Method Detail

create

public static ij.process.LUT create(byte[] r,
                                    byte[] g,
                                    byte[] b)

Create a new lookup-table from three RGB arrays of length 256.

Parameters:

r - Red component values.

g - Green component values.

b - Blue component values.

Returns:

A new instance of type LUT.

fire

public static ij.process.LUT fire()

ImageJ's 'fire' LUT, as originally defined in class LutLoader.

Returns:

A new instance of type LUT.

grays

public static ij.process.LUT grays()

ImageJ's 'grays' LUT, as originally defined in class LutLoader.

Returns:

A new instance of type LUT.

ice

public static ij.process.LUT ice()

ImageJ's 'ice' LUT, as originally defined in class LutLoader.

Returns:

A new instance of type LUT.

spectrum

public static ij.process.LUT spectrum()

ImageJ's 'spectrum' LUT, as originally defined in class LutLoader.

Returns:

A new instance of type LUT.

rgb332

public static ij.process.LUT rgb332()

ImageJ's 'rgb332' LUT, as originally defined in class LutLoader.

Returns:

A new instance of type LUT.

redgreen

public static ij.process.LUT redgreen()

ImageJ's 'redgreen' LUT, as originally defined in class LutLoader.

Returns:

A new instance of type LUT.

listCurrentLut

public static void listCurrentLut(ij.process.ImageProcessor ip)

Lists the contents of the lookup-table currently associated with the specified image.

Parameters:

ip - The image.

brightLut

public static void brightLut(ij.process.ImageProcessor ip,
                             int minGray)

Modifies the lookup table to display a bright image with gray values in the range minGray ... 255. Does nothing if ip is of type ColorProcessor.

Parameters:

ip - The target image.

minGray - Minimum gray value.
