Methods in net.grelf.grip with parameters of type PointFloat

Modifier and Type	Method and Description
void	StarMeasProcessor.addPoint(PointFloat pt)
static SkyPoint	Astrometry.measure(Image im, java.util.List<Star> refStars, java.util.List<PointFloat> refPoints, SkyPoint approxPlateCentre, PointFloat targetPoint) The image is assumed NOT to have been through an inverse gnomonic projection.
protected void	CometProcessor.process(PointFloat cometCentre, Image image) Called when each CometFrame closes - not for use otherwise.
void	CometFrame.setCometCentre(PointFloat pt)
static void	Warp.warp(Image imageOld, PointFloat[] oldPts, Image imageNew, PointFloat[] newPts) Warp imOld into separate image imNew, using second order polynomials.

Method parameters in net.grelf.grip with type arguments of type PointFloat

Modifier and Type	Method and Description
boolean	Accumulator.brightestShiftAccumulate(Image image, int imNo, int middleImNo, java.util.List<PointFloat> centres) For image imNo of a sequence, add the pixel values into the accumulator but first shift the image so that brightest objects in this image and the middle image of the sequence are superimposed. 9.11.26: changed last parameter from BlobMeas [][] lookup.
boolean	Accumulator32.brightestShiftAccumulate(Image image, int imNo, int middleImNo, java.util.List<PointFloat> centres) For image imNo of a sequence, add the pixel values into the accumulator but first shift the image so that brightest objects in this image and the middle image of the sequence are superimposed. NB: Does NOT set this.extremes, so must call getOverallRange () at end of sequence. 9.11.26: changed last parameter from BlobMeas [][] lookup.
boolean	Accumulator64.brightestShiftAccumulate(Image image, int imNo, int middleImNo, java.util.List<PointFloat> centres) For image imNo of a sequence, add the pixel values into the accumulator but first shift the image so that brightest objects in this image and the middle image of the sequence are superimposed. 9.11.26: changed last parameter from BlobMeas [][] lookup.
static SkyPoint	Astrometry.measure(Image im, java.util.List<Star> refStars, java.util.List<PointFloat> refPoints, SkyPoint approxPlateCentre, PointFloat targetPoint) The image is assumed NOT to have been through an inverse gnomonic projection.
