Constructor Detail

VectorProcessor

public VectorProcessor(int width,
               int height,
               int numberOfValues)

VectorProcessor

public VectorProcessor(ij.process.ColorProcessor cp)

VectorProcessor

public VectorProcessor(ij.ImagePlus imp)

VectorProcessor

public VectorProcessor(ij.ImageStack stack)

Parameters:

stack - a stack of FloatProcessors.

Method Detail

getWidth

public int getWidth()

Returns:

width of the image.

getHeight

public int getHeight()

Returns:

height of the image.

getNumberOfValues

public int getNumberOfValues()

Returns:

number of values at each pixel in the image.

getPixels

public float[][] getPixels()

Gives direct access to pixel values in the image first index is the pixel number (between 0 and width*height-1), the second index references within each pixel value.

Returns:

reference to the array containing pixel values in the image.

getRoi

public java.awt.Rectangle getRoi()

Returns:

region of interest within the image.

setRoi

public void setRoi(java.awt.Rectangle roi)

Parameters:

roi - new ROI.

getRoi()

getProgressBar

public ij.gui.ProgressBar getProgressBar()

setProgressBar

public void setProgressBar(ij.gui.ProgressBar progressBar)

pixelIterator

public VectorProcessor.PixelIterator pixelIterator()

Returns:

pixel value iterator.

iterator

public VectorProcessor.Iterator iterator()

Returns:

pixel value iterator.

toFloatProcessors

public ij.process.FloatProcessor[] toFloatProcessors()

Convert VectorProcessor to an array of FloatProcessor's.

Returns:

this VectorProcessor represented as an array of FloatProcessor's

toFloatStack()

toFloatStack

public ij.ImagePlus toFloatStack(java.lang.String[] labels)

Convert VectorProcessor to ImagePlus with FloatProcessor stack.

Parameters:

labels - labels to be assigned to slice in the stack. Number of labels must match number of pixel values (slices in the output stack). This argument cannot be null.

Returns:

ImagePlus representation of this object.
