使用 PHP 管理演示文稿中的连接器

本页内容简介

了解如何使用 Aspose.Slides for PHP（via Java）添加、附加、重新路由、调整和检查直线、弯曲和曲线 PowerPoint 连接器。

概述

连接线是可以在任一形状移动时仍然连接到两个形状的线。它的两端连接到连接点，在 PowerPoint 中以绿色点表示。某些弯曲和曲线连接线还会公开调整点，以橙色点显示，用于控制各个连接线段的位置。

Aspose.Slides 通过 Connector 类来表示连接线。您可以创建它们，将两端附加到形状，选择连接点，重新路由它们，并修改具有调整点的连接线的几何形状。

连接器类型

ShapeType 类包含直线、弯曲和曲线连接器预设。下表显示了可用的连接器几何形状以及每个预设定义的调整点数量。

连接器	图像	调整点数量
ShapeType::Line		0
ShapeType::StraightConnector1		0
ShapeType::BentConnector2		0
ShapeType::BentConnector3		1
ShapeType::BentConnector4		2
ShapeType::BentConnector5		3
ShapeType::CurvedConnector2		0
ShapeType::CurvedConnector3		1
ShapeType::CurvedConnector4		2
ShapeType::CurvedConnector5		3

调整点的数量和含义是所选连接器预设的一部分。不要假设两种不同的连接器类型公开相同的集合布局。

连接两个形状

使用 ShapeCollection::addConnector 添加连接线，使用 Connector::setStartShapeConnectedTo 和 Connector::setEndShapeConnectedTo 将其两端附加。两端都附加后， Connector::reroute 选择形状之间的短路径。

以下示例使用弯曲连接器将椭圆和矩形连接起来：

use aspose\slides\Presentation;
use aspose\slides\SaveFormat;
use aspose\slides\ShapeType;

$presentation = new Presentation();
try {
    $slide = $presentation->getSlides()->get_Item(0);

    $ellipse = $slide->getShapes()->addAutoShape(ShapeType::Ellipse, 40, 80, 120, 80);
    $rectangle = $slide->getShapes()->addAutoShape(ShapeType::Rectangle, 320, 240, 140, 80);
    $connector = $slide->getShapes()->addConnector(ShapeType::BentConnector2, 0, 0, 10, 10);

    $connector->setStartShapeConnectedTo($ellipse);
    $connector->setEndShapeConnectedTo($rectangle);
    $connector->reroute();

    $presentation->save("connected-shapes.pptx", SaveFormat::Pptx);
} finally {
    $presentation->dispose();
}

Warning

调用 reroute 可能会更改 Connector::setStartShapeConnectionSiteIndex 和 Connector::setEndShapeConnectionSiteIndex 的值。如果这些连接点必须保持固定，请在重新路由后分配特定的连接点。

选择连接点

每个可连接的形状通过 Shape::getConnectionSiteCount 报告其连接点数量。在将其分配给连接线的端点之前，请验证首选的零基索引；连接点数量因形状几何而异。

以下示例在椭圆上存在该连接点时，将连接线附加到椭圆的特定连接点：

use aspose\slides\Presentation;
use aspose\slides\SaveFormat;
use aspose\slides\ShapeType;

$presentation = new Presentation();
try {
    $slide = $presentation->getSlides()->get_Item(0);

    $ellipse = $slide->getShapes()->addAutoShape(ShapeType::Ellipse, 40, 80, 120, 80);
    $rectangle = $slide->getShapes()->addAutoShape(ShapeType::Rectangle, 320, 240, 140, 80);
    $connector = $slide->getShapes()->addConnector(ShapeType::BentConnector3, 0, 0, 10, 10);

    $connector->setStartShapeConnectedTo($ellipse);
    $connector->setEndShapeConnectedTo($rectangle);

    $preferredSiteIndex = 2;
    $connectionSiteCount = java_values($ellipse->getConnectionSiteCount());
    if ($preferredSiteIndex < $connectionSiteCount) {
        $connector->setStartShapeConnectionSiteIndex($preferredSiteIndex);
    } else {
        echo "The ellipse has only " . $connectionSiteCount . " connection sites." . PHP_EOL;
    }

    $presentation->save("specific-connection-site.pptx", SaveFormat::Pptx);
} finally {
    $presentation->dispose();
}

