We are concatenating pdf files using the PdfFileEditor.concatenate function. We have files that were converted from powerpoint via adobe professional and some converted via office 2007. The files that were converted via office 2007 display fine in the concatenated pdf, but the ones converted via adobe professional display partial landscape and partial portrait orientation. I have attached a copy of the original powerpoint file, the file converted via adobe pro, the file converted via office 2007, and the files concatenated via the concatenate function. The existing pdfs are added to the InputStream Array as ByteArrayInputStreams.
Our users upload files that we then convert so we cannot control how those files were converted and we need them all to display correctly when concatenated. The blank page at the front of the concatenated file is a pdf that we generate via Aspose Pdf.Java 2.7.0. I just had the code generate a blank page for purpoises of this sample.
I do not know the function that returns the Pdf.kit version or I would have supplied that too.
