Werken met connectors — Aspose.Slides FOSS voor Java

Connectors zijn vormen die visueel twee andere vormen met een lijn verbinden. Aspose.Slides FOSS for Java 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:

Een gebogen connector toevoegen tussen twee vormen 

import org.aspose.slides.foss.Presentation;
import org.aspose.slides.foss.ShapeType;
import org.aspose.slides.foss.export.SaveFormat;

try (Presentation prs = new Presentation()) {
    var slide = prs.getSlides().get(0);

    // Create two shapes to connect
    var box1 = slide.getShapes().addAutoShape(ShapeType.RECTANGLE, 50, 150, 150, 60);
    box1.addTextFrame("Start");

    var box2 = slide.getShapes().addAutoShape(ShapeType.RECTANGLE, 400, 150, 150, 60);
    box2.addTextFrame("End");

    // Add a bent connector (position/size are ignored once connected)
    var conn = slide.getShapes().addConnector(ShapeType.BENT_CONNECTOR3, 0, 0, 10, 10);

    // Connect right side of box1 to left side of box2
    conn.setStartShapeConnectedTo(box1);
    conn.setStartShapeConnectionSiteIndex(3);   // right
    conn.setEndShapeConnectedTo(box2);
    conn.setEndShapeConnectionSiteIndex(1);     // left

    prs.save("connector.pptx", SaveFormat.PPTX);
}

Connectorvormtypen

ShapeTypeBeschrijving
ShapeType.BENT_CONNECTOR3Twee bochten van 90 graden (meest voorkomend voor flowchart-achtige diagrammen)
ShapeType.BENT_CONNECTOR2Een bocht van 90 graden
ShapeType.BENT_CONNECTOR4Drie bochten van 90 graden
ShapeType.STRAIGHT_CONNECTOR1Directe rechte lijn
ShapeType.CURVED_CONNECTOR2Enkele gladde curve
ShapeType.CURVED_CONNECTOR3Dubbele bocht curve

Top-naar-Beneden Verbinding 

import org.aspose.slides.foss.Presentation;
import org.aspose.slides.foss.ShapeType;
import org.aspose.slides.foss.export.SaveFormat;

try (Presentation prs = new Presentation()) {
    var slide = prs.getSlides().get(0);

    var top = slide.getShapes().addAutoShape(ShapeType.RECTANGLE, 250, 80, 200, 60);
    top.addTextFrame("Decision");

    var bottom = slide.getShapes().addAutoShape(ShapeType.RECTANGLE, 250, 300, 200, 60);
    bottom.addTextFrame("Action");

    var conn = slide.getShapes().addConnector(ShapeType.BENT_CONNECTOR3, 0, 0, 10, 10);
    conn.setStartShapeConnectedTo(top);
    conn.setStartShapeConnectionSiteIndex(2);    // bottom of top box
    conn.setEndShapeConnectedTo(bottom);
    conn.setEndShapeConnectionSiteIndex(0);      // top of bottom box

    prs.save("vertical-connector.pptx", SaveFormat.PPTX);
}

Stroomschema met meerdere connectoren 

import org.aspose.slides.foss.Presentation;
import org.aspose.slides.foss.ShapeType;
import org.aspose.slides.foss.export.SaveFormat;
import org.aspose.slides.foss.IAutoShape;
import org.aspose.slides.foss.ISlide;

try (Presentation prs = new Presentation()) {
    var slide = prs.getSlides().get(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);
}

static IAutoShape addBox(ISlide slide, String text, float x, float y) {
    var s = slide.getShapes().addAutoShape(ShapeType.RECTANGLE, x, y, 160, 50);
    s.addTextFrame(text);
    return s;
}

static void connect(ISlide slide, IAutoShape s1, int site1, IAutoShape s2, int site2) {
    var conn = slide.getShapes().addConnector(ShapeType.BENT_CONNECTOR3, 0, 0, 10, 10);
    conn.setStartShapeConnectedTo(s1);
    conn.setStartShapeConnectionSiteIndex(site1);
    conn.setEndShapeConnectedTo(s2);
    conn.setEndShapeConnectionSiteIndex(site2);
}

Een connector opmaken

Connectoren ondersteunen dezelfde getLineFormat() eigenschappen als andere vormen:

import org.aspose.slides.foss.Presentation;
import org.aspose.slides.foss.ShapeType;
import org.aspose.slides.foss.LineDashStyle;
import org.aspose.slides.foss.drawing.Color;
import org.aspose.slides.foss.export.SaveFormat;

try (Presentation prs = new Presentation()) {
    var slide = prs.getSlides().get(0);
    var box1 = slide.getShapes().addAutoShape(ShapeType.RECTANGLE, 50, 150, 150, 60);
    var box2 = slide.getShapes().addAutoShape(ShapeType.RECTANGLE, 400, 150, 150, 60);

    var conn = slide.getShapes().addConnector(ShapeType.BENT_CONNECTOR3, 0, 0, 10, 10);
    conn.setStartShapeConnectedTo(box1);
    conn.setStartShapeConnectionSiteIndex(3);
    conn.setEndShapeConnectedTo(box2);
    conn.setEndShapeConnectionSiteIndex(1);

    // Style the connector line
    conn.getLineFormat().setWidth(2.5);
    conn.getLineFormat().setDashStyle(LineDashStyle.DASH);
    conn.getLineFormat().getFillFormat().getSolidFillColor().setColor(Color.fromArgb(0, 0, 139));

    prs.save("styled-connector.pptx", SaveFormat.PPTX);
}
