Question

I am developing a custom Image control in WPF .NET 3.5 and Visual Studio 2010.

In WinForms the PicutreBox control has the SizeMode property which includes “CenterImage“.

I want my Image control to have that ability.

Is there anyway?

Thanks

My XAML code:

<Window x:Class="WpfApplication1.MainWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        Title="MainWindow" Height="768" Width="1024" xmlns:my="http://schemas.sharpsoft.net/xaml" xmlns:my1="clr-namespace:WpfApplication1">
    <Grid>
        <my1:CustomControl1
                    x:Name="customControl11"
                    Width="206"
                    Height="197"
                    HorizontalAlignment="Left"
                    VerticalAlignment="Top"
                    Margin="18,58,0,0"
                    Stretch="Uniform"/>
    </Grid>
</Window>

My CustomControl code:

public class CustomControl1 : Image
{
    public CustomControl1()
    {
        // Bitmap to Stream
        Stream ms = new MemoryStream();
        Properties.Resources.webcam_background.Save(ms, ImageFormat.Png);

        // Stream to BitmapImage
        BitmapImage bitmap = new BitmapImage();
        bitmap.BeginInit();
        bitmap.StreamSource = ms;
        bitmap.EndInit();

        // Set it
        Source = bitmap;
    }
}

Where “webcam_backgroud” is a png image added by default visual studio resource editor.

Set Stretch to None.

<Image Source="..." Stretch="None" />
