If you have a gerber file then translating to bmp file or something else, then you might want to consider using a product called ViewMate.
I like it. I can view gerber files, drill files, make some edits.. And it can tile your design, mirror, rotate, create negative image...
Do a search for ViewMate. If you are cheap, get their free version.
