Connectors

Darbas su jungtukais — Aspose.Slides FOSS for Java

Jungtys yra formos, kurios vizualiai sujungia dvi kitas formas linija. Aspose.Slides FOSS for Java palaiko lenktas, tiesias ir kreivines jungtis. Jungimo taškai ant formos identifikuojami sveikais skaičiais jungimo vietų indeksai.

Jungties vietų indeksai

Kiekviena forma pateikia keturias standartines jungties vietas:

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

Lenkto jungtuko pridėjimas tarp dviejų formų

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

Jungtuko formų tipai

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