Openseadragon: Get image dimensions

Created on 24 Nov 2017  路  1Comment  路  Source: openseadragon/openseadragon

This may be very silly, but how can I get the image dimensions after having loaded an image? I need them to do some calculations on the svg overlays.

Assuming you just have a single image, it would be: 

viewer.world.getItemAt(0).getContentSize();

That gets you the actual pixel dimensions of the image, not its location in the viewport.
