10.5: Annotate non-PDF (raster) images in Preview Apps
As is known, one can annotate PDF documents by means of Mac OS X standard Preview application. It turns out that the same functionality is available for raster images also, but for some reason, it's hidden by developers.

Open your picture in Preview, then select View » Customize Toolbar. Drag the Annotate tool to your toolbar. Then just choose the type of annotation you want to make from the newly-created toolbar element, and use the mouse to add it to your picture. You can also use following modifiers:
  • Press the '+' or '-' keys to increase or decrease line thickness.
  • Choose Tools » Show Colors and use the color wheel to change the color of the selected object (including notes).
  • Choose Tools » Show Fonts and use the fonts panel to change the text note font.
This functionality could be useful when commenting screenshots.

[robg adds: The Tools » Annotate menu item is grayed out when you have raster images open, so I'd always assumed it just didn't work. But it does -- as long as you use the Annotate toolbar item instead of the menu. The line thickness modifier keys also work without being shifted -- so you can just press '-' and '=' to change the thickness. Somewhat oddly, when annotating a PDF, you can use the color tools, but not the thickness tools nor the fonts panel.]

I followed the instructions -- but all i can do is annotate using the oval tool: the pulldown menu next to the oval doesn't reveal a submenu. Did you have this problem? Is there a secret?

Hold down the mouse button over the newly created a annotate toolbar menu and the 4 types appear (oval, rectangle, note, line)

10.5: Annotate non-PDF (raster) images in Preview
Authored by: davidm on Jul 08, '08 09:41:35AM

Anyone know how to put a text box inside a PDF in Preview (i.e., not a "note," which puts a text box or comment outside the page and a little speech-bubble placeholder inside the document itself)? This was something you could do in Tiger Preview that I used all the time.

Note: I'm aware that you CAN actually do this for a jpg, just not for a PDF. For a jpg, the "note" function in the annotate tool actually creates a text box on the image itself and not in the margin.

I've been using Formulate Pro for some time now to "write" on PDFs. It's a simple app that works pretty well, and even at this stage of development I've not had it crash on me. http://code.google.com/p/formulatepro

Very cool hint.

Stupid question: what is the purpose of "Annotate" "Oval" or "Square"? How do I use these sorts of things.

I wish I could have the ability to underline and highlight PDFs in Preview, not just annotate. Acrobat is so bloated that I don't really want to use it all the time, but it's the only PDF reader that lets me mark text (underline, highlight) in a manner similar to how I would mark a printed book.

You can underline or highlight text with Preview in 10.5. Just select some text and go to the "Tools --> Mark Up" menu (or add the controller to the toolbar)

Acrobat is better about selecting text in only one column of a multicolumn PDF, though, so I still use it for most highlighting.

Oh, nice. That's almost a reason to upgrade from 10.4. I was hoping to just wait for another computer, though.

Thanks for the info!

Skim
Authored by: Black on Jul 09, '08 08:32:59AM
You should check out Skim. It is designed for things like quickly highlighting text. It is a little clunky in two-column mode, but judicious use of option-dragging works well enough. I like the fact that Apple provides Preview, but for all of my academic paper needs, I've converted to using Skim.

For form fill and annotations, check out PDFpen. Easy, no-brainer, small-footprint. Works flawlessly.

10.5: Annotate non-PDF (raster) images in Preview

I am seeing some strange behavior with Preview when trying to annotate non-PDFs. I can add the toolbar button, and switch between tools, but nothing happens on-screen.

Additionally, after I try to do something with the annotate tools, when stretch the window wider, I get weird garbled images of the windows behind the image I am working on.

I also noticed that Preview attempts to connect to the Internet when using the Annotate tools, I see this with Little Snitch's popup window.

OK I figured this one out myself:

Turns out it was caused by a 3rd party color picker I had installed some time ago: Mondrianium (uses Adobe Kuler as a color picker).

Deleting it fixed everything, and just to test I installed the newer version, which worked as well.
