Smile has updated PDFpen and PDFpenPro to version 6.0.2, dramatically reducing memory usage and adding an option to turn off Auto Save and Versions (found in the General pane of PDFpen’s preferences). The update brings several requested form-related changes, including improved tab ordering with automatic form creation, setting a multi-line property when automatically creating tall form fields, reverting to the default font when automatically creating form fields, and fixes for unspecified issues when saving PDF forms. Additionally, both editions fix issues with applying foreground, background, and stroke colors, and ensure that document permissions are respected when inserting page numbers. As of this writing, neither PDFpen nor PDFpenPro have been updated to version 6.0.2 in the Mac App Store. Upgrades from a previous major version of PDFpen or PDFpenPro cost $30 via Smile, but are free to those who purchased on or after 15 October 2012. If you want to upgrade to PDFpenPro from a previous version of PDFpen, the price is $40. ($59.95/$99.95 new with a 20-percent discount for TidBITS members, free update from version 6.0, 49.4/50.2 MB)
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.
