Plot to file error !

[TSYUK]

Hello! Everyone.

To plot to file, I'm customizing sample source code.

But, I can't set the value, config.IsPlotToFile = true;  because  plotInfo.ValidatedConfig is null.

I would be very appreciated if you could give me clue how to handle this issue.

Source code is as below.

public static void exPlotToFile()
{

         Document doc = Application.DocumentManager.MdiActiveDocument;
         Editor ed = doc.Editor;
         Database db = doc.Database;
         string currentFolder = Path.GetDirectoryName(doc.Name);
         using (Transaction tr = db.TransactionManager.StartTransaction())
         {
                // We'll be plotting the current layout
                BlockTableRecord currentSpace = (BlockTableRecord)tr.GetObject(db.CurrentSpaceId, OpenMode.ForRead);
                Layout layout = (Layout)tr.GetObject(currentSpace.LayoutId, OpenMode.ForRead);
                // PlotInfo object linked to the layout
                PlotInfo plotInfo = new PlotInfo();
                plotInfo.Layout = currentSpace.LayoutId;
                // Set the PlotSettings object based on the layout settings
                PlotSettings plotSettings = new PlotSettings(layout.ModelType);
                plotSettings.CopyFrom(layout);
                // The PlotSettingsValidator helps
               // create a valid PlotSettings object
                PlotSettingsValidator plotSettingsValidator = PlotSettingsValidator.Current;
                PlotConfigManager.RefreshList(RefreshCode.All);

               // scaled to fit
                plotSettingsValidator.SetPlotType(plotSettings, PlotType.Extents);
                plotSettingsValidator.SetUseStandardScale(plotSettings, true);
                plotSettingsValidator.SetStdScaleType(plotSettings, StdScaleType.ScaleToFit);
                plotSettingsValidator.SetPlotCentered(plotSettings, true);

                // Use standard DWF PC3, as
               // for today we're just plotting to file
                plotSettingsValidator.SetPlotConfigurationName(plotSettings, "DWF6 ePlot.pc3", "ISO A4 (297 x 210 MM)");
                plotSettingsValidator.SetCurrentStyleSheet(plotSettings, "Icad.ctb");

                plotInfo.OverrideSettings = plotSettings;
                PlotInfoValidator plotInfoValidator = new PlotInfoValidator();
                plotInfoValidator.MediaMatchingPolicy = MatchingPolicy.MatchEnabled;
                plotInfoValidator.Validate(plotInfo);

                 // A PlotEngine does the actual plotting
                // (can also create one for Preview)
               if (PlotFactory.ProcessPlotState == ProcessPlotState.NotPlotting)
               {
                        try
                        {

                                 PlotEngine plotEngine = PlotFactory.CreatePublishEngine();
                                 plotEngine.BeginPlot(null, null);

==> null Value      PlotConfig config = plotInfo.ValidatedConfig;
                                 config.IsPlotToFile = true;

                            plotEngine.BeginDocument(plotInfo, "TestPrint", null, 1, true, Path.Combine(currentFolder, "TestPrint" + plotInfo.ValidatedConfig.DefaultFileExtension));

                                 PlotPageInfo plotPageInfo = new PlotPageInfo();
                                 plotEngine.BeginPage(plotPageInfo, plotInfo, true, null);
                                 plotEngine.BeginGenerateGraphics(null);
                                 plotEngine.EndGenerateGraphics(null);
                                 plotEngine.EndPage(null);
                                 plotEngine.EndDocument(null);
                                 plotEngine.EndPlot(null);
                                 plotEngine.Destroy();
                                 plotEngine = null;
                      }
                      catch (System.Exception error) { System.Exception Err = error; }
                }

                else
                 {
                         ed.WriteMessage("\nAnother plot is in progress.");
                  }

         }

}
