Revision:
1.31

vtkImageMapper provides 2D image display support for vtk. It is a Mapper2D subclass that can be associated with an Actor2D and placed within a RenderWindow or ImageWindow.

Member Function Documentation

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

Reimplemented from vtkMapper2D.

Reimplemented in vtkMesaImageMapper, vtkOpenGLImageMapper, and vtkWin32ImageMapper.

int vtkImageMapper::IsTypeOf (  const char *    type )  [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 vtkTypeRevisionMacro found in vtkSetGet.h.

Reimplemented from vtkMapper2D.

Reimplemented in vtkMesaImageMapper, vtkOpenGLImageMapper, and vtkWin32ImageMapper.

virtual int vtkImageMapper::IsA (  const char *    type )  [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 vtkTypeRevisionMacro found in vtkSetGet.h.

Reimplemented from vtkMapper2D.

Reimplemented in vtkMesaImageMapper, vtkOpenGLImageMapper, and vtkWin32ImageMapper.

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

Reimplemented from vtkMapper2D.

Reimplemented in vtkMesaImageMapper, vtkOpenGLImageMapper, and vtkWin32ImageMapper.

vtkImageMapper* vtkImageMapper::New (    )  [static]
 

Create an object with Debug turned off, modified time initialized to zero, and reference counting on.

Reimplemented from vtkObject.

Reimplemented in vtkMesaImageMapper, vtkOpenGLImageMapper, and vtkWin32ImageMapper.

void vtkImageMapper::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 vtkMapper2D.

Reimplemented in vtkMesaImageMapper, vtkOpenGLImageMapper, and vtkWin32ImageMapper.

unsigned long int vtkImageMapper::GetMTime (    )  [virtual]
 

Override Modifiedtime as we have added a lookuptable

Reimplemented from vtkAbstractMapper.

Reimplemented in vtkWin32ImageMapper.

virtual void vtkImageMapper::SetColorWindow (  float    )  [virtual]
 

Set/Get the window value for window/level

virtual float vtkImageMapper::GetColorWindow (    )  [virtual]
 

Set/Get the window value for window/level

virtual void vtkImageMapper::SetColorLevel (  float    )  [virtual]
 

Set/Get the level value for window/level

virtual float vtkImageMapper::GetColorLevel (    )  [virtual]
 

Set/Get the level value for window/level

virtual void vtkImageMapper::SetZSlice (  int    )  [virtual]
 

Set/Get the current slice number. The axis Z in ZSlice does not necessarily have any relation to the z axis of the data on disk. It is simply the axis orthogonal to the x,y, display plane. GetWholeZMax and Min are convenience methods for obtaining the number of slices that can be displayed. Again the number of slices is in reference to the display z axis, which is not necessarily the z axis on disk. (due to reformatting etc)

virtual int vtkImageMapper::GetZSlice (    )  [virtual]
 

Set/Get the current slice number. The axis Z in ZSlice does not necessarily have any relation to the z axis of the data on disk. It is simply the axis orthogonal to the x,y, display plane. GetWholeZMax and Min are convenience methods for obtaining the number of slices that can be displayed. Again the number of slices is in reference to the display z axis, which is not necessarily the z axis on disk. (due to reformatting etc)

int vtkImageMapper::GetWholeZMin (    ) 
 

Set/Get the current slice number. The axis Z in ZSlice does not necessarily have any relation to the z axis of the data on disk. It is simply the axis orthogonal to the x,y, display plane. GetWholeZMax and Min are convenience methods for obtaining the number of slices that can be displayed. Again the number of slices is in reference to the display z axis, which is not necessarily the z axis on disk. (due to reformatting etc)

int vtkImageMapper::GetWholeZMax (    ) 
 

Set/Get the current slice number. The axis Z in ZSlice does not necessarily have any relation to the z axis of the data on disk. It is simply the axis orthogonal to the x,y, display plane. GetWholeZMax and Min are convenience methods for obtaining the number of slices that can be displayed.

void vtkImageMapper::RenderStart (  vtkViewport *    viewport,
vtkActor2D *    actor
) 
 

Draw the image to the screen.