调整连接点

具有调整点的连接线通过 GeometryShape::getAdjustments 公开它们。在使用 AdjustValue::setRawValue 更改之前，检查每个 AdjustValue 并查看其 AdjustValue::getType 值。关于识别预设形状调整的通用规则，请参阅 Shape Manipulation。

连接线调整的数量、顺序、含义和有效值范围取决于连接线预设。调整类型是只读的，而调整值是可写的。只读的 AdjustValue::getName 方法提供额外的标识，当一个连接线包含多个相同语义类型的调整时尤为有用。

绕过障碍物的路线

在以下布局中，两个形状之间的 BentConnector5 连接线穿过第三个形状：

以下代码创建了受阻的连接线：

use aspose\slides\FillType;
use aspose\slides\LineArrowheadStyle;
use aspose\slides\Presentation;
use aspose\slides\SaveFormat;
use aspose\slides\ShapeType;
use java\awt\Color;

$presentation = new Presentation();
try {
    $slide = $presentation->getSlides()->get_Item(0);

    $slide->getShapes()->addAutoShape(ShapeType::Rectangle, 300, 150, 150, 75);
    $sourceShape = $slide->getShapes()->addAutoShape(ShapeType::Rectangle, 500, 400, 100, 50);
    $targetShape = $slide->getShapes()->addAutoShape(ShapeType::Rectangle, 100, 100, 70, 30);
    $connector = $slide->getShapes()->addConnector(ShapeType::BentConnector5, 20, 20, 400, 300);

    $connector->getLineFormat()->setEndArrowheadStyle(LineArrowheadStyle::Triangle);
    $connector->getLineFormat()->getFillFormat()->setFillType(FillType::Solid);
    $connector->getLineFormat()->getFillFormat()->getSolidFillColor()->setColor(new Color(0, 0, 0));
    $connector->setStartShapeConnectedTo($sourceShape);
    $connector->setEndShapeConnectedTo($targetShape);
    $connector->setStartShapeConnectionSiteIndex(2);

    $presentation->save("connector-obstruction.pptx", SaveFormat::Pptx);
} finally {
    $presentation->dispose();
}

移动垂直弯曲会改变路径，使连接线绕过障碍物：

不要假设集合索引 1 总是表示垂直弯曲，此示例搜索 ConnectorBendPositionY 并仅在出现预期语义类型时才进行更改：

use aspose\slides\FillType;
use aspose\slides\LineArrowheadStyle;
use aspose\slides\Presentation;
use aspose\slides\SaveFormat;
use aspose\slides\ShapeAdjustmentType;
use aspose\slides\ShapeType;
use java\awt\Color;

$presentation = new Presentation();
try {
    $slide = $presentation->getSlides()->get_Item(0);

    $slide->getShapes()->addAutoShape(ShapeType::Rectangle, 300, 150, 150, 75);
    $sourceShape = $slide->getShapes()->addAutoShape(ShapeType::Rectangle, 500, 400, 100, 50);
    $targetShape = $slide->getShapes()->addAutoShape(ShapeType::Rectangle, 100, 100, 70, 30);
    $connector = $slide->getShapes()->addConnector(ShapeType::BentConnector5, 20, 20, 400, 300);

    $connector->getLineFormat()->setEndArrowheadStyle(LineArrowheadStyle::Triangle);
    $connector->getLineFormat()->getFillFormat()->setFillType(FillType::Solid);
    $connector->getLineFormat()->getFillFormat()->getSolidFillColor()->setColor(new Color(0, 0, 0));
    $connector->setStartShapeConnectedTo($sourceShape);
    $connector->setEndShapeConnectedTo($targetShape);
    $connector->setStartShapeConnectionSiteIndex(2);

    $verticalBend = null;
    $adjustmentCount = java_values($connector->getAdjustments()->size());
    for ($adjustmentIndex = 0; $adjustmentIndex < $adjustmentCount; $adjustmentIndex++) {
        $adjustment = $connector->getAdjustments()->get_Item($adjustmentIndex);
        $adjustmentName = java_values($adjustment->getName());
        $adjustmentType = java_values($adjustment->getType());
        $rawValue = java_values($adjustment->getRawValue());
        echo $adjustmentName . ": " . $adjustmentType . ", raw value = " . $rawValue . PHP_EOL;
        if ($adjustmentType == ShapeAdjustmentType::ConnectorBendPositionY) {
            $verticalBend = $adjustment;
            break;
        }
    }

    if ($verticalBend === null) {
        echo "The connector does not expose a vertical bend adjustment." . PHP_EOL;
    } else {
        $verticalBend->setRawValue(60000);
        $presentation->save("connector-obstruction-fixed.pptx", SaveFormat::Pptx);
    }
} finally {
    $presentation->dispose();
}

