Inserting a function in Edit/Selection/Enlarge numeric dialog box

[ayubsulong]

Dear ImageJ users,

I'm working with this macro,

--
//apm_oval_v3
//create oval for every slice of apm


dir1 = getDirectory("Choose Source Directory ");
dir2 = getDirectory("Choose Destination Directory ");
list = getFileList(dir1);

setBatchMode(true);
for (i=0; i<list.length; i++) {
showProgress(i+1, list.length);
open(dir1+list[i]);

run("Create Selection");
run("Make Inverse");
run("Enlarge...", "enlarge=0.01");
run("Make Inverse");
run("Enlarge...", "enlarge=-0.01");
run("Specify...", "oval");
// run("Enlarge...", "enlarge=-0.01*x");
run("Enlarge...", "enlarge=-0.01");
run("Clear Outside");
run("Invert");
run("Make Inverse");
run("Invert");


saveAs("Tiff", dir2+list[i]);

close();
 }

--

I have 800 circular images (few examples in attachment). As indicated with
the arrow,

command run("Enlarge...", "enlarge=-0.01"); will key in -0.01 in the
numeric window ENLARGE.

How do I insert a function (-0.01*3x) in that numeric window. Where should
i define the 'x' and the multiplication process. I got Macro error message
"Numeric value expected in run() function"

I'm new to ImageJ and any help would be appreciated.

Cheers,

Ayub

Hi Ayub,

you can set a variable to put the result of a calculation into a list of parameters:
  enlargeBy = -0.01*3x;
  run("Enlarge...", "enlarge=&enlargeBy");
As an alternative, use String concatenation:
  run("Enlarge...", "enlarge="+(-0.01*3x));

Hi Michael,

Many thanks for your quick reply. Can you please elaborate more on
setting a variable and parameters.

Cheers,

Ayub

Hi Ayub,

have a look at the documentation of the macro language:
  http://rsb.info.nih.gov/ij/developer/macro/macros.html#run

At the end of the section "Using run() to execute ImageJ commands", you will find a short description on how to put variables into the argument string of a 'run(...' command.

Hi Michael,

Thanks for initiating the spirit to dig in Java based macro.

This is what I needed,

//APM_oval
//the equation in Macro loop

sdir = getDirectory("Choose Source Directory ");
ddir = getDirectory("Choose Destination Directory ");
list = getFileList(sdir);
       

        setForegroundColor(255, 255, 255);
        setBackgroundColor(0, 0, 0);

                setBatchMode(true);
                for (i=1; i<list.length; i++) {
        showProgress(i+1, list.length);

        open(sdir+list[i]);

                                run("Create Selection");
                                run("Make Inverse");
                                run("Enlarge...", "enlarge=2");
                                run("Make Inverse");
                                run("Enlarge...", "enlarge=-2");

                                r = 355;

                                        r_prime=sqrt((r*r)-(abs(r-i)*abs(r-i)));

                                run("Specify...", "width="+2*r_prime+" height="+2*r_prime+" x=390  y=358 oval    centered");
       

                                run("Clear Outside");
                                run("Invert");
                                run("Make Inverse");
                                run("Invert");
       

        saveAs("Tiff", ddir+list[i]);

                        close();
        }
