I tend to think of what you describe as dividing the page into tiles, with some tile size (usually the same as the page size), and the amount or percentage of over-lap. (And then you need to decide whether the user should designate the amount of overlap in millimeters or inches or pixels and which of these Cocoa expects.) And then you'd probably have to give it multiple rectForPage for each page you want to be tiled, one for each tile. I have not done this with Cocoa, so am only describing how I think of it in hopes of providing some insight and possible terms on which to search. Collating has to do with the order in which the separate tiles and pages of a document are printed. If you tell it to print it 3 times, page n will precede page n+1, and each copy will be "together". What order is proper for tiles is up to you, since I know of no widely accepted conventions. _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
