Creating annotations with a single click

[Matt Parizeau]

Q:

I want to create an annotation of a fixed size with a single click instead of requiring a click/drag to set the width and height. Is this possible?

A:

The following code is based on the custom diamond sample and should be able to be adjusted for other types of annotations, including custom ones.

var CustomDiamondCreateTool = function(docViewer) {

    Tools.GenericAnnotationCreateTool.call(this, docViewer, CustomDiamondAnnotation);

};

CustomDiamondCreateTool.prototype = new Tools.GenericAnnotationCreateTool();

CustomDiamondCreateTool.prototype.mouseLeftDown = function() {

    Tools.AnnotationSelectTool.prototype.mouseLeftDown.apply(this, arguments);

};

CustomDiamondCreateTool.prototype.mouseMove = function() {

    Tools.AnnotationSelectTool.prototype.mouseMove.apply(this, arguments);

};

CustomDiamondCreateTool.prototype.mouseLeftUp = function(e) {

    var annotation;

    Tools.GenericAnnotationCreateTool.prototype.mouseLeftDown.call(this, e);

    if (this.annotation) {

        this.annotation.Width = 100;

        this.annotation.Height = 100;

        annotation = this.annotation;

    }

    Tools.GenericAnnotationCreateTool.prototype.mouseLeftUp.call(this, e);

    if (annotation) {

        readerControl.docViewer.getAnnotationManager().redrawAnnotation(annotation);

    }

};
