Getting cursor location upon mouse click...

[Mark McNabb]

Hi if anyone could help me on this that would be great!

I am trying to set up a macro in order to analyse iem gold labeled
micrographs.  What I need to do is click on a location in an image, and then
have the x,y value of the cursor at the time of the mouse click be put into
an x,y variable pair in the macro.

I have seen the mouse-listener plugin but don't know if that is appropriate
or how to use it in a macro.

Any ideas?

Thank you!

Mark.

Use a tool macro. Here is an example:

    macro "Color Picker Tool -C44f-o4499" {
         getCursorLoc(x, y, z, flags);
         print(x, y, z, getPixel(x,y));
    }
