Detailed Description

2D image display

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.

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

Reimplemented from vtkMapper2D.

Reimplemented in vtkMesaImageMapper, and vtkOpenGLImageMapper.

static 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, and vtkOpenGLImageMapper.

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, and vtkOpenGLImageMapper.

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

Reimplemented from vtkMapper2D.

Reimplemented in vtkMesaImageMapper, and vtkOpenGLImageMapper.

static vtkImageMapper* vtkImageMapper::New  )  [static]
 

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

Reimplemented from vtkAlgorithm.

Reimplemented in vtkMesaImageMapper, and vtkOpenGLImageMapper.

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, and vtkOpenGLImageMapper.

unsigned long int vtkImageMapper::GetMTime  )  [virtual]
 

Override Modifiedtime as we have added a lookuptable

Reimplemented from vtkAbstractMapper.

virtual void vtkImageMapper::SetColorWindow double   )  [virtual]
 

Set/Get the window value for window/level

virtual double vtkImageMapper::GetColorWindow  )  [virtual]
 

Override Modifiedtime as we have added a lookuptable

virtual void vtkImageMapper::SetColorLevel double   )  [virtual]
 

Set/Get the level value for window/level

virtual double 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.

vtkActor2D
[pure virtual]
 

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

double vtkImageMapper::GetColorShift  ) 
 

Methods used internally for performing the Window/Level mapping.

double vtkImageMapper::GetColorScale  )

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 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

virtual int vtkImageMapper::FillInputPortInformation int  ,
vtkInformation
[protected, virtual]
 

Fill the input port information objects for this algorithm. This is invoked by the first call to GetInputPortInformation for each port so subclasses can specify what they can handle.

Reimplemented from vtkAlgorithm.
