What does this mean?
I get this error with some pdf documents in the production environment. Other pdfs make no problem.
In our test environment the processing is correct with the same pdf causing problems in production!
What are possible causes?
The code snipplet:
fileStamp = new PdfFileStamp(inStream, outStream);
Stamp logoStamp = new Stamp();
logoStamp.BindLogo(new FormattedText(replacedText, new FontColor((byte)R, (byte)G, (byte)B), fontStyle, EncodingType.Winansi, true, (float)TextSize));
logoStamp.IsBackground = false;
logoStamp.PageNumber = i;
First off, please try to use the latest version at your end and see if it resolves your issue. However, if it still doesn’t resolve your issue then please share the input PDF file with us. Also, please share the details of the environment where it fails i.e. OS, .NET Framework version, application type (Web, Windows, Service etc.). We’ll investigate the issue at our end and guide you accordingly.
We’re sorry for the inconvenience.
I already tried the latest version...
As this is not the first problematic error (pages were mixed up in pdf concatenation), we decided to switch to PDFlib.
I’m very sorry for the inconvenience. Actually, if you could share the sample input file along with the details of your working environment, we would be able to investigate and provide a fix for this issue.
However, if you need any further assistance from our side, please do let us know.
