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]
 

Return the class name as a string. This method is defined in all subclasses of vtkObject with the vtkTypeMacro found in vtkSetGet.h.

Reimplemented from vtkMapper2D.

Reimplemented in vtkMesaImageMapper.

float vtkImageMapper::GetColorShift  
 

Methods used internally for performing the Window/Level mapping.

unsigned long int vtkImageMapper::GetMTime   [virtual]
 

Override Modifiedtime as we have added a lookuptable

Reimplemented from vtkObject.

Reimplemented in 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 vtkTypeMacro found in vtkSetGet.h.

Reimplemented from vtkMapper2D.

Reimplemented in vtkMesaImageMapper.

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 vtkTypeMacro found in vtkSetGet.h.

Reimplemented from vtkMapper2D.

Reimplemented in vtkMesaImageMapper.

vtkImageMapper* vtkImageMapper::New   [static]
 

Instantiate object with no start, end, or progress methods.

Reimplemented from vtkMapper2D.

Reimplemented in vtkMesaImageMapper.

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 vtkWin32ImageMapper.

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.

void vtkImageMapper::RenderStart vtkViewport   viewport,
vtkActor2D   actor
 

Draw the image to the screen.

vtkImageMapper* vtkImageMapper::SafeDownCast vtkObject   o [static]
 

Will cast the supplied object to vtkObject* is this is a safe operation (i.e., a safe downcast); otherwise NULL is returned. This method is defined in all subclasses of vtkObject with the vtkTypeMacro found in vtkSetGet.h.

Reimplemented from vtkMapper2D.

Reimplemented in vtkMesaImageMapper.

virtual void vtkImageMapper::SetColorLevel float    [virtual]
 

Set/Get the level value for window/level

virtual void vtkImageMapper::SetColorWindow float    [virtual]
 

Set/Get the window value for window/level

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::SetInput vtkImageData   [virtual]
 

Set/Get the input for the image mapper.

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 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 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)
