Zoom in horizontally on draw2d canvas [message #503635]

Hi,

I have a view which is divided in 2 sections: draw2d canvas A and canvas
B. Both the canvas have a Scalable layered pane. I have implemented zoom
in - out functionality which works fine. Zoom in-out can be done by
using setScale() method of Scalable layered pane.
Problem description:
Canvas A is drawn in upper half of the view. Whereas canvas B lies in
lower half. Now for canvas A, when zoom in-out action is performed, I
would like the canvas to zoom in-out only widthwise. At present, using
the setScale method of Scalable layered pane causes the canvas to be
zoomed in-out both horizontally and vertically.

Is there a way we can zoom in-out only horizontally on a draw2d canvas A?
Can this be done on a scalable layered pane?

Any help/pointers are appreciated.

Thanks in advance,
Sneha
