  1. POOpenXML: Issue adding images to documents
    text
    copied!<p>Up until now, this block of code has been using to build documents with text for several months with no snags. I am now trying to dynamically add images. I've spent about two days staring at code and researching and am at an end. I suspect the issue is that relationships are not being created (more details below.) Maybe not?</p> <pre><code> //set stuff up... WordprocessingDocument doc = WordprocessingDocument.Open(fsPat, true, new OpenSettings(){ AutoSave = true, MarkupCompatibilityProcessSettings = new MarkupCompatibilityProcessSettings(MarkupCompatibilityProcessMode.ProcessAllParts, DocumentFormat.OpenXml.FileFormatVersions.Office2007), MaxCharactersInPart = long.MaxValue }); MainDocumentPart mainPart = doc.MainDocumentPart; . .Other stuff goes here . //now the fun... Run r2 = new Run(); // Add an ImagePart. ImagePart ip = mainPart.AddImagePart(ImagePartType.Png); string imageRelationshipID = mainPart.CreateRelationshipToPart(ip); // using (Stream imgStream = ip.GetStream()) { System.Drawing.Bitmap b = new System.Drawing.Bitmap("myfile.png"); b.Save(imgStream, System.Drawing.Imaging.ImageFormat.Png); } Drawing drawing = BuildImage(imageRelationshipID, "name"+imageRelationshipID.ToString(), 17, 17); r2.Append(drawing); p.Append(r2); </code></pre> <p>The image part is essentially copied from <a href="http://blog.stuartwhiteford.com/?p=33" rel="nofollow">http://blog.stuartwhiteford.com/?p=33</a>) and is running in a loop presently. I also copied his BuildImage() function and use it as-is.</p> <p>When I open the resulting docx, I see red Xs where the images are saying "This image cannot currently be displayed."</p> <p>When I open the zip, the images will appear in root/media, but not root/word/media as I'd expect. I also cannot find the images referenced in any of the relationship files. Ideally they'd be in root/word/_rels/document.xml.rels. You'll notice I changed how imageRelationshipID is set hoping to fix this. It didn't.</p> <p>Please help. Thank you.</p>
