If I am working with Bitmaps in fireworks their data behaves independently of the document area, in other words I can move a bitmap in and out of the canvas without losing any of its data. This gives me room to play about with part of the bitmap in visible areas.
But as soon as I crop the document, it crops all bitmap data to the confines of the canvas. All I want to do is make the canvas smaller but still have the full bitmap to 'play' with inside the smaller canvas. How do I crop a document without cropping all of its assets?
