Multi Layer PDF

I have PDF with tons of layers. (can see it in Acrobat).
When open in Aspose Layers are null?
Is it possible to make this PDF “simpler” - ie - merge all layers to a single layer or something like this?

The file is: 1440-00-1- 500SCA.pdf on:
The number of layers can be seen here: Capture.PNG
Please see PDF on:



Thanks for contacting support.

We have tested the scenario with Aspose.Pdf for .NET 17.8 and observed that API was returning Layers count as zero. Please check following code snippet that we have tried to determine layers count from your PDF.

Document pdfDoc = new Document(dataDir + "Hagasha-part1SC.pdf");
foreach (Page page in pdfDoc.Pages)
 if (page.Layers != null)
