Can you set a flag on a annotation by Javascript

[Tonny Vildevall]

Hi 

Using Webviewer, is there a way to set a flag on (e_no_zoom) on an annotation?

We want the user to pinpoint a part of the document by doubleclick and so far all i is well. Upon double click we create a new stamp annotation and adds it to the drawing but we dont know how to add this flag to the annotation.

Hi Tonny,

Currently the NoZoom flag exists on annotations in WebViewer but it isn't properly implemented for annotations other than the sticky note annotation.

To work around this for now you could add the following customizations to a config file.

var NoZoomSelectionModel = function(annotation, canModify, isSelected) {
    Annotations.BoxSelectionModel.call(this, annotation, canModify, isSelected);
};

NoZoomSelectionModel.prototype = {
    testSelection: function(annotation, x, y, zoom) {
        var width = annotation.Width;
        var height = annotation.Height;
        if (annotation.NoZoom) {
          width /= zoom;
          height /= zoom;
        }
        var right = annotation.X + width;
        var bottom = annotation.Y + height;
        return (x >= annotation.X && x <= right && y >= annotation.Y && y <= bottom);
    }
};
NoZoomSelectionModel.prototype = $.extend(true, new Annotations.BoxSelectionModel(), NoZoomSelectionModel.prototype);

var stampDraw = Annotations.StampAnnotation.prototype.draw;
Annotations.StampAnnotation.prototype.draw = function(ctx) {
    if (this.NoZoom) {
        ctx.translate(-this.X, -this.Y);
    }
    stampDraw.apply(this, arguments);
};
Annotations.StampAnnotation.prototype.selectionModel = NoZoomSelectionModel;

To set the NoZoom flag you just need to do myAnnot.NoZoom = true;
