Export pdf actual size
 

When I export a document that is 960px wide to pdf, the pdf when viewed at actual size is quite a bit wider than 960px. Is there anyway to keep the document's actual width when exporting to pdf?

I am having the same problem. Any canvas larger than 8.5 x 11 seems to export to a PDF that is much larger than the dimensions of the original Omnigraffle canvas.

I just set the canvas on a document to be 12 inches by 12 inches (864 pixels on a side), then did an export to PDF and opened the resulting file in Preview on my Snow Leopard system. Got a ruler out and measured the size of the window after selecting View->Actual Size and it turned out to be slightly [b]under[/b]sized at 11 13/16" across. That is much larger than the window shown in OmniGraffle, and I suspect that might be the source of the confusion. Bring up the ruler in OmniGraffle and get out a ruler of your own for comparison. On my machine (27" iMac) 12" on the OG ruler only takes up 7 7/8" on my ruler, which is what one might expect on a display that is about 109 ppi instead of the nominal 72.
