There are many times you might want to knock out the background of a particular image on your Mac. Typically, I pop into Photoshop or Fireworks to use the Magic Wand tool to select all the white space of that image, and delete from there. These programs cost hundreds of dollars, though. Isn’t there a free way to do this?
It turns out that Preview, the free image & PDF viewing (and now editing) app that comes with OS X will do the very same thing, without you having to spend an extra dime on image editing software. Here’s how to do it.
CES 2013, the world’s biggest cornucopia of cutting-edge gadgetry, kicks off in Las Vegas in under a week, and as always, Cult of Mac’s team of writers will be at all the booths, announcements and parties that matter, getting you the scoop on what’s coming up in the world of tech.
There’s a lot for any Apple fan to get excited about in the run-up to CES, but this year, we think you want to pay a lot of attention to what’s coming out of Las Vegas in relation to home automation. Chances are, everything from your oven to your lights to your thermostat are going to be controlled by your iPhone in just a few years time… and even Apple wants in on the action.
Preview is a catch-all file viewer, handling a variety of image formats as well as the ubiquitous portable document format, otherwise known as the PDF, which was introduced by Adobe in 1993, and was released as an open standard in 2008. One thing Preview has had trouble with, until now, has been adding extra pages to a PDF document.
Not anymore, as the Mountain Lion version of Preview will let you add pages to PDF documents on the fly. Here’s how.
Apple continues to test Facebook integration for Mountain Lion.
Apple has seeded a new OS X Mountain Lion 10.8.2 build (12C35) to participants in its AppleSeed program, continuing its testing of Facebook integration. Though it states that there are no known issues with this update, the Cupertino company is also asking users to focus on Messages, Game Center, Safari, and Reminders.
You may already know that you can right click on any file in the Finder and choose “Open With” from the contextual menu. This gives you a list of all the apps Mac OS X thinks can open that file. An image file, for example, will show Preview (default), Firefox, Google Chrome, and any image editing app that you may have on your system, like Adobe Photoshop or Fireworks.
You may also know that tapping the space bar after clicking on any file in the Finder, Open and Save dialogues, or in Mail app, will give you an instant preview of that file. This feature is called Quick Look, and it’s been in OS X for a while, now. iTunes will play their audio content, images will zoom to their actual size, and videos, if you have the right codex on your Mac, will play in a little pop up window.
What you may not know is that these two features can be combined now in OS X Mountain Lion.
Mac OS X 10.8 Mountain Lion has over 200 new features. One of them resides in the Preview app, Apple’s answer to all of our PDF and image viewing needs. Mountain Lion tweaks the toolbar a bit, adds a new one, and allows a simpler annotation process. There’s also a new sharing option to go along with the highly publicized Documents in the Cloud initiative.
Apple’s presentation software Keynote is, in my opinion, a fantastic application for making presentations on your Mac. It’s easy to use, presents a unified metaphor for designing slideshow presentations, and makes using rich media a very simple process. Unfortunately, not everyone who uses a Mac will have Keynote, as it seems that Office is the de-facto standard in many businesses and computers.
Fear not, however, as viewing Keynote files on a Mac is super easy, even if you don’t have the Keynote app itself, which is also an affordable and very worthwhile $10 in the Mac App Store. Here are three ways to do just that.
Let’s face it, rotating a bunch of images can be a time or a money sink. You either have to open each image one at a time, rotate them manually, and then seave them, one at a time, or you need to purchase an image editing program like Photoshop or Fireworks. And don’t get me started on figuring out how to do this in Gimp, a free, open source image editing program.
Turns out, though, you’ve already got all you need right on your Mac. Batches of image can be rotated all at once with Preview.
Command-Shift-3 is so last year. Using Grab to, well, grab shots of your screen is blasé. If you’re really hip, you’ll use today’s tip to get your screenshots and thank us for it in the comments below.
