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

Hello rickharp, Welcome to Talkgraphics.

First which version of Xara software are you using? Your profile simply says graphics and that could mean any number of products

It is possibleto do this with a bitmap image in Designer Pro 8, and Photo & Graphics Designer 8 & 9 using a combination of live effects and the eraser tool. it's not a one click process and it's not perfect but it's not hard to do.

Step 1 : clone your cyclinder. flip the clone and set it in place for the reflection. align it at the middle don't worry about the edges yet you are going to fill those in.
Step 2: Clone the original cyclinder once more but don't flip it this time.
Step 3: Deselect your clone and use the shape tool (or the Pen tool) to trace a line along the bottom of the cylinder.
Step 4: Nudge the line up as far as you can with out it touching the bottom of the label and select both the line and the new clone and Ctrl + 4 to slice. The new clone is now sliced into 2 pieces. discard the top and keep the bottom.
Step 5: Pull the remaining bottom down on top of the inverted image and align the top edge of this with the bottom of the original.
Step 6: With this top piece selected go to the live effects tool, click new, and from the distortions filters select liquid colour. Gently distort the bottom of the image by using the draw brush and drawing the bottom edge downwards on either side. dont distort it too much. click ok to apply the filter and return to the main page.
Step 7: Use the eraser with a very soft setting to blend this bit with the inverted image underneath. Select both parts of the reflection and group
Step 8: with this group selected use the live effects again this time apply a gaussian blur filter (Soften filters> Gaussian blur)
Step 9: Last step! apply a linear transparency to finish it off.

I've attached a quick example using your posted image it's not perfect as I put it together quite hastily but it'll give you and idea how it will look.
