Post subject: | PDF document converted to grayscale when splitted |
Hello, I'm using some very basic code to split up a PDF document into multiple documents. For some reason, the resulting documents are saved in grayscale instead of color. Why could that be and how can I make sure it doesn't happen? The color should match the color of the original document, so if that contains color; the results should contain color as well. Code: public Stream[] SplitDocument(Stream fileStream, int[] splitOnPageNumbers)
{ PdfDocument inputDocument = PdfReader.Open(fileStream, PdfDocumentOpenMode.Import); List<Stream> result = new List<Stream>(); PdfDocument outputDocument = null; for (int page = 0; page < inputDocument.PageCount; page++) { // when there is no active document; create one if (outputDocument == null) { outputDocument = new PdfDocument(); outputDocument.Version = inputDocument.Version; outputDocument.Info.Title = inputDocument.Info.Title; outputDocument.Info.Creator = inputDocument.Info.Creator; } // add the page and save to stream outputDocument.AddPage(inputDocument.Pages[page]); // when this page was indicated as a split number; save the document // also save by default when it's the last page // add 1 to the page number because that's zero based, and the splitOnPageNumbers var is one based if (splitOnPageNumbers.Contains(page + 1) || page + 1 == inputDocument.PageCount) { Stream outputStream = new MemoryStream(); outputDocument.Save(outputStream, false); // don't close stream, it will be unusable result.Add(outputStream); outputDocument = null; // reset to null to spawn a new document } } return result.ToArray(); } |

Hi! datamex wrote: Why could that be and how can I make sure it doesn't happen? I don't know.The problem could be related to your PDF file. It would be good to have the PDF file and a working Visual Studio project to replicate the problem. |

Never mind, it's my own mistake. The document is processed by a couple of components actually and it's not PDFSharp causing this problem. Sorry to have bothered you! |
