are being rendered with vtkImageActor. Several events are overloaded from its superclass vtkInteractorStyle, hence the mouse bindings are different. (The bindings keep the camera's view plane normal perpendicular to the x-y plane.) In summary the mouse events are as follows: + Left Mouse button triggers window level events + CTRL Left Mouse spins the camera around its view plane normal + SHIFT Left Mouse pans the camera + CTRL SHIFT Left Mouse dollys (a positional zoom) the camera + Middle mouse button pans the camera + Right mouse button dollys the camera. + SHIFT Right Mouse triggers pick events

Note that the renderer's actors are not moved; instead the camera is moved.

Member Function Documentation

static vtkInteractorStyleImage* vtkInteractorStyleImage::New ( ) [static]

This class must be supplied with a vtkRenderWindowInteractor wrapper or parent. This class should not normally be instantiated by application programmers.

Reimplemented from vtkInteractorStyleTrackballCamera.

Reimplemented in vtkInteractorStyleTreeMapHover.

virtual const char* vtkInteractorStyleImage::GetClassName ( ) [virtual]

Reimplemented from vtkInteractorStyleTrackballCamera.

Reimplemented in vtkInteractorStyleTreeMapHover.

static int vtkInteractorStyleImage::IsTypeOf ( const char * name ) [static]

Return 1 if this class type is the same type of (or a subclass of) the named class. Returns 0 otherwise. This method works in combination with vtkTypeMacro found in vtkSetGet.h.

Reimplemented from vtkInteractorStyleTrackballCamera.

Reimplemented in vtkInteractorStyleTreeMapHover.

virtual int vtkInteractorStyleImage::IsA ( const char * name ) [virtual]

Return 1 if this class is the same type of (or a subclass of) the named class. Returns 0 otherwise. This method works in combination with vtkTypeMacro found in vtkSetGet.h.

Reimplemented from vtkInteractorStyleTrackballCamera.

Reimplemented in vtkInteractorStyleTreeMapHover.

static vtkInteractorStyleImage* vtkInteractorStyleImage::SafeDownCast ( vtkObject * o ) [static]

Reimplemented from vtkInteractorStyleTrackballCamera.

Reimplemented in vtkInteractorStyleTreeMapHover.

void vtkInteractorStyleImage::PrintSelf	(	ostream &	os,
		vtkIndent	indent
	)			`[virtual]`

Methods invoked by print to print information about the object including superclasses. Typically not called by the user (use Print() instead) but used in the hierarchical print process to combine the output of several classes.

Reimplemented from vtkInteractorStyleTrackballCamera.

Reimplemented in vtkInteractorStyleTreeMapHover.
