Multiple Pages with Dynamic Content- Content is Hidden When Concatenated Using PdfFileEditor.Concatenate

When concatenating multiple documents with dynamically generated content fields the resulting document is not displaying but is displaying in the preview when you scroll through the document. The last document does display it content correctly.

I have attached a .NET project to illustrate the issue and attached a screenshot of what the preview looks like.

The content shows when you click and drag the scroll bar on the right through the pdf document.

this has been tested with and w/o using our license. We have also tested this with streams and documents written to disk with the same result.

var slides = new List();

//// this is simulating returning pdfs from aws s3
for (var i = 1; i <= 23; i++)
slides.Add(new WorkingPdf { Url = string.Format("{0}.pdf", i.ToString(“000”)), InputStream = EmbededResources.GetEmbeddedFile(“FMG.AsposePdfDemo”, “FMG.AsposePdfDemo.EmbeddedResources.001.pdf”, false).ToMemoryStream() });

//// image would be coming from AWS S3 storage
using (var logoImage = EmbededResources.GetEmbeddedFile(“FMG.AsposePdfDemo”, “FMG.AsposePdfDemo.EmbeddedResources.logo.png”, false).ToMemoryStream())
//// fields are generated from the database
using (var xmlFields = EmbededResources.GetEmbeddedFile(“FMG.AsposePdfDemo”, “FMG.AsposePdfDemo.EmbeddedResources.fields.xml”, false).ToMemoryStream())
xmlFields.Seek(0, SeekOrigin.Begin);

//// image is being saved to disk due to issue: PDFKITNET-27777
DirectoryInfo tempDirectoryInfo;
var tempFileName = WriteImageToDiskGetTempFileName(logoImage, out tempDirectoryInfo);

//// Add content to pdfs
slides.ForEach(slide => ImportPdfContent(xmlFields, slide, tempFileName));

//// write pdf to disk so we can inspect the files have been updated correctly
//// pdf documents ar output to the project bin directory

//// concatenate the slides to a single document
var editor = new PdfFileEditor();
editor.Concatenate(slides.Select(slide => slide.Url).ToArray(), “result.pdf”); //// result pdf document outputs to the project bin directory


slides.ForEach(slide => { slide.InputStream.Close(); slide.InputStream.Dispose(); });
slides.ForEach(slide => { slide.OutputStream.Close(); slide.OutputStream.Dispose(); });
