I need a script to determine the size of the spine for the book cover and than create that canvas with that spine size with bleed. I need to see the guides for bleed and the guides to where the spine is. I need a dialog box to where we can set the size of the book, the bleed size and the number of pages. From there it needs to generate a canvas based on that following criteria?
I'm going to need to have access to change the sizes and add new sizes and book style?
