Adding an namespace effect to an Image programmatically

Question

I am trying to add a custom greyscale effect to an image. the effect via nuget: https://www.nuget.org/packages/GrayscaleEffect/

I am trying to add the effect to an image like so:

Image.Effect = new GrayscaleEffect { };

And I am getting an error that tells me that GrayscaleEffect is a namespace, and I can't use it like so. How can this be done?

Answer 1

The GrayscaleEffect class is defined in the GrayscaleEffect namespace:

Image.Effect = new GrayscaleEffect.GrayscaleEffect
{
    DesaturationFactor = 1.0
};

As Ian reminds me, you can also add using GrayscaleEffect; at the top of your C# file, to avoid having th explicitly mention the namespace every time you reference the class:

using System.Windows;
using System.Windows.Controls;
using GrayscaleEffect;

//...snip...

Image.Effect = new GrayscaleEffect
{
    DesaturationFactor = 1.0
};

If you type GrayscaleEffect. , with a dot or period after the namespace name, intellisense will present you with a list of the types defined in that namespace:

This is generally true, and very useful.
