You can load the image on a temporary RasterImage object, then use the RasterImage.Paint Method in the RasterImageViewer to set the desired display rectangle of the image.

Thanks for your answer but do you have another way to make it? Because I have to show this RasterImage many times during the process and with your solution , this RasterImage use a lot of memory.

I can't think of a different way.
However, the memory usage is the same. In my approach, you load the image into an external RasterImage object.
The 'normal' way of displaying an image is load the image into RasterImageViewer.Image instead.

In both cases, you will be holding only one copy of the full bitmap in memory.
What do you mean that the RasterImage uses a lot of memory?
