Detailed Description

High-quality image resizing filter.

vtkImageResize will magnify or shrink an image with interpolation and antialiasing. The resizing is done with a 5-lobe Lanczos-windowed sinc filter that is bandlimited to the output sampling frequency in order to avoid aliasing when the image size is reduced. This filter utilizes a O(n) algorithm to provide good effiency even though the filtering kernel is large. The sinc interpolator can be turned off if nearest-neighbor interpolation is required, or it can be replaced with a different vtkImageInterpolator object.

virtual void vtkImageResize::GetMagnificationFactors ( double  [3])
virtual

The desired magnification factor, meaning that the sample spacing will be reduced by this factor. This setting is only used if the ResizeMethod is set to MagnificationFactors.

virtual void vtkImageResize::SetBorder ( int  )
virtual

If Border is Off (the default), then the centers of each of the corner voxels will be considered to form the rectangular bounds of the image. This is the way that VTK normally computes image bounds. If Border is On, then the image bounds will be defined by the outer corners of the voxels. This setting impacts how the resizing is done. For example, if a MagnificationFactor of two is applied to a 256x256 image, the output image will be 512x512 if Border is On, or 511x511 if Border is Off.

virtual void vtkImageResize::BorderOn ( )

If Border is Off (the default), then the centers of each of the corner voxels will be considered to form the rectangular bounds of the image. This is the way that VTK normally computes image bounds. If Border is On, then the image bounds will be defined by the outer corners of the voxels. This setting impacts how the resizing is done. For example, if a MagnificationFactor of two is applied to a 256x256 image, the output image will be 512x512 if Border is On, or 511x511 if Border is Off.
