Zooming only in one direction

Hello guys,

I am currently working on an java application where I
would need to zoom in and zoom out an SVG file, but
the twist is that I should perform zooming in just one
direction. Meaning, I should be able to perform
horizontal zooming, while keeping the vertical height
of the image constant.

I am using JSVG canvas to load my SVG file.


Thanks,


PhilipZ

   You can do this by using a non-uniform scale for the
renderingTransform.  There are many ways to adjust this
all the 'directly' provided means use uniform scale, but
most can be fairly easily modified to do a non-uniform
scale.

   In particular the JSVGCanvas.ZoomAction has a
constructor that takes separate x/y scales.  You
will have to replace the normal entries for zoom-in
out in the swing component of course.
