Adobe has updated Acrobat XI and Reader XI to version 11.0.02 solely to improve the security of the two apps. The updates address critical vulnerabilities in versions 11.0.01 and earlier, vulnerabilities that could enable an attacker to take control of your system (detailed over at The Next Web). The update for Acrobat XI is just 11.9 MB; meanwhile you can choose between the delta updater (25 MB) or the full installer (76.6 MB) for Reader XI. Additionally, Adobe recommends that users of older editions of Acrobat and Reader update their software as well, with Acrobat getting version 10.1.6 (13.5 MB) and version 9.5.4 (10.8 MB). If you can’t update to Reader XI 11.0.02, you can similarly choose version 10.1.6 (17 MB) and version 9.5.4 (5.4 MB for Intel, 5.6 MB for PowerPC). ($449 new for Acrobat XI Pro, free updates)
Find Text Leading from Acrobat PDF
Ever have to recreate a document from an Acrobat PDF? You can find out most everything about the text by using the Object Inspector, except the leading. Well, here's a cheesy way to figure it out. Open the PDF in Illustrator (you just need one page). Release any and all clipping masks. Draw a guide at the baseline of the first line of text, and one on the line below. Now, Option-drag the first line to make a copy, and position it exactly next to the original first line at baseline. Then put a return anywhere in the copied line. Now adjust leading of the copied lines, so that the second line of copy rests on the baseline of the second line of the original. Now you know your leading.
Or you could buy expensive software to find the leading. Your choice.
