C#/UWP app that crops images

We need a simple application to streamline image cropping. The functionality would be as follows... jpg images would be placed in a folder called "Images" (could be in the same folder that application runs from). This is done manually, not by the application In the same folder would be a folder titled "Cropped". Again this would be created manually not by the application Upon loading Application would display the first image in the "Images" folder User would make 4 mouse clicks on the image to define crop rectangle. Coordinates should be displayed somewhere on the application form (preferably at the very top, attractive UI is not a concern). Once 4 points are defined user would click a "Next" button on form. That would... * crop the image * save the cropped image in the "Cropped" folder * save the 4 points to a csv file * load the next image out of the "Images" folder Names in the Cropped folder should just be sequential numbers ([login to view URL]). When using application user will make sure the Cropped folder is empty Process repeats for every image in the "Images" folder That should be the process. There should also be a "Clear" button to allow the user to clear all coordinates for current image if they mis-click. That's it. Please let me know if you have any questions
