Currently I'm writing an app that contains an image viewer. I
implemented zooming as follows:

Zoom in:
Long press; Then a zoom-in icon appears at your finger-location. Then
drag a rectangle (with aspect ratio of your screen) from your current
finger position to another position; Move your finger off the screen;
Then the selected rectangle will expand to the size of your screen,
with the contained image, effectively zooming in.

Zoom out:
Touching the screen shows a zoom-out icon on the bottom of the screen.
It'll stay there for about 2 seconds after you release the screen.
When touching and holding the zoom-out icon, you'll zoom out, until
you move your finger off the screen.

A short press and then moving your finger will allow you to move the
image under your finger.
