Export to PDF not showing correct background page information

Using Aspose.Diagram (24.9.0)

I’m trying to export .vsdx to .pdf using the code snippet in Convert Visio to PDF format|Documentation.

I’m encountering a problem with the export function: it’s not correctly processing the background data for each foreground page. All of my foreground pages share a common background page, which includes a border and text formulas designed to dynamically update specific text elements on each page. In the example I’ve provided, the “Tab Name” field should display “Uno,” “Dos,” and “Tres” for the corresponding pages. However, it is incorrectly showing “Border” for all the pages instead.

Also, the pdf export is including all background pages. Is it possible to have a trigger to include/exclude background pages? If we were to have it match the export file by Visio, it should be excluded by default.

I’ve attached my samples.
ExportByVisio.pdf is exported using the Visio app and it’s the result I wanted.
ExportByAspose.pdf is the pdf created using the code snippet sample.
Sample.vsdx is the Visio file I’m trying to export.

Thanks for the template file and output pdf.
Please try this sample code to set SaveForegroundPagesOnly to true before saving to pdf:

        Aspose.Diagram.Saving.PdfSaveOptions opts = new Aspose.Diagram.Saving.PdfSaveOptions();
        opts.SaveForegroundPagesOnly = true;
