The expansion of the page sizes is on the list for future FFCore enhancements.
Why? Since v1.6 (Acrobat 7.0) PDF supports page sizes up to 15,000,000 x 15,000,000 inches. PDF 1.6 has been released in 2004... Why are we still limited to 200 x 200 inches?
The 200X200 inch limitation is hard-coded in FFCore -- there is no switch to override the limit.
I need to impose PDFs for a large format inkjet printer up to 200 x 4,000 in (about 5 x 100 meters). When creating a new imposition preset I can add a user defined sheet size of max. 200 x 200 in.
How can I get a larger (longer) sheet size?
