Can not load layered file

[mcap1234]

Hello,

I am using Spire.Office 7.11.0.
When i try to load .pdf file from stream, or even from file i get an error "Invalid/Unknown/Unsupported format".
I only get that error when i try to load that one file that has layers. Can send it privately if needed.

Code i use is:

Code: Select all

Spire.Pdf.PdfDocument pdfDocument = new PdfDocument();      
pdfDocument.LoadFromFile("pathToFile");


or

Code: Select all

Spire.Pdf.PdfDocument pdfDocument = new PdfDocument();      
pdfDocument.LoadFromBytes(byteArray);


Is there a workaround for this?

Best regards

Sorry, we still haven't reproduced the issue you mentioned. I noticed that your IDE doesn't seem to be Visual Studio 2022, we tested it on Visual Studio 2022.

Hello,

Thanks for your inquiry.
If version 7.12.4 has no issues, then the latest version 10.1.0 should also be fine. Currently, we are not entirely clear about the cause of your problem. If you need to upgrade to the latest version, please let us know the name of the IDE tool you are using, and we will investigate further.
