Constructor Detail

Patch

public Patch(ij.process.ImageProcessor image,
     int x,
     int y,
     int width,
     int height)

This makes a patch based on the given dimensions and view parameters.

Method Detail

setCorner

public void setCorner(int x,
             int y)

This moves the patch to have the upper left corner at (x,y) in image coordinates.

Overrides:

setCorner in class View

getWidth

public int getWidth()

getHeight

public int getHeight()

getSample

public int[] getSample(int x,
              int y,
              int[] out)

Bounds checks the input to make sure it is part of the patch and then gets the sample from the view.

Overrides:

getSample in class View

putSample

public void putSample(int x,
             int y,
             int[] values)

Bounds checks the input to make sure it is part of the patch and then puts the sample into the view.

Overrides:

putSample in class View

toString

public java.lang.String toString()

returns a string with the corner, width, and height listed

Overrides:

toString in class java.lang.Object

rightOnePixel

public boolean rightOnePixel()

This moves the patch one pixel to the right if able. If the move fails (because it puts part of the patch out of bounds) then this returns false.

nextPixelRow

public boolean nextPixelRow()

This moves the patch one pixel down and all the way to the left. If the move fails (because it puts part of the patch out of bounds) then this returns false.

nextRow

public boolean nextRow(int overlap)

This moves the patch to the left side of the image and down by height-overlap. If the move fails, this returns false.

nextColumn

public boolean nextColumn(int overlap)

This moves the patch to the right in this row of patches if able. The amount moved will be width-overlap. This returns false on failure.

getXOffset

public int getXOffset()

getYOffset

public int getYOffset()
