Hi, I'm creating the DWG file using WW.CadLib and then using the sample code to export PDF from DWG file but generated PDF does not open.
I am sharing that DWG file and sample code. Please suggest.
public static void ExportToPdf(DxfModel model)
{
string filename = Path.GetFileName(model.Filename);
string dir = Path.GetDirectoryName(model.Filename);
string filenameNoExt = Path.GetFileNameWithoutExtension(filename);
// as PDF
using (FileStream stream = File.Create(Path.Combine(dir, filenameNoExt + ".pdf")))
{
PdfExporter pdfExporter = new PdfExporter(stream);
pdfExporter.EmbedFonts = true;
GraphicsConfig config = (GraphicsConfig)GraphicsConfig.WhiteBackgroundCorrectForBackColor.Clone();
config.DisplayLineTypeElementShapes = true;
config.TryDrawingTextAsText = true;
foreach (DxfLayout layout in model.OrderedLayouts)
{
if (layout.Name != "Model")
{
AddLayoutToPdfExporter(pdfExporter, config, model, null, layout);
}
}
pdfExporter.EndDocument();
}
}
