Looking Forward to Window Clippings 3: Alpha Blending

Over the next few weeks I will be highlighting some of the improvements and new features that you can expect from version 3 of Window Clippings.

First up let me tell you about the improvements to the algorithms for capturing the alpha blending produced by desktop composition (Aero). The big news is that it is able to capture the alpha channel even when significant animation is present. In previous versions Window Clippings would revert back to producing an opaque image if any animation occurred during capture. I have always focused on producing the most authentic images possible by capturing what is on screen with the highest accuracy. With version 3 I’ve made further improvements to produce pixel-perfect images with even greater levels of color accuracy.

Take a look at the image below produced by Window Clippings 3 (and viewed in Paint.NET to highlight the alpha channel). Here you can see Google Chrome and Windows Media Center both playing HD videos. There’s also a window with a standard animated progress bar. Finally, Internet Explorer 9 is flexing its muscles with an impressive 60fps demo of HTML5. All of these windows would have caused previous versions to produce an opaque image, but not anymore!


That’s it for today. Stay tuned for more highlights from the upcoming Window Clippings 3!
