要使用 Open XML SDK 2.5 将图像添加到/word/media
文件夹,您必须自己为图像创建包部分。该类的AddImagePart()
成员函数MainDocumentPart
始终将图像存储在/media
文件夹中。
/word/media
下面的代码显示了如何使用以下步骤将图像插入文件夹:
- 创建一个
PackagePart
路径 Uri 设置为/word/media
.
- 将图像数据输入包部分。
- 为图像创建一个
PackageReleationship
。
- 使用 的 ID
PackageReleationship
来引用 word 文档中的图像。
我已经从这个MSDN网站复制了AddImageToBody()
函数的代码。
static void Main(string[] args)
{
InsertAPicture("mydoc.docx", "mypic.jpg");
}
public static void InsertAPicture(string document, string fileName)
{
using (WordprocessingDocument wordprocessingDocument =
WordprocessingDocument.Open(document, true))
{
MainDocumentPart mainPart = wordprocessingDocument.MainDocumentPart;
Uri imageUri = new Uri("/word/media/" +
System.IO.Path.GetFileName(fileName), UriKind.Relative);
// Create "image" part in /word/media
// Change content type for other image types.
PackagePart packageImagePart =
wordprocessingDocument.Package.CreatePart(imageUri, "Image/jpeg");
// Feed data.
byte[] imageBytes = File.ReadAllBytes(fileName);
packageImagePart.GetStream().Write(imageBytes, 0, imageBytes.Length);
PackagePart documentPackagePart =
mainPart.OpenXmlPackage.Package.GetPart(new Uri("/word/document.xml", UriKind.Relative));
Console.Out.WriteLine(documentPackagePart.Uri);
// URI to the image is relative to releationship document.
PackageRelationship imageReleationshipPart = documentPackagePart.CreateRelationship(
new Uri("media/" + System.IO.Path.GetFileName(fileName), UriKind.Relative),
TargetMode.Internal, "http://schemas.openxmlformats.org/officeDocument/2006/relationships/image");
AddImageToBody(wordprocessingDocument, imageReleationshipPart.Id);
}
}
private static void AddImageToBody(WordprocessingDocument wordDoc, string relationshipId)
{
var element =
new Drawing(
new DW.Inline(
new DW.Extent() { Cx = 990000L, Cy = 792000L },
new DW.EffectExtent()
{
LeftEdge = 0L,
TopEdge = 0L,
RightEdge = 0L,
BottomEdge = 0L
},
new DW.DocProperties()
{
Id = (UInt32Value)1U,
Name = "Picture 1"
},
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 = "New Bitmap Image.jpg"
},
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 = 990000L, Cy = 792000L }),
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"
});
wordDoc.MainDocumentPart.Document.Body.AppendChild(
new DocumentFormat.OpenXml.Wordprocessing.Paragraph(
new DocumentFormat.OpenXml.Wordprocessing.Run(element)));
}
当然,如果您想添加其他图像类型(例如 PNG),您必须更改内容类型。
