Subject: Re: How do I set Pencil Width, Brush Width, or Eraser Width from within a Java Plug-in?
Pencil, brush, eraser tools are macro-based tools defined in the startup
macros file StartupMacros.txt or in the DrawingTools.txt macro set.
For example the paintbrush tool options macro is:
macro "Paintbrush Tool -
C037La077Ld098L6859L4a2fL2f4fL3f99L5e9bL9b98L6888L5e8dL888c" {
getCursorLoc(x, y, z, flags);
if (flags&alt!=0)
setColorToBackgound();
draw(brushWidth);
}
The brush width is currently only set when the macro set is installed or
when you run the "Paintbrush Tool Options..." macro.
macro 'Paintbrush Tool Options...' {
brushWidth = getNumber("Brush Width (pixels):", brushWidth);
call("ij.Prefs.set", "startup.brush", brushWidth);
}
You can modify the paint brush tool macro so that it reads the preference
everytime it is started:
macro "Paintbrush Tool -
C037La077Ld098L6859L4a2fL2f4fL3f99L5e9bL9b98L6888L5e8dL888c" {
brushWidth = call("ij.Prefs.get", "startup.brush", "10");
getCursorLoc(x, y, z, flags);
if (flags&alt!=0)
setColorToBackgound();
draw(brushWidth);
}
Then you can have your Java Plug-in modify this preference as shown in:
http://rsb.info.nih.gov/ij/plugins/preference-demo.html
Ideally, you could have your plugin installing it's own version of the
desired tools, so that you do not have to distribute e.g. a modified
startup macro set with you plugin.
ij.plugin.MacroInstaller.install(string) does this.
