The below logic should help you update the bounding box . I am using quadpoints array and popupuating another array of x-cordinates and y-coordinates. After which bounding box is being updated with xmin,ymin and xmax,ymax.   Assuming annot is the object that you have shared....     var xcarray : Array<number> = []; var ycarray : Array<number> = []; var arrlength = event.data.target.selector.quadPoints.length; var qpoints = event.data.target.selector.quadPoints; for (var i =0 ; i< arrlength ; i++) { if (i % 2 ==0) { xcarray.push(qpoints[i]); } else { ycarray.push(qpoints[i]); } } var xmin = Math.min.apply(Math, xcarray); var ymin = Math.min.apply(Math, ycarray); var xmax = Math.max.apply(null,xcarray); var ymax = Math.max.apply(null,ycarray); annot.target.selector.boundingBox[0] = xmin; annot.target.selector.boundingBox[1] = ymin; annot.target.selector.boundingBox[2] = xmax; annot.target.selector.boundingBox[3] = ymax; annotationManager.updateAnnotation(annot);   Please see if this helps   Thanks Vasavi       ...

WIll I be able to downloadthe sdk files main.js/viewer.js and keep them locally and run the adobe embed Api.     Please let know how to go about this.   Thanks Vasavi ... View more

I was able to find a workaround for this issue.    First thing this is an itermittent issue.    code: 'FAIL', message: 'Annotation selector is not valid for given   we get the above error when the bounding box coordibates are incorrect. But the quad points have the right corrdinates. So the fix was to correct the bounding box coordinates based on the quad points. In my scenario I took the xmin, ymin and xmax,ymax from the quad points and updated the bouning box, Then the UpdateAnnotation api  started working perfectly!   Hope this helps ... View more

But I dont see the solution to this issue. Can you please let know the solution. Error: code: 'FAIL', message: 'Annotation selector is not valid for given   Not quite sure what is wrong with the selector, bounding box, quad points all seem to be correct. Comments alone am not able to update when I select lines partially using textselection as I get the above error. This is a bit of emergency and would highly appreciate your quick response.   Thanks Vasavi ... View more

We are experiencing the same problem while updating annotation comment. Any updates on this ? ... View more

this solution does not work on annotated text, works only on normal text selection.. any help to get the selected text from annotation ? ... View more
