Transparent/, glass-like image view

[M. S. Hrishikesh]

Hi

I would like to create an image view that is like glass. It should show the contents of the view below through itself (distorted like glass).

The specific situation:

I display imageView1 which shows a picture or nice background. On top of it I want another imageView2 (smaller and can be moved around) that is  a glass slab. When looking through imageView2 the user should see a distorted view of imageView1 (like viewing through a glass bottle or glass slab).

I have tried goggling but I only found ways to create "glass buttons" in photoshop. These are pretty cool looking buttons that look like they are made of glass but they do not really serve my purpose.

I realize this is probably a hard goal to accomplish. At this point I have no idea where to start. Could someone point me in the right direction.

I think this can be done with OpenGL/OpenGL ES (but I don't know those technologies). Is that the only way?

Thank you

Hrishi

If I understand correctly, you can probably accomplish what you desire by using Core Image and, in particular, either the CIGlassLozenge or CITorusLensDistortion filters.

Check-out the Core Image filter CISoftLightBlendMode. If that won't work, I'll bet there's a CI Filter that will.
