Member Function Documentation

vtkWin32ImageMapper* vtkWin32ImageMapper::New (    )  [static]

Instantiate object with no start, end, or progress methods. Reimplemented from vtkImageMapper.

virtual const char* vtkWin32ImageMapper::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 vtkImageMapper.

int vtkWin32ImageMapper::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 vtkImageMapper.

virtual int vtkWin32ImageMapper::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 vtkImageMapper.

vtkWin32ImageMapper* vtkWin32ImageMapper::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 vtkImageMapper.

void vtkWin32ImageMapper::RenderOverlay (  vtkViewport *    viewport, vtkActor2D *    actor )  [inline, virtual]

Handle the render method. Reimplemented from vtkMapper2D. Definition at line 70 of file vtkWin32ImageMapper.h.

void vtkWin32ImageMapper::RenderData (  vtkViewport *    viewport, vtkImageData *    data, vtkActor2D *    actor )  [virtual]

Called by the Render function in vtkImageMapper. Actually draws the image to the screen. Reimplemented from vtkImageMapper.

unsigned long int vtkWin32ImageMapper::GetMTime (    )  [virtual]

Compute modified time including lookuptable Reimplemented from vtkImageMapper.

void vtkWin32ImageMapper::PrintSelf (  ostream &    os, vtkIndent    indent )  [virtual]

standard Printself routine Reimplemented from vtkImageMapper.

virtual void vtkWin32ImageMapper::SetLookupTable (  vtkLookupTable *    )  [virtual]

The ImageMappers convert ImageData into a greyscale image when a single scalar component is present. If a lookuptable is supplied, values are mapped through the lookuptable to generate a colour image. If the number of scalar components is greater then one, the lookuptable is ignored. If the lookuptable is NULL, a default greyscale image is generated. Users should ensure that the range of the lookuptable is {0,255} for full colour effects

virtual vtkLookupTable* vtkWin32ImageMapper::GetLookupTable (    )  [virtual]

HBITMAP vtkWin32ImageMapper::CreateBitmapObject (  HBITMAP    oldBitmap, BITMAPINFO &    dataHeader, HDC    windowDC, unsigned char *&    DataOut, vtkImageData *    data, int    width, int    height )  [static]

CreateBitmapObject and GenerateBitmapData are utility functions which allow one to hook into the display routines and provide the user with an easy way of converting an ImageData object into a windows bitmap object. They are also used internally by the mapper and should not be modified or used standalone alone without caution.

void vtkWin32ImageMapper::GenerateBitmapData (  vtkImageData *    data, void *    inptr, unsigned char *    DataOut, int    dim, int    DisplayExtent[6], float    cwindow, float    clevel, float    cshift, float    cscale, vtkLookupTable *    lut )  [static]

void vtkWin32ImageMapper::operator= (  const vtkWin32ImageMapper &    )  [inline, protected]
