vtkImageViewer - Display a 2d image.

Description:

vtkImageViewer is a convinience class for displaying a 2d image. It packages up the functionality found in vtkImageWindow, vtkImager, vtkActor2D and vtkImageMapper into a single easy to use class. Behind the scenes these four classes are actually used to to provide the required functionality. vtkImageViewer is simply a wrapper around them.

Detailed Method Descriptions:

Get name of rendering window

char *GetWindowName ()

Render the resulting image.

void Render ()

Set/Get the input to the viewer.

	void SetInput (vtkImageCache *)
	vtkImageCache *GetInput ()
	void SetInput (vtkStructuredPoints *)

What is the possible Min/ Max z slices available.

	int GetWholeZMin ()
	int GetWholeZMax ()

Set/Get the current Z Slice to display

	int GetZSlice ()
	void SetZSlice (int )

Sets window/level for mapping pixels to colors.

	float GetColorWindow ()
	float GetColorLevel ()
	void SetColorWindow (float )
	void SetColorLevel (float )

These are here for using a tk window.

	void SetDisplayId (void *)
	void SetWindowId (void *)
	void SetParentId (void *)

By default this is a color viewer. GrayScaleHintOn will improve the appearance of gray scale images on some systems.

	int GetGrayScaleHint ()
	void SetGrayScaleHint (int )
	void GrayScaleHintOn ()
	void GrayScaleHintOff ()

Set/Get the position in screen coordinates of the rendering window.

	int *GetPosition ()
	void SetPosition (int ,int )
	void SetPosition (int )

Set/Get the size of the window in screen coordinates.

	int *GetSize ()
	void SetSize (int ,int )
	void SetSize (int )

Get the internal Window Imager and Mapper

	vtkImageWindow *GetImageWindow ()
	vtkImageMapper *GetImageMapper ()
	vtkImager *GetImager ()
	vtkActor2D *GetActor2D ()
