6 years ago @apricea4 you can get annotation relative width and height as following:
annotation.shapes[0].geometry.width
annotation.shapes[0].geometry.heightThe values would be in range 0..1. To convert to pixels you can multiply the values by the image width and height, respectively.
Regarding anno.setProperties, it also breaks in my case, during the anno.makeAnnotatable call, saying:
TypeError: $annotator$$1$$.$setProperties$ is not a function:
annotorious.debug.js:2043:76
$JSCompiler_StaticMethods__initAnnotator$$

anno.setProperties breaks annotorious on the line anno.makeAnnotatable(viewer) in my code with the stack trace pointing to anno.min.js as well. I have tried putting it before and after the makeAnnotatable call. Has anyone successfully set the properties of an OpenSeadragon x annotorious annotation? I would like to be able to change the color and font of the text, change the color of the rectangle and make the annotations persist throughout the session.
Also, how might I get the height and width of an annotation in pixels? I see one can do annotation.text and so I imagine it would be annotation.height, but how can I guarantee pixels?
Thank you
