Controlling font aliasing for overlays

[Stein Rørvik]

I need to control whether or not the font drawing gets antialiased for image overlays created by a macro and then flattened.
This seems to be controlled by the settings defined under Options - Fonts, but I can't find any way to change this from a macro. The macro recorder records nothing if I do changes here. I also cannot find anything about this in the macro functions documentation. Does anyone know a workaround?

Good day Stein,

what about:
"setFont(name, size[, style])
Sets the font used by the drawString function. The first argument is the
font name. It should be "SansSerif", "Serif" or "Monospaced". The second
is the point size. The optional third argument is a string containing
"bold" or "italic", or both.
The third argument can also contain the keyword "antialiased". For
examples, run the TextDemo macro."

Perhaps not perfectly what you want...

Yes this is what I want; but I forgot to tell that the overlay font I want to turn on/off antialiasing for is one created by the Scalebar command.

This illustrates what I want to do:

run("AuPbSn 40 (56K)");
setFont("SanSerif", 12, ""); //turn off antialiasing
run("Overlay Options...", "stroke=yellow width=0 fill=none set");
makeRectangle(50, 140, 10, 10);
run("Scale Bar...", "width=50 height=4 font=12 color=Yellow background=None location=[At selection] overlay");
Overlay.drawString("test", 50, 175);
Overlay.show;
run("Flatten");

The string "test" is flattened to a font without antialiasing (as desired),
but the scale bar font is always drawn with antialiasing. The scale bar aliasing is controlled by the setting under Options - Fonts which cannot be controlled by a macro.

Stein,

for whatever reason the very options setting is not stored in the
ImageJ-preferences file and the setting is always reset with every start
of ImageJ.

If the setting were stored, you could change the entry to the
preferences file...

In short, I've no idea of how to change the situation, except by
adapting the Java code of ImageJ.

Best

In the latest ImageJ daily build (1.51h13), the “Antialiased text” option in the Edit>Options>Fonts dialog can be set using the setOption("AntialiasedText”,boolean) macro function. The following is an updated version of the test macro that uses this new function.

-wayne

  run("AuPbSn 40 (56K)");
  run("Overlay Options...", "stroke=yellow width=0 fill=none set");
  makeRectangle(50, 140, 10, 10);
  setOption("AntialiasedText", false);
  run("Scale Bar...", "width=50 height=4 font=12 color=Yellow background=None location=[At selection] overlay");
  setFont("SanSerif", 12, ""); //turn off antialiasing
  Overlay.drawString("test", 50, 175);
  Overlay.show;
  run("Flatten");
