Capture Non-Rectangular Windows With Transparent Background

When you take a screenshot of a non-rectangular window (e.g. iOS Simulator), the background behind the window is also captured. Other screenshot utilities capture these windows with a transparent background. See attached comparison.

Do you want the bezels on the phone or just the content? 

If it's the latter then, if you use the Fuse app on your phone, you can capture the screen on your phone and send it straight into SnagIt.  Like this:



It's freakishly good.

Another possibility is to actually capture an area larger than the phone. But before you do, ensure the phone image is in front of something like an open instance of Windows Notepad with nothing appearing on the Notepad area. That would give you a nice clean background with which to work. After you capture the area, just flood fill the white background with transparent. Then use the Auto Trim to pull all edges in to the surrounding phone image.

I could do that, but it’s an awful lot of hassle I’m never going to do when other screenshot applications handle non rectangular windows correctly. Click - paste - done.

Are you allowed to say on here what competitor tool you're referring to?

All other screen capture / annotation apps I've tried handle non rectangular windows, from the very simple screenshot only tools like Grabbit (https://itunes.apple.com/ie/app/grabbit/id427084249?mt=12) and Screener (http://cocoashot.com/capture.html), to full featured annotation tools like Nimbus Capture (https://nimbusweb.me/screenshot.php), AirSketch (http://www.cloudsketchapp.com),  LightShot (https://itunes.apple.com/ie/app/lightshot-screenshot/id526298438?mt=12) and Xnip (https://itunes.apple.com/ie/app/xnip-screenshot-annotation/id1221250572?mt=12).

Snagit's annotation features are the best. It's just missing this one feature!

Thanks for sending. The only one I've used out of these is Nimbus and I really like parts of it. And I guess you're right—it allows you to capture fragments or windows. I'm looking for something that allows a little more control. Usually, capturing a uniquely shaped element on a screen is more important than capturing the window. 

I think Snagit is the best, but I'd love something more lightweight that also has a Chrome extension. Nimbus is almost there but it lacks a few things, so I have to use both.

Thanks again.

I submitted similar feedback, but got zero bite. I want to capture bezels and all irregular shapes. Here's my post: https://feedback.techsmith.com/techsmith/topics/capturing-rounded-corners-and-other-irregular-shapes

Hi,

Good news, there is a way to do this in Snagit! It's a little hidden though, so what you want is our Mission Control capture option



Once you hit capture, all the windows will fly out and you just select the one you'd like to capture.

I'm guessing this is yet another Mac specific option not found in Windows?

Hi,

Mission Control is a macOS feature that we're tapping into, so in this case, yes. One thing you can do that works reasonably well is to take a capture of a window with a high contrast background behind it. Then you can use Smart Move in the editor to get just the window you're interested.
