I've read through your code and can't seem to figure out how to use it
for my needs. For one, it looks like your guideline jumps from one
region to the next, and I would like mine to act like the ginput lines
(continuously following the cursor, on and off axes).

In my program, I have 3 linked axes that show the same image in
different forms: one is the full image, one is a thresholded binary
image, and the third is an overlay of the two. The binary and overlay
are zoomable, while the full image shows where you are zooming (if you
choose to do so).

I have multiple instances in which ginput is used for various image
editing functions, but as I have previously mentioned, the
fullcrosshair from the ginput does not stand out enough for me or
users of my program.

Your datamatrix is the closest thing that I've seen to what I am
looking for. How can I go about creating a separate ginput function
that uses the ginput functionality and uses a customizable crosshair
as you have created?

Thanks for pointing me in your direction, but I am still lost.
