Question

我的OpenXML Word文档生成项目需要文本，表格和图像。但首先，我需要一个带有徽标（图片）的文档标题。

我使用Microsoft示例创建页眉和页脚 Generating Documents with Headers and Footers in Word 2007 by Using the Open XML SDK 2.0 for Microsoft Office，文字标题工作正常，但图片显示在标题中，包含损坏的图片图标，正确大小的边框，以及消息“此图片当前无法显示。 “此外，我可以将选定的图像加载到文档正文中。以下是我创建ImagePart的方法：

// Create AG logo part.
_agLogoPart = mainDocumentPart.AddImagePart(ImagePartType.Jpeg);
using (FileStream stream = new FileStream(_agLogoFilename, FileMode.Open))
{
    _agLogoPart.FeedData(stream);
}
_agLogoRel = mainDocumentPart.GetIdOfPart(_agLogoPart);

使用从Microsoft示例派生的LoadImage方法加载图像，但添加宽度和高度参数，并返回Drawing对象：

private static Drawing LoadImage(string relationshipId,
                             string filename,
                             string picturename,
                             double inWidth,
                             double inHeight)
{
double emuWidth = Konsts.EmusPerInch * inWidth;
double emuHeight = Konsts.EmusPerInch * inHeight;

var element = new Drawing(
    new DW.Inline(
    new DW.Extent { Cx = (Int64Value)emuWidth, Cy = (Int64Value)emuHeight },
    new DW.EffectExtent { LeftEdge = 0L, TopEdge = 0L, RightEdge = 0L, BottomEdge = 0L },
    new DW.DocProperties { Id = (UInt32Value)1U, Name = picturename },
    new DW.NonVisualGraphicFrameDrawingProperties(
    new A.GraphicFrameLocks { NoChangeAspect = true }),
    new A.Graphic(
    new A.GraphicData(
    new PIC.Picture(
    new PIC.NonVisualPictureProperties(
    new PIC.NonVisualDrawingProperties { Id = (UInt32Value)0U, Name = filename },
    new PIC.NonVisualPictureDrawingProperties()),
    new PIC.BlipFill(
    new A.Blip(
    new A.BlipExtensionList(
    new A.BlipExtension { Uri = "{28A0092B-C50C-407E-A947-70E740481C1C}" }))
    {
    Embed = relationshipId,
    CompressionState = A.BlipCompressionValues.Print },
    new A.Stretch(
    new A.FillRectangle())),
    new PIC.ShapeProperties(
    new A.Transform2D(
    new A.Offset { X = 0L, Y = 0L },
    new A.Extents { Cx = (Int64Value)emuWidth, Cy = (Int64Value)emuHeight }),
    new A.PresetGeometry(
    new A.AdjustValueList()) { Preset = A.ShapeTypeValues.Rectangle })))
    {
        Uri = "http://schemas.openxmlformats.org/drawingml/2006/picture"
    }))
    {
        DistanceFromTop = (UInt32Value)0U,
        DistanceFromBottom = (UInt32Value)0U,
        DistanceFromLeft = (UInt32Value)0U,
        DistanceFromRight = (UInt32Value)0U,
        EditId = "50D07946"
    });
return element;
}

使用此代码，以下代码可以正常工作，将图像加载到我想要的正文中的任何位置：

Paragraph paraImage = new Paragraph(new Run(LoadImage(_genomeImageRel, _genomeImageFilename, "name" + _genomeImageRel, 7.5, 2.925)));
body.AppendChild(paraImage);

以下代码无法在标题中添加徽标图片：

private static Header GeneratePageHeaderPart(string headerText)
{
    Header hdr = new Header(new Paragraph(new Run(LoadImage(_agLogoRel, _agLogoFilename, "name" + _agLogoRel, 2.57, 0.73))));
    return hdr;
}

