How do you extract index values from the data tips function into a variable or an array?

I need the index value shown when I select a pixel of my image using the data tips tool.
I need to acquire all the index values of the pixels located within the white square box.
I would record 466.833, 405.573 and so on until I get all the index values of the pixels within the white square box.
Is there a way to extract all the index value data without manually recording them?

You can access it as such:
h = gca; %gca stands for get current axes
for i = 1:NumberofDatatips
h.Children.Children(i).Content %The child of the axes is the image and the children of the image are the datatips
end
Would you want to automate this process? If so, prehaps you can combine two functions such as getpts() and datatips().

No, it is the total number of datatips. If the only children are datatips, you could acquire the number with
length(h.Children.Children)
