I have images that I can drag around on screen. On these images, I want to be able to draw rectangles in predefined spots on each image (think like drag handles, although they will not be used that way). Whenever the image gets dragged somewhere new, I would like these rectangles to be drawn in the same spot on the image. This includes if the image is rotated too.
I have tried a number of different things but cannot get anything to work so I am hesitant to describe any of them. This was easy to achieve with Winforms but since I can't access a Paint method and it seems that the only way to set coordinates of a rectangle is Canvas.SetLeft(image, x), Canvas.SetTop(image, y) and these rectangles should be a child of the image, I'm finding this very un-intuitive.
How would I go about doing this?
