ImageResizer: how do you use Instructions? - imageresizer

Question

The documentation for ResizeSettings says:
"Replaced by the Instructions class"
http://documentation.imageresizing.net/docu/ImageResizer/ResizeSettings.htm
The documentation for Instructions says:
"The successor to ResizeSettings."
http://documentation.imageresizing.net/docu/ImageResizer/Instructions.htm
However, I cannot figure out how to use Instructions instead of ResizeSettings. I've tried
Google
Documentation (documentation.imageresizing.net)
Looking through the Object Browser for uses of Instructions
Searching ImageResizer.dll in .net Reflector for uses of Instructions
Decompiling all of ImageResizer.dll and searching for through the resulting code.
If Instructions replaces ResizeSettings, then how do I use it instead of ResizeSettings?
=== Edit - more detail:
This a way to use ResizeSettings:
public static Bitmap Resize(Bitmap bitmap, int maxHeight, int maxWidth)
{
var setting = new ResizeSettings
{
MaxHeight = maxHeight,
MaxWidth = maxWidth,
};
return ImageBuilder.Current.Build(bitmap, setting);
}
Reading that Instructions was a replacement for ResizeSettings, one of the first things I tried was this: (I was hoping ImageBuilder might have an overloaded Build method)
public static Bitmap Resize(Bitmap bitmap, int maxHeight, int maxWidth)
{
var instructions = new Instructions
{
Width = maxWidth,
Height = maxHeight,
Mode = FitMode.Max
};
return ImageBuilder.Current.Build(bitmap, instructions);
}

In an unexpected turn of events, the documentation is ahead of reality.
You can use the Instructions class, but for now you must convert it to a ResizeSettings instance first like so:
.Build(source, dest, new ResizeSettings(new Instructions("width=20")));
In the next major release, this will accept an Instructions class directly.
