To create an instance of class vtkRayCastImageDisplayHelper, simply invoke its constructor as follows
obj = vtkRayCastImageDisplayHelper
obj
is an instance of the vtkRayCastImageDisplayHelper class.
string = obj.GetClassName ()
int = obj.IsA (string name)
vtkRayCastImageDisplayHelper = obj.NewInstance ()
vtkRayCastImageDisplayHelper = obj.SafeDownCast (vtkObject o)
obj.RenderTexture (vtkVolume vol, vtkRenderer ren, int imageMemorySize[2], int imageViewportSize[2], int imageInUseSize[2], int imageOrigin[2], float requestedDepth, string image)
obj.RenderTexture (vtkVolume vol, vtkRenderer ren, int imageMemorySize[2], int imageViewportSize[2], int imageInUseSize[2], int imageOrigin[2], float requestedDepth, short image)
obj.RenderTexture (vtkVolume vol, vtkRenderer ren, vtkFixedPointRayCastImage image, float requestedDepth)
obj.SetPreMultipliedColors (int )
int = obj.GetPreMultipliedColorsMinValue ()
int = obj.GetPreMultipliedColorsMaxValue ()
int = obj.GetPreMultipliedColors ()
obj.PreMultipliedColorsOn ()
obj.PreMultipliedColorsOff ()
obj.SetPixelScale (float )
- Set / Get the pixel scale to be applied to the image before display.
Can be set to scale the incoming pixel values - for example the
fixed point mapper uses the unsigned short API but with 15 bit
values so needs a scale of 2.0.
