绘制文字

在 Visio 中绘制文字

Aspose.Diagram for .NET API 允许开发人员在页面中绘制文本形状。下面的代码示例显示了如何在 Visio 绘图中绘制文本。

// For complete examples and data files, please go to https://github.com/aspose-diagram/Aspose.Diagram-for-.NET
// The path to the documents directory.
string dataDir = RunExamples.GetDataDir_VisioPages();
// Load diagram
Diagram diagram = new Diagram(dataDir + "Drawing1.vsdx");
//Initiazlie a new PointF[]
PointF[] ps = new PointF[] { new PointF(1, 2), new PointF(2, 0), new PointF(3, 2), new PointF(2, 4), new PointF(1, 2) };
//Draw a diamond shape in page
long shapeId = diagram.Pages[0].DrawPolyline(2, 2, 4, 4, ps);
// get the added shape from page
Shape shape = diagram.Pages[0].Shapes.GetShape(shapeId);
// add text to shape
shape.Text.Value.Add(new Txt("Hello world!"));
//Aspose.Diagram.Char ch = new Aspose.Diagram.Char();
//shape.Chars.Add(ch);
//ch.IX = 0;
//// set text font
//ch.FontName.Value = "Courier New";
//// set text color
//ch.Color.Value = "#ff0000";
//// set font size, unit is 72pt
//ch.Size.Value = 16 / 72.0;
//Aspose.Diagram.Para para = new Para();
//shape.Paras.Add(para);
//para.IX = 0;
//// set horizon align
//para.HorzAlign.Value = HorzAlignValue.LeftAlign;
//// set indent
//para.IndLeft.Value = 1.2;
// Save diagram
diagram.Save(dataDir + "AddTextToShape_out.vsdx", SaveFileFormat.VSDX);

在 SVG 中绘制文字

Aspose.Diagram for .NET API allows developers to draw a text in the page and save as SVG format. The code example below shows how to draw a text in a Visio drawing and save as SVG format.

// For complete examples and data files, please go to https://github.com/aspose-diagram/Aspose.Diagram-for-.NET
// The path to the documents directory.
string dataDir = RunExamples.GetDataDir_VisioPages();
// Load diagram
Diagram diagram = new Diagram(dataDir + "Drawing1.vsdx");
//Initiazlie a new PointF[]
PointF[] ps = new PointF[] { new PointF(1, 2), new PointF(2, 0), new PointF(3, 2), new PointF(2, 4), new PointF(1, 2) };
//Draw a diamond shape in page
long shapeId = diagram.Pages[0].DrawPolyline(2, 2, 4, 4, ps);
// get the added shape from page
Shape shape = diagram.Pages[0].Shapes.GetShape(shapeId);
// add text to shape
shape.Text.Value.Add(new Txt("Hello world!"));
//Aspose.Diagram.Char ch = new Aspose.Diagram.Char();
//shape.Chars.Add(ch);
//ch.IX = 0;
//// set text font
//ch.FontName.Value = "Courier New";
//// set text color
//ch.Color.Value = "#ff0000";
//// set font size, unit is 72pt
//ch.Size.Value = 16 / 72.0;
//Aspose.Diagram.Para para = new Para();
//shape.Paras.Add(para);
//para.IX = 0;
//// set horizon align
//para.HorzAlign.Value = HorzAlignValue.LeftAlign;
//// set indent
//para.IndLeft.Value = 1.2;
// Save diagram as SVG images
SVGSaveOptions imageSaveOptions = new SVGSaveOptions();
imageSaveOptions.PageIndex = 0;
diagram.Save(dataDir + "AddTextToShape_out.svg", imageSaveOptions);

在 PDF 中绘制文字

Aspose.Diagram for .NET API allows developers to draw a text in the page and save as PDF format. The code example below shows how to draw a text in a Visio drawing and save as PDF format.

// For complete examples and data files, please go to https://github.com/aspose-diagram/Aspose.Diagram-for-.NET
// The path to the documents directory.
string dataDir = RunExamples.GetDataDir_VisioPages();
// Load diagram
Diagram diagram = new Diagram(dataDir + "Drawing1.vsdx");
//Initiazlie a new PointF[]
PointF[] ps = new PointF[] { new PointF(1, 2), new PointF(2, 0), new PointF(3, 2), new PointF(2, 4), new PointF(1, 2) };
//Draw a diamond shape in page
long shapeId = diagram.Pages[0].DrawPolyline(2, 2, 4, 4, ps);
// get the added shape from page
Shape shape = diagram.Pages[0].Shapes.GetShape(shapeId);
// add text to shape
shape.Text.Value.Add(new Txt("Hello world!"));
//Aspose.Diagram.Char ch = new Aspose.Diagram.Char();
//shape.Chars.Add(ch);
//ch.IX = 0;
//// set text font
//ch.FontName.Value = "Courier New";
//// set text color
//ch.Color.Value = "#ff0000";
//// set font size, unit is 72pt
//ch.Size.Value = 16 / 72.0;
//Aspose.Diagram.Para para = new Para();
//shape.Paras.Add(para);
//para.IX = 0;
//// set horizon align
//para.HorzAlign.Value = HorzAlignValue.LeftAlign;
//// set indent
//para.IndLeft.Value = 1.2;
