Connectors

Treballant amb connectors — Aspose.Slides FOSS per a .NET

Els connectors són formes que enllacen visualment dues altres formes amb una línia. Aspose.Slides FOSS per a .NET admet connectors corbats, rectes i curvats. Els punts de connexió d’una forma s’identifiquen per un enter índexs de llocs de connexió.

Índexs de punts de connexió

Cada forma exposa quatre punts de connexió estàndard:

0Superior
1Esquerra
2Inferior
3Dreta

Afegint un connector doble entre dues formes 

using Aspose.Slides.Foss;
using Aspose.Slides.Foss.Export;

using var prs = new Presentation();
var slide = prs.Slides[0];

// Create two shapes to connect
var box1 = slide.Shapes.AddAutoShape(ShapeType.Rectangle, 50, 150, 150, 60);
box1.AddTextFrame("Start");

var box2 = slide.Shapes.AddAutoShape(ShapeType.Rectangle, 400, 150, 150, 60);
box2.AddTextFrame("End");

// Add a bent connector (position/size are ignored once connected)
var conn = slide.Shapes.AddConnector(ShapeType.BentConnector3, 0, 0, 10, 10);

// Connect right side of box1 to left side of box2
conn.StartShapeConnectedTo = box1;
conn.StartShapeConnectionSiteIndex = 3;   // right
conn.EndShapeConnectedTo = box2;
conn.EndShapeConnectionSiteIndex = 1;     // left

Tipus de formes de connector

ShapeTypeDescripció
ShapeType.BentConnector3Dos girs de 90 graus (el més comú per a diagrames d’estil fluxograma)
ShapeType.BentConnector2Un gir de 90 graus
ShapeType.BentConnector4Tres girs de 90 graus
ShapeType.StraightConnector1Línia recta directa
ShapeType.CurvedConnector2Corba suau única
ShapeType.CurvedConnector3Corba de doble gir

using Aspose.Slides.Foss;
using Aspose.Slides.Foss.Export;

using var prs = new Presentation();
var slide = prs.Slides[0];

var top = slide.Shapes.AddAutoShape(ShapeType.Rectangle, 250, 80, 200, 60);
top.AddTextFrame("Decision");

var bottom = slide.Shapes.AddAutoShape(ShapeType.Rectangle, 250, 300, 200, 60);
bottom.AddTextFrame("Action");

var conn = slide.Shapes.AddConnector(ShapeType.BentConnector3, 0, 0, 10, 10);
conn.StartShapeConnectedTo = top;
conn.StartShapeConnectionSiteIndex = 2;    // bottom of top box
conn.EndShapeConnectedTo = bottom;
conn.EndShapeConnectionSiteIndex = 0;      // top of bottom box

Diagrama de flux amb múltiples connectors 

using Aspose.Slides.Foss;
using Aspose.Slides.Foss.Export;

static IAutoShape AddBox(ISlide slide, string text, float x, float y,
    float w = 160, float h = 50)
{
    var s = slide.Shapes.AddAutoShape(ShapeType.Rectangle, x, y, w, h);
    s.AddTextFrame(text);
    return s;
}

static IConnector Connect(ISlide slide, IShape s1, int site1, IShape s2, int site2)

using var prs = new Presentation();

var start = AddBox(slide, "Start", 260, 60);
var process = AddBox(slide, "Process Data", 260, 180);
var end = AddBox(slide, "End", 260, 300);

Connect(slide, start, 2, process, 0);    // start -> process (bottom to top)
Connect(slide, process, 2, end, 0);      // process -> end (bottom to top)

Formatar un connector

Els connectors admeten el mateix LineFormat propietats com les altres formes:

using Aspose.Slides.Foss;
using Aspose.Slides.Foss.Drawing;
using Aspose.Slides.Foss.Export;

using var prs = new Presentation();
var slide = prs.Slides[0];
var box1 = slide.Shapes.AddAutoShape(ShapeType.Rectangle, 50, 150, 150, 60);
var box2 = slide.Shapes.AddAutoShape(ShapeType.Rectangle, 400, 150, 150, 60);

var conn = slide.Shapes.AddConnector(ShapeType.BentConnector3, 0, 0, 10, 10);
conn.StartShapeConnectedTo = box1;
conn.StartShapeConnectionSiteIndex = 3;
conn.EndShapeConnectedTo = box2;
conn.EndShapeConnectionSiteIndex = 1;

// Style the connector line
conn.LineFormat.Width = 2.5;
conn.LineFormat.DashStyle = LineDashStyle.Dash;
conn.LineFormat.FillFormat.SolidFillColor.Color = Color.DarkBlue;

prs.Save("styled-connector.pptx", SaveFormat.Pptx);
