Hi Akilesh,

Thank you for contacting Syncfusion Support.

We attempted to reproduce the issue by loading the PDF in the PDF Viewer and saving it using the SaveDocumentAPI to a specified file path. However, we were unable to replicate the issue where “text markup annotations are not rendered correctly in the saved PDF.” In our saved PDF, the added text markup annotations appeared correctly in their expected positions. We have attached a sample, saved PDF and a video demonstrating the steps we followed during our testing.

Could you please review them and let us know if we missed any steps while attempting to reproduce the issue?

To help us investigate further, please provide the following details:

• The platform(s) where the issue occurs (e.g., Android, Windows, iOS, Mac Catalyst)
• Exact steps to reproduce the issue, if different from what we tested
• Device model and OS version, as the issue might be device-specific
• A modified sample, if available
• .NET MAUI package versions (e.g., Microsoft.Maui.Compatibility, Microsoft.Maui.Controls)
• Any other relevant information that might help us reproduce the issue

We appreciate your cooperation and look forward to your response.

Regards,
Bharathi S

Hi Bharathi,

I added some code for saving pdf and also added one pdf file.

When we are saving FlattenOnSave, first heading of the pdf is not working with text markups.

I attached modified zip solution. Please run and check.

Thanks

Akhilesh

Hi Akhilesh,

We have resolved the issue “Text markup annotations are not rendered correctly in the saved PDF when saved by flattening the annotations” and now the fix for the issue is available in our latest weekly NuGet 30.1.40.

Please find our latest Weekly NuGet:

https://www.nuget.org/packages/Syncfusion.Maui.PdfViewer/30.1.40

Root cause details:

The root cause of the issue is that, while flattening the annotation and saving it as a library annotation, the bounds were not applied. We have now applied the bounds to these annotation libraries before saving it.

Regards,
Bharathi S
