It would be cool if Klaus could add a zoom feature for scrollarea plugin, basic idea is to use scrollarea plugin for static maps or floorplans and to be able to zoomin and out !!!
Maibe you can try to scale the layer inside the scrollarea, and at the same time update the size of the scrollarea.
But until we don't have multires layer system I think it don't have many sense.. Hope it helps
Thanx jordi, but using scale method won't do it as hotspots are placed in absolute position.
Multires layer system isn't needed in most case as a png floorplan or jpg image map won't be that big, the idea is to display it 100% of the screen so you see it all in any device screen sizes, and then you can zoom into to display part of it fullsize.
So just make them in relative position, then you have it.
By the way, you said hotspots, you meant layers, isnt it ?
