The pdf generated by you is correct, my PDF version is 10.1.10

I am using following code to draw links.

sStartNodeID = htIDWithStatementNumber[alIFstartNode[iCounter].ToString()].ToString();
                sEndNodeID = htIDWithStatementNumber[alIFEndNode[iCounter].ToString()].ToString();
                ShapeNode SourceNode = DiagramView1.Diagram.FindNodeById(sStartNodeID) as ShapeNode;
                ShapeNode DestNode = DiagramView1.Diagram.FindNodeById(sEndNodeID) as ShapeNode;
                DiagramLink d1 = factory.CreateDiagramLink(SourceNode, DestNode);
                d1.Text = "NO";
                d1.HeadShape = ArrowHeads.Triangle;
                d1.HeadBrush = new MindFusion.Drawing.SolidBrush(System.Drawing.Color.Black);

Please attach your PDF exported from same diagram for our developer to investigate the differences. What OS, IIS, .NET CLR and NetDiagram versions are you using? Also are you doing any additional processing on the exported file, like appending pages using a third-party PDF library?

What does this code show in the Visual Studio console if you call it just before exporting the diagram?

Code
Select All
var measureBmp = new Bitmap(32, 32);
var measureGraphics = Graphics.FromImage(measureBmp);
measureGraphics.PageUnit = GraphicsUnit.Millimeter;
var size = measureGraphics.MeasureString(
	"Yes :Next Iteration", diagram.Font);
Debug.WriteLine(size);

Nevermind, we managed to reproduce that. Call this to reset some cached text layout information of links before exporting and the texts should look ok:

Code
Select All
foreach (var link in diagram.Links)
{
	link.TextStyle = LinkTextStyle.Follow;
	link.TextStyle = LinkTextStyle.Center;
}
PdfExporter ...


We'll release a fix next week.

I hope that helps,
Stoyan

The version here will export link texts at correct locations without having to reset their layout:

If you are generating it manually via the XML API, you must also add <resources><brushes .../>... section to the file in order to load values such as <HeadBrush Id="31" />. Better create it through a Diagram instance and call its SaveToXml method to make sure there's nothing missing.

I have following data, is it enough?

Node ID, shape, color.
for Link -- source ID and target ID.

just I want to draw diagram using XML.

Please send appropriate format of XML for above data.

The ID attribute in a Node/Brush element must have a corresponding Resources/Brushes/Brush definition with same Index attribute, e.g.:

Code
Select All
<Brushes>
      <Brush Index="31" Type="Solid">
        <Color>#FF7CFC00</Color>
      </Brush>
      ...


You can skip the Brush element in node to use default colors.

You can load diagram objects from arbitrary XML format using code as in this tutorial:

I don't want to use arbitrary XML format again, Just tell me Is it possible to load XML directly?

I guess Yes, right then tell me proper format of XML so that I can build XML in that format and can load directly.