BentConnector5 有两个 ConnectorBendPositionX 调整和一个 ConnectorBendPositionY 调整。如果所需的类型出现多次，请在选择之前检查 getName 以及该预设的已知几何形状。如果某个调整报告 ShapeAdjustmentType::Custom，则将其含义和范围视为特定于预设，在未明确该约定前不要更改它。

将调整值与连接器几何关联

对于弯曲连接器，调整值可用于估算各段的位置。这些计算特定于连接器预设：

• BentConnector4 通常会公开一个 ConnectorBendPositionX 调整和一个 ConnectorBendPositionY 调整。
• 对于这些弯曲位置，将 getRawValue 返回的值除以 100000 可得到连接器框宽度或高度的比例，如下例所示。
• 连接器框可以旋转或翻转，因此在与幻灯片坐标比较之前必须对框坐标进行转换。

以下示例首先使用 getType 标识调整。它们不将集合索引视为可移植的标识符。

未旋转的连接器

初始布局包含两个由 BentConnector4 连接的文本形状：

此示例检查连接器并获取其水平和垂直弯曲调整：

use aspose\slides\FillType;
use aspose\slides\LineArrowheadStyle;
use aspose\slides\Presentation;
use aspose\slides\ShapeType;
use java\awt\Color;

$presentation = new Presentation();
try {
    $slide = $presentation->getSlides()->get_Item(0);

    $sourceShape = $slide->getShapes()->addAutoShape(ShapeType::Rectangle, 100, 100, 60, 25);
    $sourceShape->getTextFrame()->setText("From");
    $targetShape = $slide->getShapes()->addAutoShape(ShapeType::Rectangle, 500, 100, 60, 25);
    $targetShape->getTextFrame()->setText("To");
    $connector = $slide->getShapes()->addConnector(ShapeType::BentConnector4, 20, 20, 400, 300);

    $connector->getLineFormat()->setEndArrowheadStyle(LineArrowheadStyle::Triangle);
    $connector->getLineFormat()->getFillFormat()->setFillType(FillType::Solid);
    $connector->getLineFormat()->getFillFormat()->getSolidFillColor()->setColor(new Color(255, 0, 0));
    $connector->getLineFormat()->setWidth(3);
    $connector->setStartShapeConnectedTo($sourceShape);
    $connector->setStartShapeConnectionSiteIndex(3);
    $connector->setEndShapeConnectedTo($targetShape);
    $connector->setEndShapeConnectionSiteIndex(2);

    $adjustmentCount = java_values($connector->getAdjustments()->size());
    for ($adjustmentIndex = 0; $adjustmentIndex < $adjustmentCount; $adjustmentIndex++) {
        $adjustment = $connector->getAdjustments()->get_Item($adjustmentIndex);
        echo $adjustment->getName() . ": " . $adjustment->getType() . ", raw value = " . $adjustment->getRawValue() . PHP_EOL;
    }
} finally {
    $presentation->dispose();
}

要更改两个弯曲，请定位每个预期类型，并在找到两者后才修改值：

use aspose\slides\Presentation;
use aspose\slides\SaveFormat;
use aspose\slides\ShapeAdjustmentType;
use aspose\slides\ShapeType;

$presentation = new Presentation();
try {
    $slide = $presentation->getSlides()->get_Item(0);

    $sourceShape = $slide->getShapes()->addAutoShape(ShapeType::Rectangle, 100, 100, 60, 25);
    $targetShape = $slide->getShapes()->addAutoShape(ShapeType::Rectangle, 500, 100, 60, 25);
    $connector = $slide->getShapes()->addConnector(ShapeType::BentConnector4, 20, 20, 400, 300);
    $connector->setStartShapeConnectedTo($sourceShape);
    $connector->setStartShapeConnectionSiteIndex(3);
    $connector->setEndShapeConnectedTo($targetShape);
    $connector->setEndShapeConnectionSiteIndex(2);

