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(图像)的文档标题。
我在 使用 Open XML SDK 2.0 for Microsoft Office 生成带有页眉和页脚的文档在 Word 2007 中使用Microsoft 示例创建页眉和页脚,文本页眉工作得很好,但图像显示在页眉中损坏的图像图标、大小正确的边框和消息“此图像当前无法显示”。另外,我可以将所选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);
图像使用 LoadImage 方法加载,该方法源自 Microsoft 示例,但添加了宽度和高度参数,并返回一个绘图对象:
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;
}
使用它,以下代码可以工作,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);
以下代码无法将徽标图像放在标题中:
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;
}
我怀疑我做错了一些非常微妙的事情,因为我可以在除标题之外的任何地方加载图像。任何人都可以建议吗?
