How to make a cylinder (can) have a reflection as if it was sitting on glass

[tonylondon]

If all your label is vector, then you could apply an default envelope (Mould Tool) and edit the objects. But this will not work on bitmaps.

It is possible to warp a bitmap for an application such as this by using trace bitmap, using high accuracy settings. Afterwards you can convert back to a bitmap after warping if need be. I did produce an example but can no longer see how to upload images!
