 Jim,
Here is a macro that uses "Process/Filters/Gaussian Blur 3D...".
It is less general than Gabriel's version, but it may be possible to update the macro to work like that.

Bob

 requires("1.45f");
xsig = 5;
ysig = 5;
run("Copy");
while(true){
  Dialog.create("Blur x-y");
  Dialog.addSlider("X sigma:", 0, 256, xsig);
  Dialog.addSlider("Y sigma:", 0, 256,ysig);
   Dialog.show();
    xsig = Dialog.getNumber();
    ysig = Dialog.getNumber();
    run("Paste");
    run("Gaussian Blur 3D...", "x="+xsig+ " y="+ysig+" z=1");
}

 ImageJ community -

In an attempt to demonstrate "stigmation" adjustment on a SEM (scanning
electron
microscope), for an on-line class, I am looking for a "stigmation plugin or
filter".

Since in "lock-down", I am looking for a "quick-fix" do demonstrate
astigmatism
in a previously collected 8-bit SEM image.

Meaning, I want to preferentially blur an image in the horizontal (X)
direction.

If that is possible, then I would also like to do that in the vertical (Y)
direction.

If that is possible, then doing that with "sliders" would be ideal.

Any ideas, suggestions, or links/URLs to previously posted work.

This does not need to be "technically correct".  I am looking for a
pseudo-astigmatism.

thanks and kind regards,

- Jim Quinn
