status line number display

[Steve Nanchy]

Is there any way to make the status line under the tool icons (x/y/height/width/angle/et.al.) show THREE decimals (or more) instead of two?

Hi Nanchy,

sorry, it is hardcoded: In most cases, it's a simple call to IJ.d2s, which defaults to two decimals.

To change it, you would have to change line 711 in IJ.java and build your own version of ImageJ (which is not a big deal: just download the sources; in Linux or MacOS type 'ant' in the source directory).

Maybe an option to change the default decimals might be handy for others, too?
(Sometimes I also have images where the pixel size is much smaller than 1 in 'natural units').

Note that you can remove the mouse motion listener similar to what I have
done in the Hue Game:

https://github.com/fiji/fiji/blob/ffmpeg/plugins/Examples/The_Hue_Game.bsh

This is a Beanshell demonstrating how to override a given image's mouse
motion listener. All you would have to do is to implement the mouseMoved()
method and call showStatus() with an appropriate parameter.

You could also make it a new tool, it could even be done using ImageJ 1.x'
PlugInTool (you would not need Fiji's more sophisticated tool framework,
although that would help you prevent massive code duplication when
processing mouse events).

Something like

        import ij.IJ;
        import ij.ImagePlus;

        import ij.gui.GenericDialog;
        import ij.gui.ImageCanvas;

        import ij.plugin.tool.PlugInTool;

        import java.awt.event.MouseEvent;

        public class N_Digits extends PlugInTool {
                protected int digits = 3;

                public void mouseMoved(ImagePlus imp, MouseEvent e) {
                        ImageCanvas ic = imp.getCanvas();
                        int sx = e.getX();
                        int sy = e.getY();
                        int ox = ic.offScreenX(sx);
                        int oy = ic.offScreenY(sy);

                        String message;
                        if (ox < 0 || oy < 0 || ox >= imp.getWidth() || oy >= imp.getHeight())
                                return;
                        message = "x=" + ox + ", y=" + oy + " value=";
                        if (imp.getType() == ImagePlus.COLOR_RGB) {
                                int value = imp.getProcessor().getPixel(ox, oy);
                                message += "" + ((value >> 16) & 0xff) + "," + ((value >> 8) & 0xff) + "," + (value & 0xff);
                        }
                        else
                                message += IJ.d2s(imp.getProcessor().getf(ox, oy), digits);
                        IJ.showStatus(message);

                        // Tell ImageJ 1.x not to bother with the status
                        e.consume();
                }

                public void showOptionsDialog() {
                        GenericDialog gd = new GenericDialog("N Digits Options");
                        gd.addNumericField("Number_of_digits", digits, 0);
                        gd.showDialog();
                        if (!gd.wasCanceled())
                                digits = (int)gd.getNextNumber();
                }
        }

should get you started. Should you use Fiji, just start the Script Editor
using File>New>Script, select Java from the Language menu, paste above
Java code and call Run>Run.

Have fun playing,
Johannes
