I would like to know how to change the Image Source in codebehind.

I am using this library to use SVG as background for InkCanvas.
It's working very well.

I load multiple SVG files at once
I want to replace an image based on user input.

To do that, it seems that you have to create an SVG image with the absolute file path in the backend and apply it every time.

But I don't know how to apply this library.

May I know how to apply this as an image when I open a specific SVG file with OpenFileDialog ?

Did I express my intentions correctly?
Could you please review the method using the library as well?

ImageSource = svg:SvgIcon ...

Is this correct?

 private async void btn_OpenFile_Click(object sender, RoutedEventArgs e)
        {
            openFileDialog = new OpenFileDialog();
            //openFileDialog.Filter = _OpenFileFilter;

            if (openFileDialog.ShowDialog().Value == true)
            {
                string filePath = openFileDialog.FileName;

                string fileName = System.IO.Path.GetFileNameWithoutExtension(filePath);

                SVGImage.SVG.SVGImage image = new SVGImage.SVG.SVGImage();

                image.UriSource = new Uri(filePath, UriKind.Absolute);

                inkCanvasImage.ImageSource = (ImageSource)image.ImageSource;

            }
        }

<InkCanvas x:Name="inkCanvas" EditingMode="None"
                   Grid.Row="0">
            <InkCanvas.Background>
                <ImageBrush x:Name="inkCanvasImage"
                            
                            ImageSource="{svg:SvgIcon Source=1.svg}"
                            Stretch="Uniform">

                </ImageBrush>
            </InkCanvas.Background>
            <InkCanvas.RenderTransform>
                <TransformGroup>
                    <ScaleTransform x:Name="inkCanvasScale"/>
                    <TranslateTransform x:Name="rectTrans"/>
                </TransformGroup>
            </InkCanvas.RenderTransform>
        </InkCanvas>

Is this correct?

"Correct" may not be the right word here, since this will work but not what you might need to do.
SvgIcon is a markup extension not a control, so the Image control will activate this whenever it needs an ImageSource.
However, SVGImage is a control, you do not want to create a control just to get an ImageSource, that is why I added the
SvgIcon and SvgIconConverter.

Why SvgIconConverter?
WPF markup extensions have to extend the abstract class MarkupExtension (there is no defined interface) which does not derive from DependencyObject (like most WPF classes), so you cannot do WPF binding on markup extensions.
So to be able to support the binding, SvgIconConverter also implements IValueConverter to make it a WPF converter based on markup extension, which also makes the XAML syntax different.

See the sample below for demonstration of the SvgIconConverter; illustrating binding to resources, local files, web files and list view. For your use case, see the third tab PageOther.

Thank you for your kind reply.

I have a few additional questions
May I proceed?
