Measure + label with result macro

Hello!

I’m looking for a macro with which I can

a) measure an angle, or distance (line tool) or area (oval or polygon selection tool)
b) display the result of that measurement (i.e. angle, or area or length)
c) adds this selection to the overlay in yellow.

So far especially b proved to be difficult most macros I found just lable with A,B,C or numbers not with the result.

So I found this one but it does not work..

macro "Measure and Label [m]" {
run("Measure");
label = "" + getResult("Length", nResults-1);
if (label=="NaN" || label=="0")
label = "" + getResult("Area", nResults-1);
label = "" + getResult("Angle", nResults-1);
Roi.setName(label);
Overlay.addSelection;
}

Maybe someone can help to debug?

Thanks, Till

Re: Measure + label with result macro

Hi Till,

below is a modification of your macro, based on my understanding of your specifications. It can be expanded if different selections/measures want to be included.
Everything is handled through overlays, including the labeling.

ITH,
Giovanni

macro "measure and label" {

if (nImages==0) {
exit("No images are open");
}

imageTitle = getTitle();
type = selectionType();

// in case the user forgot to make a selection
if (type == -1) {
waitForUser("Draw a ROI on the image " + imageTitle + " and press OK");
}

type = selectionType();

// check selection type and measure to perform
if (type==1 || type==2) {
field = "Area";
} else if (type==5) {
field = "Length";
} else if (type==8) {
field = "Angle";
} else {
exit("I don't know what to do");
}

run("Measure");
label = "" + getResult(field, nResults-1);

// get top left coordinates of bounding box
getSelectionBounds(x, y, width, height);

// add selection and measure as overlays
Overlay.addSelection;
Overlay.drawString(label, x, y)

}
