Java code for redirecting to original image under set measurements

[Rohitesh Gupta]

Hi Guys,

I am struggling to find out how to write a java code for setting original image in "redirect to" under the "set measurements" tab. Basically, I want to create a plugin using this code. Could anyone help in this direction ? The original Java code I recorded using "Record Macro" on imagej but that creates a code for specific image file. I want to create a generic code which can run on any image file. Hoping that i am making sense here, please let me know.

Thanks,
Rohitesh

Please study this code:
https://github.com/imagej/imagej1/blob/master/ij/plugin/filter/Analyzer.java

“ImagePlus redirectImage”
 is what you are looking for.

Good luck.

Thanks for your email. But, is there a better way to do this ? Any more suggestions.

I am not sure what you mean by “better”, but another way to check this is
through images api:
https://imagej.nih.gov/ij/developer/api/ij/plugin/filter/Analyzer.html#setRedirectImage-ij.ImagePlus-


   - setRedirectImage

   public static void setRedirectImage(ImagePlus
<https://imagej.nih.gov/ij/developer/api/ij/ImagePlus.html> imp)

   Set the "Redirect To" image. Pass 'null' as the argument to disable
   redirected sampling.

It’s quite clear and simple to use this function. Just assign the ImagePlus
instance of your original image as the input. Give it a try.

On a side note:
You didn’t share your code, and at least to me your description of the
problem was not clear. Therefore, help or suggestion can be limited. It’s
also not clear to me whether you want to create a plugin, a script, or a
macro. On one part you said you trying to make a plugin, and on another
part it seems like a macro. You didn’t mention which language you set the
macro recorder to, plus what code generated either. Purely guessing from
the context, a macro (in imagej macro language) should be sufficient to
fulfill what you want to achieve. Then you don’t even need to worry about
the java code .

Good luck.

Thanks for the help. I will try this in the code.
I am new to JAVA and so really don't understand the language that much. May be I will give it a shot and see if anything works out. Is there a way to check line by line execution of the code ?

I am attaching herein java code for your reference that was generated after recording macro.

If you could help in these aspects that will be really great:
1) Making ROI more flexible such that if there is a rectangular image then rectangular Roi covering the 95% of the image is selected. If there is circular image as in the case of agar plate, then Oval ROI covering 95% of the image can be selected.
2) Making redirect option more generic such that the grayscale image opened on imagej is selected in the redirect option.

I am new to java and plugin making process, so certainly will need help from the community in this regard. Thanks a lot Ziqiang Huang! Kudos!

Thanks a lot,
Rohitesh
