Detailed Description

pqTransferFunction2DWidget provides a widget that can edit control boxes in a 2D histogram to represent a 2D transfer function.

It is used by the pqColorOpacityEditorWidget, for example, to show 2D transfer function editor for color and opacity for a PVLookupTable proxy.

)

const

Set/Get vtkImageData used to initialize the 2D histogram.

setHistogram()

virtual void pqTransferFunction2DWidget::setHistogram ( vtkImageData *  )

virtual

Set/Get vtkImageData used to initialize the 2D histogram.

initialize()

void pqTransferFunction2DWidget::initialize

(

vtkPVTransferFunction2D *

tf2d

)

chart()

vtkChart* pqTransferFunction2DWidget::chart

(

)

const

Get access to the internal chart.

transferFunction()

vtkPVTransferFunction2D* pqTransferFunction2DWidget::transferFunction

(

)

const
