Text zeichnen

Zeichnen Sie Text in Visio

Aspose.Diagram for .NET API ermöglicht es Entwicklern, eine Textform auf einer Seite zu zeichnen. Das folgende Codebeispiel zeigt, wie ein Text in einer Visio-Zeichnung gezeichnet wird.

// 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);

Zeichnen Sie Text in SVG

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);

//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();
