Hi Didier,
Thank you for writing.
You can access the ImagePrimitive responsible for displaying it and set the
ScaleSize property to
a desired size. Please also note, that
ScaleSize property assumes that you have the
ImageScaling set to
SizeToFit:
I hope this helps. Should you have further questions please do not hesitate to write back.
Regards,
Hristo
