Disclaimer -- As some of you may have noticed, I now write the Beating the System column for MacUser. I don't know what to disclaim, but since I'm identified as the editor of TidBITS at the end of those columns, it seems only right to mention it here. Writing for MacUser is different in that I have an approximately four month deadline for MacUser and a one hour deadline for TidBITS. That said, check it out and see what you think of my writing when I have a word limit and a professional editor.
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.
