Constructor & Destructor Documentation

iASlicer()

iASlicer::iASlicer	(	QWidget *	parent,
		const iASlicerMode	mode,
		bool	decorations = true,
		bool	magicLensAvailable = true,
		vtkAbstractTransform *	transform = nullptr,
		vtkPoints *	snakeSlicerPoints = nullptr
	)

Creates a new slicer widget.

Parameters

parent	the parent widget; can be nullptr for no current parent.
mode	determines which axis-aligned slice-plane is used for slicing.
decorations	whether to show the scalar bar widget, the measure bar, the logo and the tooltip.
magicLensAvailable	whether a magic lens should be available.
transform	the basic transform the reslicers inside the channels of this slicer (should probably be removed here).
snakeSlicerPoints	the array of points in the snake slicer (leave at default nullptr if you don't require snake slicer).
