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 vtkPlot.

Reimplemented in vtkColorTransferFunctionItem, vtkLookupTableItem, vtkCompositeTransferFunctionItem, and vtkPiecewiseFunctionItem.

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 vtkPlot.

void vtkScalarsToColorsItem::GetBounds ( double  bounds[4])
overridevirtual

Bounds of the item, use the UserBounds if valid otherwise compute the bounds of the item (based on the transfer function range).

Reimplemented from vtkPlot.

Set custom bounds, except if bounds are invalid, bounds will be automatically computed based on the range of the control points Invalid bounds by default.

Set custom bounds, except if bounds are invalid, bounds will be automatically computed based on the range of the control points Invalid bounds by default.

bool vtkScalarsToColorsItem::Paint ( vtkContext2D painter)
overridevirtual

Paint the texture into a rectangle defined by the bounds.

If MaskAboveCurve is true and a shape has been provided by a subclass, it draws the texture into the shape

Reimplemented from vtkAbstractContextItem.

virtual vtkPen* vtkScalarsToColorsItem::GetPolyLinePen ( )
virtual

Get a pointer to the vtkPen object that controls the drawing of the edge of the shape if any.

PolyLinePen type is vtkPen::NO_PEN by default.

virtual void vtkScalarsToColorsItem::SetMaskAboveCurve ( bool  )
virtual

Don't fill in the part above the transfer function.

If true texture is not visible above the shape provided by subclasses, otherwise the whole rectangle defined by the bounds is filled with the transfer function. Note: only 2D transfer functions (RGB tf + alpha tf ) support the feature.

virtual bool vtkScalarsToColorsItem::GetMaskAboveCurve ( )
virtual

Don't fill in the part above the transfer function.

If true texture is not visible above the shape provided by subclasses, otherwise the whole rectangle defined by the bounds is filled with the transfer function. Note: only 2D transfer functions (RGB tf + alpha tf ) support the feature.

virtual void vtkScalarsToColorsItem::ComputeBounds ( double bounds)
protectedvirtual

Bounds of the item, by default (0, 1, 0, 1) but it depends on the range of the ScalarsToColors function.

Need to be reimplemented by subclasses if the range is != [0,1]

virtual void vtkScalarsToColorsItem::ComputeTexture ( )
protectedpure virtual

Need to be reimplemented by subclasses, ComputeTexture() is called at paint time if the texture is not up to date compared to vtkScalarsToColorsItem Return false if no texture is generated.

Implemented in vtkColorTransferFunctionItem, vtkLookupTableItem, vtkPiecewiseFunctionItem, and vtkCompositeTransferFunctionItem.

Called whenever the ScalarsToColors function(s) is modified.

It internally calls Modified(). Can be reimplemented by subclasses
