Connectors

Darbas su jungtukais — Aspose.Slides FOSS for Java

Jungikliai yra formos, kurios vizualiai sujungia dvi kitas formas linija. Aspose.Slides FOSS for Java palaiko lenktus, tiesius ir kreivus jungiklius. Formos jungimo taškai identifikuojami sveikaisiais connection site indexes.

Prisijungimo vietų indeksai

Kiekviena figūra pateikia keturis standartinius jungimo taškus:

Indeksas	Pusė
`0`	Viršus
`1`	Kairė
`2`	Apačia
`3`	Dešinė

Pridedamas lenktas jungiklis tarp dviejų formų

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

Jungties formų tipai

Formos tipas	Aprašymas
`ShapeType.BENT_CONNECTOR3`	Du 90 laipsnių posūkiai (dažniausiai naudojami srauto diagramos stiliaus schemoms)
`ShapeType.BENT_CONNECTOR2`	Vienas 90 laipsnių posūkis
`ShapeType.BENT_CONNECTOR4`	Trys 90 laipsnių posūkiai
`ShapeType.STRAIGHT_CONNECTOR1`	Tiesioginė tiesi linija
`ShapeType.CURVED_CONNECTOR2`	Viena glota kreivė
`ShapeType.CURVED_CONNECTOR3`	Dvigubo posūkio kreivė
