Here are some parts of the code :

In the Xaml file :


<inkcanvas grid.row="1" x:name="myInkcanvas0">
<Image x:Name="img0" Source="{Binding Path0}" />

<inkcanvas grid.row="1" x:name="myInkcanvas1">
<Image x:Name="img1" Source="{Binding Path1}"/>

<Button Content="Save" Click="Save"/>

In the main cs file :

private void Save(object sender, RoutedEventArgs e)
SaveFile(((DisplayViewModel)this.DataContext).Path0, myInkcanvas0);
SaveFile(((DisplayViewModel)this.DataContext).Path0, myInkcanvas1);

private void SaveFile(string sPath, InkCanvas cnv)
FileStream stream = new FileStream(sPath, FileMode.Open, FileAccess.ReadWrite);
RenderTargetBitmap rtb = new RenderTargetBitmap(1200, 300, 0, 0, PixelFormats.Default);

BmpBitmapEncoder encoder = new BmpBitmapEncoder();


--> Exception : the process can not access to the file myfile.png because it is used by another process.

Thank you for your reply. I want this verification takes place at the same time the plot. You think it will work?
Moreover squares are part of the Strokes, I can get the coordinates of each square of the Stroke?

I found the solution myself, I don't use two inkcanvas anymore because I can apply transformations directly on the image...
Thank you anyway.

I put an image that contains a green object on black background in an InkCanvas to be able to draw over. I also apply transformations to Inkvanvas (crushing, translation).

The fact of using a second InkCanvas allows me to draw in the departure area when the InkCanvas has been reduced and still have a black background behind.

I hope my explanation is not too confusing ...

thank you
