Field Detail

PREWITT_HORIZONTAL

public static final javax.media.jai.KernelJAI PREWITT_HORIZONTAL

Horizontal gradient mask according Prewitt (also know as smoothed).

PREWITT_VERTICAL

public static final javax.media.jai.KernelJAI PREWITT_VERTICAL

Vertical gradient mask according Prewitt (also know as smoothed).

ISOTROPIC_HORIZONTAL

public static final javax.media.jai.KernelJAI ISOTROPIC_HORIZONTAL

Horizontal gradient mask (isotropic).

ISOTROPIC_VERTICAL

public static final javax.media.jai.KernelJAI ISOTROPIC_VERTICAL

Vertical gradient mask (isotropic).

SOBEL_HORIZONTAL

public static final javax.media.jai.KernelJAI SOBEL_HORIZONTAL

Horizontal gradient mask according Sobel.

SOBEL_VERTICAL

public static final javax.media.jai.KernelJAI SOBEL_VERTICAL

Vertical gradient mask according Sobel.

KIRSCH_HORIZONTAL

public static final javax.media.jai.KernelJAI KIRSCH_HORIZONTAL

Horizontal gradient mask according Kirsch.

KIRSCH_VERTICAL

public static final javax.media.jai.KernelJAI KIRSCH_VERTICAL

Vertical gradient mask according Kirsch.

To Do:

Why positives numbers are on the first row? This is the opposite of other vertical gradient masks. Need to verify in J.J. Simpson (1990).

Constructor Detail

GradientKernelEditor

public GradientKernelEditor()

Constructs a new editor for gradient kernels.

Method Detail

addDefaultKernels

public void addDefaultKernels()

Adds a set of predefined kernels. This convenience method invokes KernelEditor.addDefaultKernels() on both horizontal and vertical kernel editors. The default implementation for those editors will add a set of Sobel kernels.

getHorizontalEditor

public KernelEditor getHorizontalEditor()

Returns the horizontal kernel editor.

getVerticalEditor

public KernelEditor getVerticalEditor()

Returns the vertical kernel editor.

showDialog

public boolean showDialog(java.awt.Component owner,
                          java.lang.String title)

Shows a dialog box requesting input from the user. If is contained into a JDesktopPane, the dialog box will appears as an internal frame. This method can be invoked from any thread (may or may not be the Swing thread).

Parameters:

owner - The parent component for the dialog box, or if there is no parent.

title - The dialog box title.

Returns:

if user pressed the "Ok" button, or otherwise (e.g. pressing "Cancel" or closing the dialog box from the title bar).

main

public static void main(java.lang.String[] args)

Show the dialog box. This method is provided only as an easy way to test the dialog appearance from the command line.
