Hi Philipp,
I actually get the same
effect when I try to transform the whole group by just scaling the <g>
tag.
When I go through the
list of child elements and scale one by one I don’t get the effect. But I
really think that scaling the group through the <g> tag would be more
efficient…

Betreff: Re: Some questions on the
JSVGScrollPane
Yes, they were both good suggestions. the next question is when I zoom
the canvas, the objects that i want to remain static are not affected by the
zooming but, they move, this is caused by the zooming of the canvas, but how
would I offset the movement of the items?

It should have moved when the canvas moved. It listens for
GvtRenderingCompleted events (fired when the rendering transform changes)
and recalculates it's scrollbar positions.

Steiner's answer on this is a pretty good one.
The other option is to put the zoomy bits in a group
or SVG element and adjust the transform on that group/svg
element rather than adjusting the canvas's rendering transform...
Of course you loose the JSVGScrollPane that way.
