 Richmond,

Take a look at the various examples of  stack 
<http://www.sanke.org/Software/SnapshotTestStack.zip>.

To get the transparency of a graphic you could use:

"export snapshot from rect(rect of grc "polygon") of grc "polygon" to 
img "placeholder" as PNG"

and - if necessary - when you want to include other properties of the 
polygon area like gradients or text on the polygon, then take another 
snapshot with the syntax

"export snapshot from rect(rect of grc "polygon") of this card to img 
"placeholder2" as PNG"

and set the alphadata of img "placeholder2" to the alphadata of img 
"placeholder".

Best regards,

Wilhelm Sanke
