title: Programmatically slicing an image in Fireworks and exporting on whole transparent background, to form a layering effect
body: <p>I have a large image made up of lots of smaller ones that I want to slice up and export. This can be done with slices, but unfortunately this will export only the cropped image -- I want the whole canvas to be present for each export, with the slice in place, meaning I could overlay each individual export and have the original picture, but in separate layers.</p>
  
  <p>This can't be done with the Fireworks GUI. How can I do this programmatically?</p>