    $horizontalBend = null;
    $verticalBend = null;
    $adjustmentCount = java_values($connector->getAdjustments()->size());
    for ($adjustmentIndex = 0; $adjustmentIndex < $adjustmentCount; $adjustmentIndex++) {
        $adjustment = $connector->getAdjustments()->get_Item($adjustmentIndex);
        $adjustmentType = java_values($adjustment->getType());
        if ($adjustmentType == ShapeAdjustmentType::ConnectorBendPositionX) {
            $horizontalBend = $adjustment;
        } elseif ($adjustmentType == ShapeAdjustmentType::ConnectorBendPositionY) {
            $verticalBend = $adjustment;
        }
    }

    if ($horizontalBend === null || $verticalBend === null) {
        echo "The connector does not expose the expected bend adjustments." . PHP_EOL;
    } else {
        $horizontalBendValue = java_values($horizontalBend->getRawValue());
        $verticalBendValue = java_values($verticalBend->getRawValue());
        $horizontalBendValue += 20000;
        $verticalBendValue += 200000;
        $horizontalBend->setRawValue($horizontalBendValue);
        $verticalBend->setRawValue($verticalBendValue);
        $presentation->save("connector-adjusted.pptx", SaveFormat::Pptx);
    }
} finally {
    $presentation->dispose();
}

结果是水平和垂直段已经移动的连接器：

一旦知道语义类型，就可以将它们的值转换为连接器框坐标。此示例在由两个弯曲调整控制的垂直段上绘制一个细矩形：

use aspose\slides\Presentation;
use aspose\slides\SaveFormat;
use aspose\slides\ShapeAdjustmentType;
use aspose\slides\ShapeType;

$presentation = new Presentation();
try {
    $slide = $presentation->getSlides()->get_Item(0);

    $sourceShape = $slide->getShapes()->addAutoShape(ShapeType::Rectangle, 100, 100, 60, 25);
    $targetShape = $slide->getShapes()->addAutoShape(ShapeType::Rectangle, 500, 100, 60, 25);
    $connector = $slide->getShapes()->addConnector(ShapeType::BentConnector4, 20, 20, 400, 300);
    $connector->setStartShapeConnectedTo($sourceShape);
    $connector->setStartShapeConnectionSiteIndex(3);
    $connector->setEndShapeConnectedTo($targetShape);
    $connector->setEndShapeConnectionSiteIndex(2);

    $horizontalBend = null;
    $verticalBend = null;
    $adjustmentCount = java_values($connector->getAdjustments()->size());
    for ($adjustmentIndex = 0; $adjustmentIndex < $adjustmentCount; $adjustmentIndex++) {
        $adjustment = $connector->getAdjustments()->get_Item($adjustmentIndex);
        $adjustmentType = java_values($adjustment->getType());
        if ($adjustmentType == ShapeAdjustmentType::ConnectorBendPositionX) {
            $horizontalBend = $adjustment;
        } elseif ($adjustmentType == ShapeAdjustmentType::ConnectorBendPositionY) {
            $verticalBend = $adjustment;
        }
    }

    if ($horizontalBend === null || $verticalBend === null) {
        echo "The connector does not expose the expected bend adjustments." . PHP_EOL;
    } else {
        $connectorX = java_values($connector->getX());
        $connectorY = java_values($connector->getY());
        $connectorWidth = java_values($connector->getWidth());
        $connectorHeight = java_values($connector->getHeight());
        $horizontalBendValue = java_values($horizontalBend->getRawValue());
        $verticalBendValue = java_values($verticalBend->getRawValue());
        $x = $connectorX + $connectorWidth * $horizontalBendValue / 100000;
        $y = $connectorY;
        $height = $connectorHeight * $verticalBendValue / 100000;
        $slide->getShapes()->addAutoShape(ShapeType::Rectangle, $x, $y, 1, $height);
        $presentation->save("connector-segment-guide.pptx", SaveFormat::Pptx);
    }
} finally {
    $presentation->dispose();
}

引导形状标记了计算得到的段：

旋转或翻转的连接器

当相同的连接器几何垂直定位时，其 Shape::getFrame、ShapeFrame::getFlipH 和 ShapeFrame::getFlipV 值会影响从连接器框坐标到幻灯片坐标的转换。

