Method Details

getDataset

public org.eclipse.january.dataset.IDataset getDataset()
                                                throws DeviceException

Compute Gaussian intensity distribution on 2-dimensional dataset. Intensity is centred on position given by xScannable and yScannable

Specified by:

getDataset in class DatasetNexusDetector

Returns:

A dataset object. .

Throws:

DeviceException

getPixelPosition

public org.apache.commons.math3.geometry.euclidean.twod.Vector2D getPixelPosition(double xpos,
 double ypos)

Compute pixel position on the image plane for given x and y 'real space' coordinates by :

Convert real (xpos, ypos) to fractional position between lower and upper position limits

Pixel position = Fractional position * image size (Image plane covers real positions from lowerPositionLimit (pixel=0,0) to upperPositionLimit (pixel=imageSize.x, imageSize.y))

Parameters:

xpos -

ypos -

Returns:

getIntensity

public double getIntensity(org.apache.commons.math3.geometry.euclidean.twod.Vector2D origin,
 double xpos,
 double ypos)

Compute a intensity value of Gaussian, for coordinate (xpos, ypos) with Gaussian centred at 'origin'

Parameters:

origin -

xpos -

ypos -

Returns:
