public class View
extends java.lang.Object

This class is provides a view of an image. The view is a small part of the larger image. This provides a way to pass around parts of an image without actually copying the pixels. This does not ensure that the whole view is inside the image, so be careful.

Constructor Detail

View

public View(ij.process.ImageProcessor image,
    int x,
    int y)

This creates a new view of the given image.

Parameters:

image - This is the image to view.

x - This is the x coord of the upper left corner of the view in image's pixel coordinates.

y - This is the x coord of the upper left corner of the view in image's pixel coordinates.

Method Detail

setCorner

public void setCorner(int x,
             int y)

This moves the view to the specified position.

getCornerX

public int getCornerX()

returns the image x coordinate of the upper left corner of the view

getCornerY

public int getCornerY()

returns the image y coordinate of the upper left corner of the view

isAtLeftEdge

public boolean isAtLeftEdge()

returns true iff getCornerX() == 0

isAtTopEdge

public boolean isAtTopEdge()

returns true iff getCornerY() == 0

getSample

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

This fetches the RGB values from the given view coordinates.

putSample

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

This sets the RGB sample at the given view coordinates.