我怀疑我做的事情非常微妙，因为我可以将图片加载到标题中的任何位置。有人可以建议吗？

我怀疑我做的事情非常微妙，因为我可以将图像加载到标题中的任何位置。

如果您能够将图像插入主文档，还可以使用此代码（private static Drawing LoadImage）在页眉或页脚中插入图像。

唯一的区别是您添加ImagePart 的地方：

要在文档的正文中插入图片，请向ImagePart添加MainDocumentPart：

_agLogoPart = mainDocumentPart.AddImagePart(ImagePartType.Jpeg);
...
 _agLogoRel = mainDocumentPart.GetIdOfPart(_agLogoPart);

要在标题中插入图片，您需要在用于创建标题的ImagePart中添加HeaderPart

_agLogoPart = headerPart.AddImagePart(ImagePartType.Jpeg);
...
_agLogoRel = headerPart.GetIdOfPart(_agLogoPart);

要在页脚中插入图片，您需要在用于创建页脚的ImagePart中添加FooterPart：

_agLogoPart = footerPart.AddImagePart(ImagePartType.Jpeg);
...
_agLogoRel = footerPart.GetIdOfPart(_agLogoPart);

请尝试以下代码：

Bitmap image = new Bitmap(imagePath);
SdtElement controlBlock = doc.MainDocumentPart.HeaderParts.First().Header.Descendants<SdtElement>().Where
                                (r => r.SdtProperties.GetFirstChild<Tag>().Val == tagName).SingleOrDefault();
 //find the Blip element of the content control
 Blip blip = controlBlock.Descendants<Blip>().FirstOrDefault();

 //add image and change embeded id
 ImagePart imagePart = doc.MainDocumentPart.AddImagePart(ImagePartType.Jpeg);
 using (MemoryStream stream = new MemoryStream())
 {
      image.Save(stream, ImageFormat.Jpeg);
      stream.Position = 0;
      imagePart.FeedData(stream);
 }
 blip.Embed = doc.MainDocumentPart.GetIdOfPart(imagePart);

private static MainDocumentPart AddHeader(MainDocumentPart mainDocPart)
        {
            string LogoFilename = System.Web.Hosting.HostingEnvironment.MapPath("~/Content/Images/TemplateLogo.png");     
            mainDocPart.DeleteParts(mainDocPart.HeaderParts);
            var FirstHeaderPart = mainDocPart.AddNewPart<HeaderPart>();
            var DefaultHeaderPart = mainDocPart.AddNewPart<HeaderPart>();
            var imgPartFirst = FirstHeaderPart.AddImagePart(ImagePartType.Jpeg);           
            var imagePartFirstID = FirstHeaderPart.GetIdOfPart(imgPartFirst);
            var imgPartDefault = FirstHeaderPart.AddImagePart(ImagePartType.Jpeg);
            var imagePartDefaultID = FirstHeaderPart.GetIdOfPart(imgPartDefault);
            using (FileStream fs = new FileStream(LogoFilename, FileMode.Open))
            {
                imgPartFirst.FeedData(fs);                
            }
            using (FileStream fsD = new FileStream(LogoFilename, FileMode.Open))
            {
                imgPartDefault.FeedData(fsD);
            }
            var rIdFirst = mainDocPart.GetIdOfPart(FirstHeaderPart);
            var FirstHeaderRef = new HeaderReference { Id = rIdFirst, Type = HeaderFooterValues.First };
            var rIdDefault = mainDocPart.GetIdOfPart(DefaultHeaderPart);
            var DefaultHeaderRef = new HeaderReference { Id = rIdDefault };

            var sectionProps = mainDocPart.Document.Body.Elements<SectionProperties>().LastOrDefault();
            if (sectionProps == null)
            {
                sectionProps = new SectionProperties();
                mainDocPart.Document.Body.Append(sectionProps);
            }
            sectionProps.RemoveAllChildren<HeaderReference>();        
            FirstHeaderPart.Header = GenerateFirstPicHeader(imagePartFirstID);
            DefaultHeaderPart.Header = GeneratePicHeader(imagePartDefaultID);
            FirstHeaderPart.Header.Save();
            DefaultHeaderPart.Header.Save();
            sectionProps.PrependChild(new TitlePage());

            sectionProps.AppendChild(DefaultHeaderRef);
            sectionProps.AppendChild(FirstHeaderRef);

            return mainDocPart;
        }