Referenced by vtkMesaImageMapper::RenderOpaqueGeometry(), vtkWin32ImageMapper::RenderOverlay(), and vtkOpenGLImageMapper::RenderOverlay().

virtual void vtkImageMapper::RenderData (  vtkViewport *   ,
vtkImageData *   ,
vtkActor2D *   
)  [pure virtual]
 

Function called by Render to actually draw the image to to the screen

Implemented in vtkMesaImageMapper, vtkOpenGLImageMapper, and vtkWin32ImageMapper.

float vtkImageMapper::GetColorShift (    ) 
 

Methods used internally for performing the Window/Level mapping.

float vtkImageMapper::GetColorScale (    ) 
 

Methods used internally for performing the Window/Level mapping.

virtual void vtkImageMapper::SetInput (  vtkImageData *    input )  [virtual]
 

Set the Input of a filter.

vtkImageData* vtkImageMapper::GetInput (    ) 
 

Set the Input of a filter.

virtual void vtkImageMapper::SetRenderToRectangle (  int    )  [virtual]
 

If RenderToRectangle is set (by default not), then the imagemapper will render the image into the rectangle supplied by the Actor2D's PositionCoordinate and Position2Coordinate

virtual int vtkImageMapper::GetRenderToRectangle (    )  [virtual]
 

If RenderToRectangle is set (by default not), then the imagemapper will render the image into the rectangle supplied by the Actor2D's PositionCoordinate and Position2Coordinate

virtual void vtkImageMapper::RenderToRectangleOn (    )  [virtual]
 

If RenderToRectangle is set (by default not), then the imagemapper will render the image into the rectangle supplied by the Actor2D's PositionCoordinate and Position2Coordinate

virtual void vtkImageMapper::RenderToRectangleOff (    )  [virtual]
 

If RenderToRectangle is set (by default not), then the imagemapper will render the image into the rectangle supplied by the Actor2D's PositionCoordinate and Position2Coordinate

virtual void vtkImageMapper::SetUseCustomExtents (  int    )  [virtual]
 

Usually, the entire image is displayed, if UseCustomExtents is set (by default not), then the region supplied in the CustomDisplayExtents is used in preference. Note that the Custom extents are x,y only and the zslice is still applied

virtual int vtkImageMapper::GetUseCustomExtents (    )  [virtual]
 

Usually, the entire image is displayed, if UseCustomExtents is set (by default not), then the region supplied in the CustomDisplayExtents is used in preference. Note that the Custom extents are x,y only and the zslice is still applied

virtual void vtkImageMapper::UseCustomExtentsOn (    )  [virtual]
 

Usually, the entire image is displayed, if UseCustomExtents is set (by default not), then the region supplied in the CustomDisplayExtents is used in preference. Note that the Custom extents are x,y only and the zslice is still applied

virtual void vtkImageMapper::UseCustomExtentsOff (    )  [virtual]
 

Usually, the entire image is displayed, if UseCustomExtents is set (by default not), then the region supplied in the CustomDisplayExtents is used in preference. Note that the Custom extents are x,y only and the zslice is still applied

virtual void vtkImageMapper::SetCustomDisplayExtents (  int    data[] )  [virtual]
 

The image extents which should be displayed with UseCustomExtents Note that the Custom extents are x,y only and the zslice is still applied

virtual int* vtkImageMapper::GetCustomDisplayExtents (    )  [virtual]
 

The image extents which should be displayed with UseCustomExtents Note that the Custom extents are x,y only and the zslice is still applied

virtual void vtkImageMapper::GetCustomDisplayExtents (  int    data[4] )  [virtual]
 

The image extents which should be displayed with UseCustomExtents Note that the Custom extents are x,y only and the zslice is still applied
