Add point to Polygon SOLVED

[jthomas]

I have tried adding points to the Vertices list of a polygon annotation but have not had any success with the Insert functions. When the code executes, the count of Vertices stays the same. Why are the insert functions not adding the point?

Code: Select all

    if (sortedDistances.Count > 2)
    {
        PXC_PointF pdfPointF = new PXC_PointF()
        {
            x = Convert.ToSingle(pdfPoint.x),
            y = Convert.ToSingle(pdfPoint.y)
        };
        int p1Index = sortedDistances[ 0 ].Index;
        int p2Index = sortedDistances[ 1 ].Index;
        uint minIndex = Convert.ToUInt32(Math.Min(p1Index, p2Index));
                                
        polygonData.Vertices.Insert(pdfPointF, 1, minIndex);
        polygonData.Vertices.Insert(polygonData.Vertices.get_Item(0));
        viewer.UpdateAnnotation(annot, polygonData);
    }

To clarify, polygonData is of type IPXC_AnnotData_Poly.

Hello Jared,

Have you tried using this operation:

Hi Alex,

The 'annot.setData' operation is being called in the viewer.UpdateAnnotation function.

How do I add a point to IPXC_PolygonSrcF object? The insert function has not worked for me.

Here is a link to the 'viewer.UpdateAnnotation Function'

Hello Jared,

Well, here's the case where the C# itself is the case why the code is not working. Try this:

Code: Select all

IPXC_AnnotData_Poly_Vertices vert = polygonData.Vertices;
vert.Insert(pdfPointF, 1, minIndex);
vert.Insert(polygonData.Vertices.get_Item(0));
polygonData.Vertices = vert;
viewer.UpdateAnnotation(annot, polygonData);

Cheers,
Alex

Hi Alex,

I tried the method listed above. The point was added to the list but it was not drawn to the UI.

I have found an alternative solution through JS.

Code: Select all

uint minIndex = Convert.ToUInt32(closestAnnotIndex);

string command = "var a = this.getAnnot(" +
    (closestAnnot.PageIndex) + ", \"" + closestAnnot.Name +
    "\"),verts = a.vertices; verts.splice(" +
    (minIndex + 1) + ", 0,[" + pdfPointF.x + "," + pdfPointF.y +
    "]),a.vertices = verts;";
PDFXEdit.IString res = viewer.IPxv.CreateString();
try
{
    viewer.PdfCtrl.Inst.ExecuteJS(viewer.PdfCtrl.Doc, command, PDFXEdit.PXV_ActionTriggerClass.PAEC_External, PDFXEdit.PXV_ActionTriggerSubclass.PAESC_Exec, null, res);
}
catch { }

Thanks,

Jared
