Dear Sir/Madam,

I got ‘Request time out’ error when using export diagram to PDF.

My scenario is to use custom defined shapes for shapboxlist object, so user can drag and drop custom defined shape to diagramview and then have a button in web page to implement export PDF function.

In terms of shape, they are basic geometric shapes and you can see them in the attached file.

I am using PdfExporter to generate PDF file in NetDiagram. It runs perfectly. However when using more than 30 shapes on diagramview, it takes time to generate a pdf file and the pdf file size is slightly big please see this in http://s133.photobucket.com/albums/q77/jessary_chang/project/?action=view&curren....

In this case there are 76 shapes on diagram and the size of pdf is 9.34Mb, it takes around 7min 30secs to generate to pdf file.

So is there any option or setting that I can configure? Can you give me some suggestions?
Many thanks

Hello,

Thanks for your message; I didn’t use complicated texture for custom shape. I was drawing an outline first and fill color in the shape and then define text area, I didn’t use bitmap and more detail of object is below.

This is setting of DiagramView object

<ndiag:DiagramView ID="VSDiagramView" runat="server" Height="610px" Width="800px" NodeCreatedScript="onNodeCreated"
NodeDoubleClickedScript="onNodeDoubleClicked" ShapeLibraryLocation="../../LeanIcons.shl" BackColor="Transparent"
BorderColor="Transparent" LinkCreatedScript="onLinkCreated" JarLocation="../../JDiagram.jar">
<Diagram LinkHeadShape="PointerArrow" LinkBrush="s:#FFA9A9A9" LinkCrossings="Arcs" LinkHeadShapeSize="3"
LinkStyle="Bezier" BackBrush="s:#FFFFFFFF" />
</ndiag:DiagramView>




And export pdf’s code behind is below


Protected Sub ExportButton_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles ExportButton.Click
…………………

Dim pdf As MindFusion.Diagramming.Export.PdfExporter = _
New MindFusion.Diagramming.Export.PdfExporter()

Dim path As String = Server.MapPath("~/" & TempPDFDataRelatedPath) + Session.SessionID + ".pdf"
pdf.Export(VSDiagramView.Diagram, path)
pdfLink.NavigateUrl = "~/" + TempPDFDataRelatedPath + Session.SessionID + ".pdf"
pdfLink.Visible = True

……………………….
End Sub

Can I do some setting when calling PdfExporter?
Many thanks

Hi,

I am using NetDiagram version 3.1.1 in asp page, so I try to update it to V4, then let you know the result.

Many thanks

You can't control it at this time. We'll try to add support for arcs or use better approximation for the next release.
