Lets say I have a canvas defined to be 1000x1000 big. Is it possible to only show a 100x100 part of it in a Viewbox(or a rectangel)?
Any help is apreciated.....
If you work with Brushes, you might want to take a look at Viewbox and Viewport in WPF
Edit: I just realised that Viewbox and Viewport are used for Brushes This is not really appropiate in your situation. I looked it up, and I think you will like the Clip property on UIElement.
Since Canvas is also a UIElement, you can use the Clip property to simulate a viewport on your Canvas..
Click here for some simple Geometry types
I think you would suffice with a RectangleGeometry
<Canvas>
<Canvas.Clip>
<RectangleGeometry Rect="50,50,25,25" />
</Canvas.Clip>
</Canvas>
Edit #2:
Hehe ok.. if you want your total Canvas displayed, only smaller, perheps you should take a look and LayoutTransform. Then use a ScaleTranform to resize your Canvas ;).
<Canvas>
<Canvas.LayoutTransform>
<ScaleTransform CenterX="0" CenterY="0" ScaleX="0.5" ScaleY="0.5" />
</Canvas.LayoutTransform>
</Canvas>
Tweak the parameters until you receive the desired effect ;)
