@pipriles I assume you have your overlay coordinates in terms of image pixels? And you have a single image in your viewer? If so, you should be able to use viewer.viewport.imageToViewportCoordinates to convert to the viewport coordinates the plugin needs.
@altert Looks like the person with the rotation issue came up with a great solution: https://stackoverflow.com/questions/45456171/fabric-canvas-changing-position-when-openseadragon-image-is-rotated (thanks to @avandecreme's image rotation code)
