Problem with IJ.run("Threshold...")

[gadea]

Hello, I'm developing a plugin, and I need to use the method Huang for thresholding. But when I try doing:

IJ.run("Threshold...", "Huang Apply")

nothing, the window is open but the method it isn't runned.

I have tried with:

IJ.run("Threshold...", "method='Huang'")
IJ.run("Threshold...", "threshold='Huang'")
and IJ.run("Threshold","Huang'") too, but nothing.

I hope you can help me.

Thanks in advance!

Gadea

Hello,
try

setAutoThreshold("Huang");
run("Convert to Mask");

You can use the macro recorder to find out how to apply macro commands
(menu Plugins>Macros>Record)

Hi Gadea,

using the Macro recorder (Plugins>Macros>Record...), switching to
'Record: Plugin' and then executing Image>Adjust>Threshold, I got the
following code that should do what you expect:

IJ.setAutoThreshold(imp, "Huang");

Hth,
Jan

to solve issues like this, just use the built-in macro recorder:

1) open your image
2) record a new macro (Plugins -> Macros -> Record)
3) switch from "Macro" to "Plugin" in the recorder window
4) open the Threshold dialog (Shift-Ctrl-T) and select your values
5) click Apply

The corresponding Java commands are now shown in the recorder window.

Cheers
~Niko

Hi Gadea,

You can set the macro recorder to record as plugin. Please see attached image.

Below are the output from the recorder when it was set to record "Plugin":
IJ.setAutoThreshold(imp,"Huang");
IJ.run(imp, "Convert to Mask", "");

Best Regards,
John
