Hi,
I am using LeadTools 17.5 with C#.Net. I have a raster file and i want to draw an AnnPointObject( with picture) as this will semi transparent so that my raster file and annotation will be visible and AnnPointObject(with picture) should be semi visible. my code is as follows:
/////////////////////////////////////////////////////////


CurvePolyLine CurvePolyLine = _view.PolyLineDrawDesigner.ObjectTemplate as CurvePolyLine;
                AnnPointObject fixPoint = new AnnPointObject();
                fixPoint.Name = "PointShift";
                fixPoint.NameVisible = false;
                fixPoint.Picture = new AnnPicture(global::TGSDig.Windows.FormsControl.Properties.Resources.Red_box_3px);
                List<AnnObject> annObjects = GetAllCurveDataFromPrepInfo(CurvePolyLine.SegmentNo, CurvePolyLine.TrackNo, CurvePolyLine.CurveIndex);
                fixPoint.CenterPoint = new AnnPoint(CurvePolyLine.PickedPoints[0].X, CurvePolyLine.PickedPoints[0].Y);
               (annObjects[0])).PickedPoints[0].X, ((CurvePolyLine)(annObjects[0])).PickedPoints[0].Y);

                _view.PrpAnnAutomation.Container.Objects.Add(fixPoint);

                _view.PrpAnnAutomation.Viewer.Invalidate();


////////////////////////////////////////////////
Thanks in advance

You can specify a specific color to be fully transparent by setting the AnnPicture.TransparentMode property to AnnPictureTransparentMode.UseColor and then set the AnnPicture.TransparentColor property to the color that you want.
For more information, please see this page:
http://www.leadtools.com/help/leadtools/v175/dh/wn/Leadtools.Windows.Annotations~Leadtools.Windows.Annotations.AnnPicture.html

About the semi transparent issue, there could be a workaround. Please send this issue to support@leadtools.com so that I can investigate more about this issue.

Thanks,
