Detailed Description

draw an image in a rendered 3D scene

vtkImageActor is used to render an image in a 3D scene. The image is placed at the origin of the image, and its size is controlled by the image dimensions and image spacing. The orientation of the image is orthogonal to one of the x-y-z axes depending on which plane the image is defined in. This class has been mostly superseded by the vtkImageSlice class, which provides more functionality than vtkImageActor.

void vtkImageActor::SetDisplayExtent	(	int	minX,
		int	maxX,
		int	minY,

◆ GetBounds() [1/2]

double * vtkImageActor::GetBounds ( )

overridevirtual

Get the bounds of this image actor.

Either copy the bounds into a user provided array or return a pointer to an array. In either case the bounds is expressed as a 6-vector (xmin,xmax, ymin,ymax, zmin,zmax).

Implements vtkProp3D.

◆ GetBounds() [2/2]

Get the bounds of this image actor.

Either copy the bounds into a user provided array or return a pointer to an array. In either case the bounds is expressed as a 6-vector (xmin,xmax, ymin,ymax, zmin,zmax).

Again the number of slices is in reference to the display z axis, which is not necessarily the z axis on disk. (due to reformatting etc)
