            header.push({
                type: 'actionButton',
                img: '<svg xmlns="http://www.w3.org/2000/svg" viewBox="0 0 24 24"><path d="m0 0h24v24h-24z" fill="none"></path><path d="m21 19v-14c0-1.1-.9-2-2-2h-14c-1.1 0-2 .9-2 2v14c0 1.1.9 2 2 2h14c1.1 0 2-.9 2-2zm-12.5-5.5 2.5 3.01 3.5-4.51 4.5 6h-14z"></path></svg>',
                onClick: function() {

                    var pages=docViewer.Pq.length;
                    onSavetwo();
                    async function onSavetwo() {

                        for (i = 1; i <= pages; i++) {
                            var stampAnnot = new Annotations.StampAnnotation();
                            stampAnnot.PageNumber = i;
                            stampAnnot.X = 100;
                            stampAnnot.Y = 250;
                            stampAnnot.Width = 275;
                            stampAnnot.Height = 40;
                            stampAnnot.ImageData = 'data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAB.....';
                            stampAnnot.Author = await annotManager.getCurrentUser();

                            annotManager.addAnnotation(stampAnnot);
                            annotManager.redrawAnnotation(stampAnnot);
                        }

                    }

                }
