Method Detail

setup

public int setup(java.lang.String arg,
                 ImagePlus imp)

Description copied from interface: PlugInFilter

This method is called once when the filter is loaded. 'arg', which may be blank, is the argument specified for this plugin in IJ_Props.txt. 'imp' is the currently active image. This method should return a flag word that specifies the filters capabilities.

Specified by:

setup in interface PlugInFilter

run

public void run(ImageProcessor ip)

Description copied from interface: PlugInFilter

Filters use this method to process the image. If the SUPPORTS_STACKS flag was set, it is called for each slice in a stack. ImageJ will lock the image before calling this method and unlock it when the filter is finished.

Specified by:

run in interface PlugInFilter

convolve

public boolean convolve(ImageProcessor ip,
                        float[] kernel,
                        int kw,
                        int kh)

setNormalize

public void setNormalize(boolean normalizeKernel)

convolveRGB

public void convolveRGB(ImageProcessor ip,
                        float[] kernel,
                        int kw,
                        int kh)

convolveFloat

public boolean convolveFloat(ImageProcessor ip,
                             float[] kernel,
                             int kw,
                             int kh)

Convolves the image ip with a kernel of width kw and height kh. Returns false if the user cancels the operation by pressing 'Esc'.

actionPerformed

public void actionPerformed(java.awt.event.ActionEvent e)
