This will bring up a preview window and some extra controls (image attached)

Your options will be:



Number of Levels - The number of colors that will be used to make up the image. The stencil was a 3 layer stencil, but if I set the levels to 3 it just became too difficult to make out.

Edge Simplicity - Higher the number the straighter the edges become but you lose detail.

Edge Fidelity - experiment with this one, I dont think it makes enough difference when you have the x-acto in your hand though
