Apryse SDK gives you the ability to create your own tools should you need one.

Creating a custom annotation tool in Xamarin.Android

Creating a new tool in Xamarin.Android is similar to creating a new tool in Android. See tutorial in Android guides.

For example, the equivalent of the example provided in the Android guide will be:

  1. Creating CustomTool:

C#

1using System;
2
3using pdftron.PDF;
4using pdftron.PDF.Tools;
5using pdftron.PDF.Tools.Utils;
6
7using Polygon = pdftronprivate.PDF.Annots.Polygon;
8
9namespace PDFNetAndroidXamarinSample
10{
11    public class CustomTool : RectCreate
12    {
13        public static ToolManager.IToolModeBase MODE = ToolManager.ToolMode.AddNewMode((int)Annot.Type.e_Polygon);
14
15        public CustomTool(PDFViewCtrl ctrl) : base(ctrl)
16        {
17
18        }
19
20        public override ToolManager.IToolModeBase ToolMode
21        {
22            get
23            {
24                return MODE;
25            }
26        }
27
28        protected override pdftronprivate.PDF.Annot CreateMarkup(pdftronprivate.PDF.PDFDoc doc, pdftronprivate.PDF.Rect bbox)
29        {
30            var poly = new Polygon(Polygon.Create(doc, (int)Annot.Type.e_Polygon, bbox));
31            var color = Utils.Color2ColorPt(Android.Graphics.Color.Red);
32            poly.SetColor(color, 3);
33            poly.SetVertex(0, new pdftronprivate.PDF.Point(bbox.X1, bbox.Y1));
34            poly.SetVertex(1, new pdftronprivate.PDF.Point(bbox.X1, bbox.Y2));
35            poly.SetVertex(2, new pdftronprivate.PDF.Point(bbox.X2, bbox.Y2));
36            poly.SetVertex(3, new pdftronprivate.PDF.Point(bbox.X2, bbox.Y1));
37            poly.IntentName = pdftronprivate.PDF.Annots.PolyLine.EPolygonCloud;
38            poly.BorderEffect = pdftronprivate.PDF.Annots.Markup.ECloudy;
39            poly.BorderEffectIntensity = 2.0;
40            poly.Rect = bbox;
41
42            return poly;
43        }
44    }
45}
  1. Using the tool:

C#

1mToolManager.Tool = new CustomTool(mPdfViewCtrl);
