◆ Extract() [2/3]

void Isis::Chip::Extract	(	int	samp,
		int	line,
		Chip &	chipped
	)

Extract a subchip centered at the designated coordinate.

This method extracts a subchip that is centered at the given sample and line coordinate. All appropriate variables in the given chipped parameter are set appropriately prior to return.

Parameters

samp	Center (tack) sample chip coordinate to extract subchip
line	Center (tack) line chip coordinate to extract subchip
chipped	Chip to load the subchip in and return to caller

References Lines(), Isis::Null, Samples(), SetValue(), TackLine(), and TackSample().

◆ Extract() [3/3]

void Isis::Chip::Extract	(	Chip &	chipped,
		Affine &	affine
	)

Extract a subchip of this chip using an Affine transform.

This method will translate the data in this chip using an Affine transform to the output chip as provided. Note that the Affine transformation is only applied within the confines of this chip. No file I/O is performed.

A proper Affine transform should not deviate too much from the identity as the mapping operation may result in a NULL filled chip. The operation of this affine is added to the existing affine so proper relationship to the input cube (and any affine operations applied at load time) is preserved. This implies that the resulting affine should yield nearly identical results when read directly from the cube.

Bilinear interpolation is applied to surrounding transformed pixels to provide each new output pixel.

The chipped parameter will be updated to fully reflect the state of this original chip. The state of the chipped parameter dictates the size and the tack sample and line coordinates. Upon return, the corresponding cube sample and line coordinate is updated to the tack sample and line chip coordinate.

As such, note that an identity affine transform will yield identical results to the Chip::Extract method specifying the tack sample and line as the location to extract.

The following example demonstrates how to linearly shift a chip one pixel right and one down.

Chip mychip(35,35);
Cube cube("mycube.cub");
mychip.TackCube(200.0,200.0);
mychip.Load(cube);
Affine shift;
shift.Translate(-1.0,-1.0);
Chip ochip(15,15);
mychip.Extract(ochip, shift);

Parameters

chipped	Input/output chip containing the transformed subchip
affine	Affine transform to apply to extract subchip

◆ Load() [3/3]

void Isis::Chip::Load	(	Cube &	cube,
		const Affine &	affine,
		const bool &	keepPoly = `true`,
		const int	band = `1`
	)

Load a chip using an Affine transform as provided by caller.

This method will load data from a cube using an established Affine transform as provided by the caller. It is up to the caller to set up the affine appropriately.

For example, the first thing this method will do is set the chip tack point to the transformed cube location by replacing the existing affine transform with the one passed in and then calling SetChipPosition providing the chip tack point as the argument. This establishes which cube pixel is located at the chip tack point.

The data will be loaded to sub-pixel accuracy using the interpolator indicated using SetReadInterpolator() method.

Parameters

cube	Cube to load the data from
affine	Affine transform to set for chip load/operations
keepPoly	Indicates whether clipping polygon should be kept or removed (default of true)
band	Band number to read data from (default of 1)
