Hello again,
Ok I did some tests with the svg browser. In the view menu you have a "previous transform" and a "next transform" menu items.
So I did my test by choosing the "Transform..." menu item. I did a bunch of transforms and the next and previous menu item would never become enabled...
This did not work until I clicked on the Stop button that I noticed was enabled. Then all my transformations would trigger the gvtRenderingCompleted event and therefor update the transformHistory object...
Why is my SVG enabling the Stop button and others don`t because that seems to be my problem.
Thanks a lot,
Luc

In my tests it records all my pan and zoom actions. Are you including
the code from the JSVGViewerFrame that notifies the history class of
transform changes?

'canvas.getRenderingTransform()'.

'canvas.setRenderingTransform( affine );'
This is all in the JSVGViewerFrame class already. Just look for all
the lines with 'transformHistory'.
