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
