    • showElapsedTime

      public static final java.lang.String showElapsedTime​(java.lang.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 java.lang.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​(java.lang.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
