Detailed Description

topologically and geometrically regular array of data

vtkImageData is a data object that is a concrete implementation of vtkCartesianGrid. vtkImageData represents a geometric structure that is a topological and geometrical regular array of points. Examples include volumes (voxel data) and pixmaps. This representation supports images up to three dimensions. The image may also be oriented (see the DirectionMatrices and related transformation methods). Note however, that not all filters support oriented images. It also supports blanking.

◆ GetContinuousIncrements() [1/2]

virtual void vtkImageData::GetContinuousIncrements	(	int	extent[6],
		vtkIdType &	incX,
		vtkIdType &	incY,
		vtkIdType &	incZ
	)

virtual

Different ways to get the increments for moving around the data.

incX is always returned with 0. incY is returned with the increment needed to move from the end of one X scanline of data to the start of the next line. incZ is filled in with the increment needed to move from the end of one image to the start of the next. The proper way to use these values is to for a loop over Z, Y, X, C, incrementing the pointer by 1 after each component. When the end of the component is reached, the pointer is set to the beginning of the next pixel, thus incX is properly set to 0. The first form of GetContinuousIncrements uses the active scalar field while the second form allows the scalar array to be passed in.
