From the Programmer's guide, we understand that by default the Bounds of a Diagram will be set to the standard A4 size, which is 210 mm X 297 mm. In WpfPoints this is 793.7 X 1122.51.

I am using the default MeasureUnit of WpfPoint.

In the Window_Loaded function, I set the value of the GridSizeX to 793.7 and that of GridSizeY to 1122.51 (boundaries of a A4). The expectation was the each cell in the grid will have a size of A4. The code was as follows,

digDSTEditor.ShowGrid = true;
digDSTEditor.GridStyle = MindFusion.Diagramming.Wpf.GridStyle.Lines;
digDSTEditor.GridSizeX = 793.7;
digDSTEditor.GridSizeY = 1122.51;
digDSTEditor.GridOffsetX = 0;
digDSTEditor.GridOffsetY = 0;
digDSTEditor.AlignToGrid = false;

Initially the grid lines were not shown because we had the page size equal to the grid cell size (so only one cell). So far so good

I created a node and dragged it towards right to the extent that a new cell was created and vertical grid line appeared. I left the node just next to the vertical grid line (a few millimeters away from it).

I exported this diagram to PDF (PageSize = A4, orientation = Portrait, AutoScale=false, AutoOrientation = false). I expected that the two pages would be created, which it did. The code for export was as follows,

MindFusion.Diagramming.Wpf.Export.PdfExporter exporter = new MindFusion.Diagramming.Wpf.Export.PdfExporter();
exporter.AutoOrientation = false;
exporter.AutoScale = MindFusion.Diagramming.Wpf.Export.AutoScale.None;
exporter.PageSize = MindFusion.Pdf.PageSize.A4;
exporter.PageOrientation = MindFusion.Pdf.PageOrientation.Portrait;
exporter.Margins.Top = 0;
exporter.Margins.Bottom = 0;
exporter.Margins.Right = 0;
exporter.Margins.Left = 0;

String path = @"c:\sampleExport.pdf";
exporter.Export(digDSTEditor, path);

However, the position of the node in the second page did not match the position of the node on the Diagram? In the Diagram, it was just a few millimeters away from the left, however, in the PDF it is far towards the right.

Am I doing something wrong or expecting something wrong?

I can send the screen shot of the diagram and also the PDF if required.

Thanks for the information. However, as you said it still does not work.

It will be great if the developer could provide us with clues so that we can complete our deliveries to the customer.

Thanks

Thanks for the new set of libraries.

It seems to be working fine for margins of 0. The page size as seen in the document properties also seems to be fine.

However, we definitely want to be able to leave a margin.

Also, I get label 'Trial version' on top left corner of canvas and hence in the exported PDF. Please let me know, what should I do (licenses upgrade etc) to get rid of 'Trial version' label?

Thanks,
Mukesh

This version should work also with margins > 0:
https://mindfusion.eu/_temp/wpfdiag_pdf.zip

Now margins are specified in WPF 96 DPI points, so you set half-inch margins in the PDF like this:

pdfex.Margins = new Thickness(48, 48, 48, 48);

and don't forget to subtract the margins sizes from the grid size.

I hope that helps,
