连接器

本文演示了如何使用 Aspose.Slides for Node.js via Java 将形状通过连接线连接并更改其目标。

Add a Connector

在幻灯片的两个点之间插入一个连接线形状。

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();
    }
}

Access a Connector

检索已添加到幻灯片的第一个连接线形状。

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

        // 访问幻灯片上的第一个连接器。
        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();
    }
}

Remove a Connector

从幻灯片中删除连接线。

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

        // 假设第一个形状是连接器并将其移除。
        slide.getShapes().removeAt(0);

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

Reconnect Shapes

通过分配起始和结束目标，将连接线附加到两个形状上。

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();
    }
}
