I need to create an overview box for a static image, and I had a few ideas of what I could do but I am very new to Processing and wanted to hear from the community. For this static image, I have created a zoom and pan function, and was thinking about putting a smaller version of the picture in the corner, and having a box with no fill represent the camera parameters, but this seems like something that would yield a lot of small problems and be time consuming. Would anyone have a better idea of how to achieve this?
