Export to pdf

Hi

I'm using my own ShapeLibrary witch has images inside shapes. for example:

Code
Select All
<?xml version="1.0" encoding="utf-8"?>
<shapes xmlns="http://mindfusion.org/flowchart">
  <shape id="Start" fill-mode="Winding">
    <outline>
      <round-rectangle x="0" y="0" w="100" h="100" r="8" dash-style="Custom" width="-1" border="0"/>
    </outline>
    <decorations />
    <image x="0" y="0" width="100" height="100" src="..\..\images\Campaign\Element_Start.png" />
  </shape>
</shapes>


Everything is fine and I can drag an drop nodes from shapeListBox to diagramView and it works.
But when I export the diagram to pdf it doesn't export images and just shows empty nodes in pdf.

here is my export code:

Code
Select All
MindFusion.Diagramming.Export.PdfExporter pdf = new MindFusion.Diagramming.Export.PdfExporter();

string path = Server.MapPath(@"~\PDF\") + Session.SessionID + ".pdf";

pdf.Export(diagramView.Diagram, path);


I work in JavaApplet mode.
What's wrong in this senario? Thanks.

Does it work if you call ShapeLibrary.LoadFrom(shapelib_Path) before exporting?

It's been loaded by shapeLibrary component based on shapeLibraryLocation property and I don't load it manualy in code. It's been loaded successfully and I can work with the nodes without any problem. But the exporter component can't export it to Pdf.

Have you set ShapeLibraryLocation on the DiagramView, or only on the ShapeListBox? In the latter case the shapes might not be loaded automatically on the server side if you are using JavaApplet mode, and the control will replace the custom shapes with rectangles in the exported PDF. If there some shapes loaded indeed, could you check if their Shape.Image property is different from null?

Thank you for your reply.

I tested following code server-side:

MindFusion.Diagramming.Shape.FromId("Start")

It doesn't return null but the following code returns null:

MindFusion.Diagramming.Shape.FromId("Start").Image

It means the nodes are loaded successfully not images. What does it mean?!

It means the server could not find the images locally through the relative path, while the applet manages to build correct URL and download them successfully. It might have something to do with how the folders are mapped, or what's the current working folder when library is loaded.

Try copying the shapes file to the images folder and load it from there. Also leave just the file names in the xml, without any path.
