resize - Showing only part of Canvas in WPF C# -

i have canvas in wpf project defined 1000 x 3000px.

now i'm using clip method point (0,1000) (1000, 2000). middle of canvas. want show in scrollviewer, there problem - have lot of space before , after clipped part. how align clipped canvas top?

more specific: canvas contain 3 pages (1000x1000px), want clip middle page , operate on it. in project want show 1 page @ top op scrollviewer. after clipping correct part of canvas, spaces before , after.

how it? maybe need use method instead of clip?

or maybe else? example split canvas after every 1000px.. in word :)

here's solution came with. have replace canvas yours.
