using DocumentFormat.OpenXml; using DocumentFormat.OpenXml.Packaging; using DocumentFormat.OpenXml.Wordprocessing; using A = DocumentFormat.OpenXml.Drawing; using DW = DocumentFormat.OpenXml.Drawing.Wordprocessing; // Assuming you have an array of image byte arrays byte[][] imageByteArrays = GetImageByteArraysFromDatabase(); using (WordprocessingDocument document = WordprocessingDocument.Create("Output.docx", WordprocessingDocumentType.Document)) { // Create the main document part MainDocumentPart mainPart = document.AddMainDocumentPart(); mainPart.Document = new Document(); // Create a body for the document Body body = mainPart.Document.AppendChild(new Body()); // Loop through each image byte array foreach (byte[] imageBytes in imageByteArrays) { // Create an image part and add it to the main document part ImagePart imagePart = mainPart.AddImagePart(ImagePartType.Jpeg); using (System.IO.MemoryStream stream = new System.IO.MemoryStream(imageBytes)) { imagePart.FeedData(stream); } // Create a unique relationship ID for the image string relationshipId = mainPart.GetIdOfPart(imagePart); // Create a new paragraph and run for the image Paragraph paragraph = body.AppendChild(new Paragraph()); Run run = paragraph.AppendChild(new Run()); // Create a drawing and add it to the run Drawing drawing = run.AppendChild(new Drawing()); DW.Inline inline = drawing.AppendChild(new DW.Inline()); // Create a graphic and add it to the inline A.Graphic graphic = inline.AppendChild(new A.Graphic()); graphic.GraphicData = new A.GraphicData(new A.Picture(new A.BlipFill(new A.Blip() { Embed = relationshipId }), new A.Stretch(new A.FillRectangle()))); // Set the size of the image inline.Extent = new A.Extent() { Cx = 500000, Cy = 500000 }; // Adjust the size as needed // Save the document document.Save(); } }

To convert image byte arrays into a .docx file using Open XML, you can follow these steps: Create a new Word document using the Open XML SDK. Insert the images into the document. Save the document as a .docx file.

An option that can be used is to leverage the DocumentConverter class which would allow you to pass the byte data from the database, convert it to a stream, and then output a .docx file. Here is some code that demonstrates this: static void Main(string[] args) { var outBytes = ConvertStreams(new MemoryStream(inBytes)); // supply your byte data here File.WriteAllBytes("C:\Output\file.docx", outBytes.ToArray()); } static MemoryStream ConvertStreams(Stream inputStream) { var ms = new MemoryStream(); //output stream using var document = DocumentFactory.LoadFromStream(inputStream, new LoadDocumentOptions()); using var documentConverter = new DocumentConverter(); var jobData = new DocumentConverterJobData { Document = document, DocumentFormat = DocumentFormat.Docx, OutputDocumentStream = ms }; var job = documentConverter.Jobs.CreateJob(jobData); documentConverter.Jobs.RunJob(job); if (job.Status == DocumentConverterJobStatus.Success) return ms; else return null; } https://www.leadtools.com/help/sdk/tutorials/dotnet-console-convert-files-with-the-document-converter.html

Hi, I would suggest you could try free spire.doc to process Word documents. Here is the code snippet for your reference. using Spire.Doc; using System.Drawing; using Spire.Doc.Documents; using Spire.Doc.Fields; namespace InsertPicToDoc { class Program { static void Main( string [] args) { //Create a Word document Document document = new Document(); //Add a section Section section = document.AddSection(); //Add a paragraph Paragraph p = section.AddParagraph(); //Load an image from stream Image img = Image.FromStream(btyeImge); //Append the image to paragraph DocPicture Pic = p.AppendPicture(img); //Set the image size Pic.Width = 750; Pic.Height = 468; //Save the document document.SaveToFile( "InsertImage.docx" , FileFormat.Docx); } } }
