I am trying to create sliders that will serve to manipulate the red green blue values of an image displayed on axes. So far, my code is able to open up desktop (with a click of the load file pushbutton), select an image, and display that image on the axes.
How should i create the sliders (one slider for each of the three colors) so that they can adjust the image's rgb values? see attached files>
