Labelling of objects - font size

[mdhiggins]

Hello,

I want to label objects. I use Analyse/Analyse particles and select show: outlines.
I see an image with the outlines labelled, but the numbers are tiny.
I can't find a control to make the labels bigger.

Thanks  Michael

Hi Michael,

if you write a program or script in Java or Javascript, you can use the
public method setFontSize of the ParticleAnaliyzer.
To get this working, you have to create a new ParticleAnalyzer with its
constructor (specify PartileAnalyzer.SHOW_OUTLINES as options), then call
its setFontSize and analyze methods. Unfortunately, this not as easy as a
simple 'run("Analyze Particles..", options) command.

Dear Michael,

You could use 'Bare Outlines' (alternatively, create an empty image of the same size as your original) and select 'Add to Manager' in Analyse Particles. In the ROI Manager you can use 'Show All' and 'Labels'. Under 'More>> Labels' you can change the way the numbers are displayed. The color of the selection can be changed in the ROI Manager under 'Properties'.

Best wishes

Kees

Thanks for the advice. I now see what I want, but I can't work out how to print it, except by screen capture - which seems like cheating.

The morphology collection at:
http://www.mecourse.com/landinig/software/software.html
includes a macro: NumberParticles8.txt that numbers regions and you can change
the font size easily in the code.
Cheers

Use the Show: Overlay Outlines option and you will be able to change the font size in the Image>Overlay>Labels dialog. Here is a macro example:

  run("Blobs (25K)");
  setAutoThreshold("Default");
  run("Analyze Particles...", "size=450 show=[Overlay Outlines]");
  resetThreshold();
  run("Labels...", "color=white font=14 show draw");
  run("Set... ", "zoom=200");
