Aspose.Words For .NET是一種高級Word文檔處理API，用于執(zhí)行各種文檔管理和操作任務(wù)。API支持生成，修改，轉(zhuǎn)換，呈現(xiàn)和打印文檔，而無需在跨平臺(tái)應(yīng)用程序中直接使用Microsoft Word。此外，API支持所有流行的Word處理文件格式，并允許將Word文檔導(dǎo)出或轉(zhuǎn)換為固定布局文件格式和最常用的圖像/多媒體格式。

本文討論如何使用Aspose.Words以編程方式處理形狀。Aspose.Words中的形狀表示 繪圖層中的對象，例如AutoShape，文本框，自由格式，OLE對象，ActiveX控件或圖片。 Word文檔可以包含一個(gè)或多個(gè)不同的形狀。文檔的形狀由Shape類表示。

>>Aspose.Words for .NET已經(jīng)更新至v20.3，新增4大新功能，包括Xamarin不再需要單獨(dú)的DLL，F(xiàn)indReplaceOptions類擴(kuò)展了新屬性，實(shí)現(xiàn)了“ Letterlike”符號的正確呈現(xiàn)以及支持在文本框范圍內(nèi)動(dòng)態(tài)拉伸圖像，以及3鐘增強(qiáng)型功能，點(diǎn)擊下載體驗(yàn)

使用文檔生成器插入形狀

Document doc = new Document();
DocumentBuilder builder = new DocumentBuilder(doc);

//Free-floating shape insertion.
Shape shape = builder.InsertShape(ShapeType.TextBox, RelativeHorizontalPosition.Page, 100, RelativeVerticalPosition.Page, 100, 50, 50, WrapType.None);
shape.Rotation = 30.0;

builder.Writeln();

//Inline shape insertion.
shape = builder.InsertShape(ShapeType.TextBox, 50, 50);
shape.Rotation = 30.0;

OoxmlSaveOptions so = new OoxmlSaveOptions(SaveFormat.Docx);
// "Strict" or "Transitional" compliance allows to save shape as DML.
so.Compliance = OoxmlCompliance.Iso29500_2008_Transitional;

dataDir = dataDir + "Shape_InsertShapeUsingDocumentBuilder_out.docx";

// Save the document to disk.
doc.Save(dataDir, so);

設(shè)置寬高比鎖定

Document doc = new Document();
DocumentBuilder builder = new DocumentBuilder(doc);
var shape = builder.InsertImage(dataDir + "Test.png");
shape.AspectRatioLocked = false;

dataDir = dataDir + "Shape_AspectRatioLocked_out.doc";

// Save the document to disk.
doc.Save(dataDir);

在單元格中設(shè)置形狀布局

Document doc = new Document(dataDir + @"LayoutInCell.docx");
DocumentBuilder builder = new DocumentBuilder(doc);

Shape watermark = new Shape(doc, ShapeType.TextPlainText);
watermark.RelativeHorizontalPosition = RelativeHorizontalPosition.Page;
watermark.RelativeVerticalPosition = RelativeVerticalPosition.Page;
watermark.IsLayoutInCell = true; // Display the shape outside of table cell if it will be placed into a cell.

watermark.Width = 300;
watermark.Height = 70;
watermark.HorizontalAlignment = HorizontalAlignment.Center;
watermark.VerticalAlignment = VerticalAlignment.Center;

watermark.Rotation = -40;
watermark.Fill.Color = Color.Gray;
watermark.StrokeColor = Color.Gray;

watermark.TextPath.Text = "watermarkText";
watermark.TextPath.FontFamily = "Arial";

watermark.Name = string.Format("WaterMark_{0}", Guid.NewGuid());
watermark.WrapType = WrapType.None;

Run run = doc.GetChildNodes(NodeType.Run, true)[doc.GetChildNodes(NodeType.Run, true).Count - 1] as Run;

builder.MoveTo(run);
builder.InsertNode(watermark);
doc.CompatibilityOptions.OptimizeFor(MsWordVersion.Word2010);

dataDir = dataDir + "Shape_IsLayoutInCell_out.docx";

// Save the document to disk.
doc.Save(dataDir);

添加角落

Document doc = new Document();
DocumentBuilder builder = new DocumentBuilder(doc);
Shape shape = builder.InsertShape(ShapeType.TopCornersSnipped, 50, 50);

OoxmlSaveOptions so = new OoxmlSaveOptions(SaveFormat.Docx);
so.Compliance = OoxmlCompliance.Iso29500_2008_Transitional;
dataDir = dataDir + "AddCornersSnipped_out.docx";

//Save the document to disk.
doc.Save(dataDir, so);

獲取實(shí)際形狀邊界點(diǎn)

Document doc = new Document();
DocumentBuilder builder = new DocumentBuilder(doc);
var shape = builder.InsertImage(dataDir + "Test.png");
shape.AspectRatioLocked = false;

Console.Write("\nGets the actual bounds of the shape in points.");
Console.WriteLine(shape.GetShapeRenderer().BoundsInPoints);

指定垂直錨

Document doc = new Document(dataDir + @"VerticalAnchor.docx");
NodeCollection shapes = doc.GetChildNodes(NodeType.Shape, true);
Shape textBoxShape = shapes[0] as Shape;
if (textBoxShape != null)
{
    textBoxShape.TextBox.VerticalAnchor = TextBoxAnchor.Bottom;
}
doc.Save(dataDir + "VerticalAnchor_out.docx");

檢測SmartArt形狀

Document doc = new Document(dataDir + "input.docx");

int count = 0;
foreach (Shape shape in doc.GetChildNodes(NodeType.Shape, true))
{
    if (shape.HasSmartArt)
        count++;
}

Console.WriteLine("The document has {0} shapes with SmartArt.", count);

水平尺格式

Aspose.Words API提供Shape.HorizontalRuleFormat屬性，以訪問水平規(guī)則形狀的屬性。HorizontalRuleFormat類公開了用于設(shè)置水平尺的基本屬性，例如Height，Color，NoShade等。下面的代碼示例演示如何設(shè)置HorizontalRuleFormat。

DocumentBuilder builder = new DocumentBuilder();

Shape shape = builder.InsertHorizontalRule();
HorizontalRuleFormat horizontalRuleFormat = shape.HorizontalRuleFormat;

horizontalRuleFormat.Alignment = HorizontalRuleAlignment.Center;
horizontalRuleFormat.WidthPercent = 70;
horizontalRuleFormat.Height = 3;
horizontalRuleFormat.Color = Color.Blue;
horizontalRuleFormat.NoShade = true;

builder.Document.Save("HorizontalRuleFormat.docx");

插入OLE對象作為圖標(biāo)

Aspose.Words API提供了Shape.InsertOleObjectAsIcon函數(shù)，以將嵌入式或鏈接的OLE對象作為圖標(biāo)插入文檔。此功能允許指定圖標(biāo)文件和標(biāo)題。OLE對象類型應(yīng)使用文件擴(kuò)展名進(jìn)行檢測。下面的代碼示例演示如何將OLE對象作為Icon設(shè)置到文檔中。

Document doc = new Document();

DocumentBuilder builder = new DocumentBuilder(doc);
Shape shape = builder.InsertOleObjectAsIcon(dataDir + "embedded.xlsx", false, dataDir + "icon.ico", "My embedded file");

doc.Save(dataDir + "EmbeddeWithIcon_out.docx");

Console.WriteLine("The document has been saved with OLE Object as an Icon.");
