Detailed Description

widget for cropping an image

This widget displays a set of axis aligned lines that can be interactively manipulated to crop a volume. The region to be cropped away is displayed in a different highlight. Much like the vtkVolumeMapper, this widget supports 27 possible configurations of cropping planes. (See CroppingRegionFlags). If a volume mapper is set, the cropping planes are directly propagated to the volume mapper. The widget invokes a CroppingPlanesPositionChangedEvent when the position of any of the cropping planes is changed. The widget also invokes an InteractionEvent in response to user interaction.

Events:

vtkCommand::DisableEvent vtkCommand::EndInteractionEvent vtkCommand::InteractionEvent vtkCommand::StartInteractionEvent vtkCommand::EnableEvent

virtual void vtkImageCroppingRegionsWidget::PlaceWidget

(

double

bounds[6]

)

[virtual]

This method is used to initially place the widget. The placement of the widget depends on whether a Prop3D or input dataset is provided. If one of these two is provided, they will be used to obtain a bounding box, around which the widget is placed. Otherwise, you can manually specify a bounds with the PlaceWidget(bounds) method. Note: PlaceWidget(bounds) is required by all subclasses; the other methods are provided as convenience methods.

Implements vtk3DWidget.
