連接線

本文示範如何使用 Aspose.Slides for Node.js via Java 連接形狀與連接線，並變更其目標。

新增連接線

在投影片的兩個點之間插入連接線形狀。

function addConnector() {
    let presentation = new aspose.slides.Presentation();
    try {
        let slide = presentation.getSlides().get_Item(0);

        let connector = slide.getShapes().addConnector(aspose.slides.ShapeType.BentConnector2, 0, 0, 100, 100);

        presentation.save("connector.pptx", aspose.slides.SaveFormat.Pptx);
    } finally {
        presentation.dispose();
    }
}

取得連接線

取得已添加至投影片的第一個連接線形狀。

function accessConnector() {
    let presentation = new aspose.slides.Presentation("connector.pptx");
    try {
        let slide = presentation.getSlides().get_Item(0);

        // 取得投影片上的第一個連接線。
        let connector = null;
        for (let i = 0; i < slide.getShapes().size(); i++) {
            let shape = slide.getShapes().get_Item(i);
            if (java.instanceOf(shape, "com.aspose.slides.IConnector")) {
                connector = shape;
                break;
            }
        }
    } finally {
        presentation.dispose();
    }
}

移除連接線

從投影片中刪除連接線。

function removeConnector() {
    let presentation = new aspose.slides.Presentation("connector.pptx");
    try {
        let slide = presentation.getSlides().get_Item(0);

        // 假設第一個圖形是連接線並將其移除。
        slide.getShapes().removeAt(0);

        presentation.save("connector_removed.pptx", aspose.slides.SaveFormat.Pptx);
    } finally {
        presentation.dispose();
    }
}

重新連接形狀

透過指定起點與終點目標，將連接線附加到兩個形狀上。

function reconnectShapes() {
    let presentation = new aspose.slides.Presentation();
    try {
        let slide = presentation.getSlides().get_Item(0);

        let shape1 = slide.getShapes().addAutoShape(aspose.slides.ShapeType.Rectangle, 0, 0, 50, 50);
        let shape2 = slide.getShapes().addAutoShape(aspose.slides.ShapeType.Rectangle, 100, 100, 50, 50);

        let connector = slide.getShapes().addConnector(aspose.slides.ShapeType.BentConnector2, 0, 0, 100, 100);

        connector.setStartShapeConnectedTo(shape1);
        connector.setEndShapeConnectedTo(shape2);
    } finally {
        presentation.dispose();
    }
}
