Paint.NET: How to Crop an Image into a 16:9 Aspect Ratio

How to crop an image into a 16:9 aspect ratio using Paint.NET.

Open the image in Paint.NET.
To check the aspect ratio, go to Image, then Resize.
Check Maintain aspect ratio.
Type 1920 for the first value.
If the second box is not 1080, then the image is not in a 16:9 aspect ratio.
Close the resize window.
Use the Rectangle Select tool in the toolbox.
In the menu bar, click on Normal, or use the drop down menu to select Fixed Ratio.
Type 16 for width and 9 for height.
Drag the rectangle to select a crop area on the image. The box will stay in a 16:9 ratio.
When you are ready, use the Crop to Selection button in the main toolbar, to the right of the cut, copy, and paste icons.
Go to Image and Resize again.
Check Maintain aspect ratio.
Type 1920 in the first box.
The second value should be close to 1080.
If it is something like 1081, uncheck Maintain aspect ratio and change it. Either way, one pixel will not make a difference.
