When zooming in on an image today there is no feedback when the image:
- fills the screen (image 2)
- the image is actual size (image 3)
When the image fills the screen there should be a small “snap” and/or be sticcy that shows the user that the image is to the edges of the screen.
Likewise when the image is actual size.
Double tapping on an image zooms in 25% and centers where the user taps.
A single tap zooms out like it does today. (image 1)
