Detailed Description

Buffer for containing a two dimensional section of an image.

This class is a Buffer. The shape of the buffer is two dimensional in the line and sample directions only. The band dimension is always one. This class provides a random access window into a cube. The position can be set to any line, sample and band, including outside the image.

If you would like to see Portal being used in implementation, see the ProcessRubberSheet class

Constructor & Destructor Documentation

◆ Portal()

Isis::Portal::Portal	(	const int	bufSamps,
		const int	bufLines,
		const Isis::PixelType	type,
		const double	hotSamp = `-0.5`,
		const double	hotLine = `-0.5`
	)

inline

Constructs a Portal object.

The hotspot defaults of (-0.5,-0.5) cause the nearest neighbor to the requested pixel to be returned in the top left corner of the portal buffer

Parameters

bufSamps	The number of samples in the portal.
bufLines	The number of lines in the portal.
type	Type of pixel in raw buffer
hotSamp	The point of interest within the buffer in the sample direction. When a buffer is being setup, the hotSamp will be subtracted from the point of interest to give a buffer of the requested size around the hot spot. This number is zero based. Defaults to 0.5
hotLine	The point of interest within the buffer in the line direction. When a buffer is being setup, the hotLine will be subtracted from the point of interest to give a buffer of the requested size around the hot spot. This number is zero based. Defaults to 0.5
