How to select a point with coordinates with a GUI?

I would like to put an image on the screen, and select two points with the mouse in a GUI window. Is it possible? Moreover the image size is very big - cannot fit into the screen - so rescaling or scrolling is needed.

[Mr M.]

these are standard functions or in a specific toolbox?

• Import the image with imread
• Display it with image, imagesc or imshow. These commands scale the image to the available space already.
• If you want a scrolling instead, https://www.mathworks.com/help/images/ref/imscrollpanel.html imscrollpanel would help. Further solutions can be found in the FileExchange: https://www.mathworks.com/matlabcentral/fileexchange/?utf8=%E2%9C%93&term=image+scroll
• Use ginput to select points

You can search in your local documentation or online at the MathWorks website, if the commands belong to the standard toolbox.
