Reduction Images--AS--InDesign CS2

Hi All,

How can I get reduction of images through applescript. I have place an image in InDesign document and shrink the picture frame I would like to calculate by how much % it reduced from it’s original size.

Thanks

You can get the original size this way (and the dimensions of the new frame from InDesign, I presume):

set I to choose file
tell application "Image Events" to set D to dimensions of (open I) --> list of two {width, height}
