Method Summary

Modifier and Type	Method and Description
static String[]	getOpenImageNames() Return an array of String containing the name of all the currently open images.
static ij.text.TextWindow[]	getTableWindows() Iterates on the list of TextWindows, and keeps only the ones containing a non-null ResultsTable
static int[]	parseLabelList(String string) Extracts a list of integer labels from a string representation.
static void	printImage(ij.process.ImageProcessor image) Deprecated. use ImageUtils.print(ImageProcessor) instead
static String	showElapsedTime(String opName, double timeInMillis, ij.ImagePlus refImage) Display elapsed time, converted into seconds, and computes number of processed elements per second.

Method Detail

showElapsedTime

public static final String showElapsedTime(String opName,
                                           double timeInMillis,
                                           ij.ImagePlus refImage)

Display elapsed time, converted into seconds, and computes number of processed elements per second. Also returns the created message.

Example of use:

 // initialize processing 
 ImageStack image = IJ.getImage().getStack();
 Strel3D strel = CubeStrel.fromDiameter(5);
 
 // initialize timing 
 long t0 = System.currentTimeMillis();
 
 // start processing 
 ImageStack res = Morphology.dilation(image, strel);
 ImagePlus resPlus = new ImagePlus("Dilation Result", res);
 resPlus.show();
 
 // Display elapsed time
 long t1 = System.currentTimeMillis();
 IJUtils.showElapsedTime("dilation", t1 - t0, resPlus);
 

Parameters:

opName - the name of the operation (algorithm, plugin...)

timeInMillis - the elapsed time, in milliseconds

refImage - the image on which process was applied

Returns:

the String corresponding to the message displayed in status bar

getOpenImageNames

public static final String[] getOpenImageNames()

Return an array of String containing the name of all the currently open images. If no image is open, returns an array with zero element.

Returns:

an array of string containing the name of open images.

getTableWindows

public static final ij.text.TextWindow[] getTableWindows()

Iterates on the list of TextWindows, and keeps only the ones containing a non-null ResultsTable

Returns:

an array containing the list of open TextWindows

parseLabelList

public static final int[] parseLabelList(String string)

Extracts a list of integer labels from a string representation.

Parameters:

string - the String containing labels, separated by commas or spaces.

Returns:

the list of integer labels identified within the string

printImage

@Deprecated
public static final void printImage(ij.process.ImageProcessor image)

Deprecated. use ImageUtils.print(ImageProcessor) instead

Prints the content of the given ImageProcessor on the console. This can be used for debugging (small) images.

Parameters:

image - the image to display on the console
