In Photoshop, if I have a layer with a style such as a drop shadow, and I click on Image > Trim, I can crop the canvas to the exact points where the drop shadow fades out. I want to do essentially the same thing in Illustrator. I have an object with a drop shadow. I select the object, double-click on the Artboard tool, and in the dialog that appears, from the dropdown menu, I select "Fit to Selected Art". This succeeds at cropping the canvas to the dimensions of the object, but but it also cuts off my drop shadow. My only solution has been to eyeball the cropping of my canvas, but I really want to be precise and automate this process. Does anyone know how to do this?
