我开始用c#做第一次绘图(jpg)。 我想将它直接插入word文档。
如果不将我的jpg保存到临时目录中,我可以这样做吗?
此时,我只能从临时目录加载图片:
public void InsertAPicture(string document, string fileName, string bookmarkName)
{
Paragraph newParag = null;
using (WordprocessingDocument wordprocessingDocument =
WordprocessingDocument.Open(document, true))
{
MainDocumentPart mainPart = wordprocessingDocument.MainDocumentPart;
ImagePart imagePart = mainPart.AddImagePart(ImagePartType.Jpeg);
using (FileStream stream = new FileStream(fileName, FileMode.Open))
{
imagePart.FeedData(stream);
}
newParag = AddImageToBody(wordprocessingDocument, mainPart.GetIdOfPart(imagePart));
replaceBookmarkText(wordprocessingDocument, bookmarkName, newParag);
}
}
private Paragraph AddImageToBody(WordprocessingDocument wordDoc, string relationshipId)
{
// Define the reference of the image.
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"
});
return new Paragraph(new Run(element));
}
private void replaceBookmarkText(WordprocessingDocument doc, string bookmarkName, Paragraph text)
{
var t = (from el in doc.MainDocumentPart.RootElement.Descendants<BookmarkStart>()
where (el.Name == bookmarkName) &&
(el.NextSibling<Run>() != null)
select el).First();
t.NextSibling<Run>().Append(text);
}
并且,我以这种方式创建了一个图形图像:
Bitmap objBitmap;
Graphics objGraphics;
//Create object
objBitmap = new Bitmap(200, 5);
objGraphics = Graphics.FromImage(objBitmap);
//Draw line
objGraphics.DrawLine(new Pen(Color.Red), 0, 0, 200, 200);
//Save
objBitmap.Save(Response.OutputStream, ImageFormat.Jpeg);
objGraphics.Dispose();
objBitmap.Dispose();
如何向我的InsertAPicture方法发送我的Graphics对象而不是我的图像路径文件?
答案 0 :(得分:1)
您应该将图片保存为MemoryStream
。然后将该流传递到InsertAPicture
以代替fileName
参数。然后阅读流而不是创建FileStream