此示例创建并调整垂直方向的连接器：

use aspose\slides\FillType;
use aspose\slides\LineArrowheadStyle;
use aspose\slides\Presentation;
use aspose\slides\SaveFormat;
use aspose\slides\ShapeAdjustmentType;
use aspose\slides\ShapeType;
use java\awt\Color;

$presentation = new Presentation();
try {
    $slide = $presentation->getSlides()->get_Item(0);

    $sourceShape = $slide->getShapes()->addAutoShape(ShapeType::Rectangle, 100, 100, 60, 25);
    $sourceShape->getTextFrame()->setText("From");
    $targetShape = $slide->getShapes()->addAutoShape(ShapeType::Rectangle, 100, 400, 60, 25);
    $targetShape->getTextFrame()->setText("To 1");
    $connector = $slide->getShapes()->addConnector(ShapeType::BentConnector4, 20, 20, 400, 300);

    $connector->getLineFormat()->setEndArrowheadStyle(LineArrowheadStyle::Triangle);
    $connector->getLineFormat()->getFillFormat()->setFillType(FillType::Solid);
    $connector->getLineFormat()->getFillFormat()->getSolidFillColor()->setColor(new Color(102, 205, 170));
    $connector->getLineFormat()->setWidth(3);
    $connector->setStartShapeConnectedTo($sourceShape);
    $connector->setStartShapeConnectionSiteIndex(2);
    $connector->setEndShapeConnectedTo($targetShape);
    $connector->setEndShapeConnectionSiteIndex(3);

    $adjustmentCount = java_values($connector->getAdjustments()->size());
    for ($adjustmentIndex = 0; $adjustmentIndex < $adjustmentCount; $adjustmentIndex++) {
        $adjustment = $connector->getAdjustments()->get_Item($adjustmentIndex);
        $adjustmentType = java_values($adjustment->getType());
        if ($adjustmentType == ShapeAdjustmentType::ConnectorBendPositionX) {
            $rawValue = java_values($adjustment->getRawValue());
            $adjustment->setRawValue($rawValue + 20000);
        } elseif ($adjustmentType == ShapeAdjustmentType::ConnectorBendPositionY) {
            $rawValue = java_values($adjustment->getRawValue());
            $adjustment->setRawValue($rawValue + 200000);
        }
    }

    $presentation->save("vertical-connector-adjusted.pptx", SaveFormat::Pptx);
} finally {
    $presentation->dispose();
}

调整后的连接器垂直显示在形状之间：

对于任意旋转角度 alpha，将连接器框点 (x, y) 绕框中心 (x0, y0) 旋转：

X = (x - x0) * cos(alpha) - (y - y0) * sin(alpha) + x0

Y = (x - x0) * sin(alpha) + (y - y0) * cos(alpha) + y0

以下代码处理本示例中使用的 90 度方向，并在相应的连接器段上绘制红色引导线：

use aspose\slides\FillType;
use aspose\slides\NullableBool;
use aspose\slides\Presentation;
use aspose\slides\SaveFormat;
use aspose\slides\ShapeAdjustmentType;
use aspose\slides\ShapeType;
use java\awt\Color;

$presentation = new Presentation();
try {
    $slide = $presentation->getSlides()->get_Item(0);

    $sourceShape = $slide->getShapes()->addAutoShape(ShapeType::Rectangle, 100, 100, 60, 25);
    $targetShape = $slide->getShapes()->addAutoShape(ShapeType::Rectangle, 100, 400, 60, 25);
    $connector = $slide->getShapes()->addConnector(ShapeType::BentConnector4, 20, 20, 400, 300);
    $connector->setStartShapeConnectedTo($sourceShape);
    $connector->setStartShapeConnectionSiteIndex(2);
    $connector->setEndShapeConnectedTo($targetShape);
    $connector->setEndShapeConnectionSiteIndex(3);

