Hello,
I am trying to upload a photo, re-size it so that the smallest size (width or height) is 100px, and then crop the re-sized photo to 100px x 100px from the center. I am doing this to create square thumbnails while still trying to get as much of the photo as I can in the thumbnail. For some reason the photo I am getting is mostly black with a small area of the photo in the upper left corner (The photo I am uploading is 152px x 264px). My code is below. Can anyone help me out with this and see where I am messing up?
Code:
