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.

iSight Eyes iChat AV

If you're the type of person who bemoans the impersonal nature of email or text messaging, Apple wants to offer you a little face time. At the Worldwide Developers Conference (WWDC) today, Apple introduced iChat AV, adding audio and video conferencing capabilities to its iChat instant messaging application. A public beta of iChat AV is now available as a 3.6 MB download. Also introduced was the iSight, a compact video camera that takes advantage of iChat AV's audio/visual capabilities; the iSight is available now.


iChat AV supports any FireWire DV camcorder or webcam, according to Apple, and automatically configures itself during installation. Other iChat AV users appear in the Buddy List with audio or video icons beside their names to indicate the type of connection that's available. In addition to a default window size of 352 by 288 pixels (which can be resized during video sessions), the software also includes a full-screen mode. iChat AV will be included with Mac OS X 10.3 Panther when it is released later this year. Those who wish to stick with Mac OS X 10.2 Jaguar and above can upgrade to iChat AV for $30 after 31-Dec-03.

That said, Apple would prefer that you not only upgrade to Panther, but also purchase the $150 iSight, a video camera designed to be mounted on Apple displays and laptops. The iSight includes an auto-focus lens with 640 by 480 resolution, a lens aperture of F/2.8 to collect more light in poorly lit situations, and a video frame rate of up to 30 frames per second (fps). For audio, the iSight includes a dual element noise-suppressing microphone. It's also small and light, weighing in at 2.5 ounces (63.8 grams).


We'll have more on iChat AV and the iSight in a future issue, but in our preliminary testing of iChat AV with various microphones and FireWire webcams, the application performed well, with the audio being both surprisingly clear and full-duplex.