    $horizontalBend = null;
    $verticalBend = null;
    $adjustmentCount = java_values($connector->getAdjustments()->size());
    for ($adjustmentIndex = 0; $adjustmentIndex < $adjustmentCount; $adjustmentIndex++) {
        $adjustment = $connector->getAdjustments()->get_Item($adjustmentIndex);
        $adjustmentType = java_values($adjustment->getType());
        if ($adjustmentType == ShapeAdjustmentType::ConnectorBendPositionX) {
            $horizontalBend = $adjustment;
        } elseif ($adjustmentType == ShapeAdjustmentType::ConnectorBendPositionY) {
            $verticalBend = $adjustment;
        }
    }

    if ($horizontalBend === null || $verticalBend === null) {
        echo "The connector does not expose the expected bend adjustments." . PHP_EOL;
    } else {
        $horizontalBendValue = java_values($horizontalBend->getRawValue());
        $verticalBendValue = java_values($verticalBend->getRawValue());
        $horizontalBendValue += 20000;
        $verticalBendValue += 200000;
        $horizontalBend->setRawValue($horizontalBendValue);
        $verticalBend->setRawValue($verticalBendValue);

        $frame = $connector->getFrame();
        $connectorX = java_values($connector->getX());
        $connectorY = java_values($connector->getY());
        $connectorWidth = java_values($connector->getWidth());
        $connectorHeight = java_values($connector->getHeight());
        $flipH = java_values($frame->getFlipH()) == NullableBool::True;
        $flipV = java_values($frame->getFlipV()) == NullableBool::True;
        $centerX = java_values($frame->getCenterX());
        $centerY = java_values($frame->getCenterY());

        $x = $connectorX;
        $y = $connectorY;
        if ($flipH) {
            $x += $connectorWidth;
        }
        if ($flipV) {
            $y += $connectorHeight;
        }

        $x += $connectorWidth * $horizontalBendValue / 100000;
        $rotatedX = $centerX - $y + $centerY;
        $rotatedY = $x - $centerX + $centerY;
        $segmentWidth = $connectorHeight * $verticalBendValue / 100000;
        $guide = $slide->getShapes()->addAutoShape(ShapeType::Rectangle, $rotatedX, $rotatedY, $segmentWidth, 1);
        $guide->getLineFormat()->getFillFormat()->setFillType(FillType::Solid);
        $guide->getLineFormat()->getFillFormat()->getSolidFillColor()->setColor(new Color(255, 0, 0));

        $presentation->save("rotated-connector-segment-guide.pptx", SaveFormat::Pptx);
    }
} finally {
    $presentation->dispose();
}

坐标转换后，红色引导线标记了计算得到的段：

这些公式描述的是示例中使用的预设，而非通用的连接器模型。在将相同计算应用于不同预设之前，请验证调整类型、框的方向和数值范围。

查找连接器方向角

可以根据直线连接器的宽度和高度，并考虑水平和垂直翻转来计算其方向。以下示例报告了相对于幻灯片坐标中正水平轴的顺时针角度：

use aspose\slides\NullableBool;
use aspose\slides\Presentation;
use aspose\slides\ShapeType;

$presentation = new Presentation();
try {
    $slide = $presentation->getSlides()->get_Item(0);
    $connector = $slide->getShapes()->addConnector(ShapeType::StraightConnector1, 100, 100, 200, 100);

    $frame = $connector->getFrame();
    $flipH = java_values($frame->getFlipH()) == NullableBool::True;
    $flipV = java_values($frame->getFlipV()) == NullableBool::True;
    $width = java_values($connector->getWidth());
    $height = java_values($connector->getHeight());
    $deltaX = $width * ($flipH ? -1 : 1);
    $deltaY = $height * ($flipV ? -1 : 1);
    $angle = atan2($deltaY, $deltaX) * 180.0 / pi();

    if ($angle < 0) {
        $angle += 360;
    }

    printf("Connector direction: %.2f degrees%s", $angle, PHP_EOL);
} finally {
    $presentation->dispose();
}

常见问题

如何判断连接器是否可以附加到形状？

检查形状的 Shape::getConnectionSiteCount 值。正值表示该形状公开连接点。在将选定的连接点索引分配给任一连接器端之前，请先验证该索引。

我可以通过集合索引识别连接器调整吗？

索引仅在已知的连接器预设和集合布局下才有意义。在修改值之前，请检查 AdjustValue::getType，并在同一语义类型出现多次时使用 AdjustValue::getName 作为额外信息。

删除已连接的形状会发生什么？

相应的连接器端会被分离。连接器仍保留在幻灯片上，可以删除、作为自由线定位，或重新附加到其他形状。

复制幻灯片时，连接器绑定会被保留吗？

如果在复制幻灯片时一起复制了已连接的形状，绑定通常会被保留。如果仅复制了连接器而未复制其目标形状，则必须重新附加受影响的端点。
