Werken met connectors — Aspose.Slides FOSS voor .NET

Connectors zijn vormen die visueel twee andere vormen met een lijn verbinden. Aspose.Slides FOSS for .NET ondersteunt gebogen, rechte en kromme connectors. De aansluitpunten op een vorm worden geïdentificeerd door gehele getallen connection site indexes.

Verbindingssite-indexen

Elke vorm biedt vier standaard verbindingspunten:

IndexZijde
0Boven
1Links
2Onder
3Rechts

Een gebogen connector toevoegen tussen twee vormen 

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

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

Connectorvormtypen

ShapeTypeBeschrijving
ShapeType.BentConnector3Twee bochten van 90 graden (meest voorkomend voor diagrammen in stroomdiagramstijl)
ShapeType.BentConnector2Een bocht van 90 graden
ShapeType.BentConnector4Drie bochten van 90 graden
ShapeType.StraightConnector1Directe rechte lijn
ShapeType.CurvedConnector2Enkele vloeiende curve
ShapeType.CurvedConnector3Dubbele bocht curve

Top-naar-Beneden Verbinding 

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

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

Stroomschema met meerdere connectoren 

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)
{
    var conn = slide.Shapes.AddConnector(ShapeType.BentConnector3, 0, 0, 10, 10);
    conn.StartShapeConnectedTo = s1;
    conn.StartShapeConnectionSiteIndex = site1;
    conn.EndShapeConnectedTo = s2;
    conn.EndShapeConnectionSiteIndex = site2;
    return conn;
}

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

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)

prs.Save("flowchart.pptx", SaveFormat.Pptx);

Een connector opmaken

Connectoren ondersteunen dezelfde LineFormat eigenschappen als andere vormen:

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);
