Orientation problem

I am using version 17.1. I have an application that allows users to select pdf files and aspose combines them into a single pdf file. This works great and it even preserves the page orientation of the source files. The files open in acrobat reader and all the pages are displayed with their original orientations.

The problem is when you take one of the combined files and open it using the full version of Acrobat. The pages still look right but if you then add another pdf file to it - by dragging it into acrobat - the orientations get scrambled.

To summarize: Aspose works great if you just view the created files but the files produced do not behave properly if altered in Acrobat.

So is this a known bug? Is there a work around?

Hoping this is as simple as upgrading to the latest version of Aspose.

Well, we have combined two empty PDF documents with Aspose.Pdf for .NET 17.8, and then combined the resultant PDF with an empty PDF using Adobe Acrobat Pro XI. We could not replicate the problem of scrambled orientation of the final PDF in our environment.

This is the combined PDF with Aspose.Pdf API: ConcatenatePdfFiles_out.pdf (157.7 KB)
This is an empty PDF: EmptyPdf.pdf (79.4 KB)
This is the final combined PDF with Acrobat: ConcatenatePdfFiles_Adobe.pdf (86.7 KB)

Kindly download and try the latest version 17.8 of Aspose.Pdf for .NET API, and let us know how that goes into your environment.
