Hi,

Try to set a new extent for the layer:

imgLayer.extent=new OpenLayers.Bounds(-70,-10,70,10);

This is perhaps needed to refresh the layer imgLayer.setVisibility(false); imgLayer.setVisibility(true);

Betreff: [OpenLayers-Users] how to change the size of OpenLayers.Layer.Image

Hi,

I am trying to use OL to view military images, jpeg, of various dimensions.
I need to maintain the orginal aspect. Now, how to specify the size values when creating a new Layer.Image?

Is it possible to change those values after image loads?

How?

Thanks.

JK
