## **Overview**

Aspose.Slides allows you to add line shapes to PowerPoint slides programmatically. This article shows how to create a simple line and how to customize a line so it appears as an arrow.

You will learn how to add a line shape to a slide, adjust its visual appearance, and save the updated presentation. The examples focus on practical line formatting settings such as style, width, dash pattern, arrowhead options, and fill color.

## **Create a Plain Line**

To add a simple plain line to a selected slide of the presentation, please follow the steps below:

- Create an instance of [Presentation](https://reference.aspose.com/slides/php-java/aspose.slides/Presentation) class.
- Obtain the reference of a slide by using its Index.
- Add an AutoShape of Line type using [addAutoShape](https://reference.aspose.com/slides/php-java/aspose.slides/shapecollection/#addAutoShape) method exposed by [ShapeCollection](https://reference.aspose.com/slides/php-java/aspose.slides/shapecollection/) object.
- Write the modified presentation as a PPTX file.

In the example given below, we have added a line to the first slide of the presentation.

```php
  # Instantiate PresentationEx class that represents the PPTX file
  $pres = new Presentation();
  try {
    # Get the first slide
    $sld = $pres->getSlides()->get_Item(0);
    # Add an AutoShape of type line
    $sld->getShapes()->addAutoShape(ShapeType::Line, 50, 150, 300, 0);
    # Write the PPTX to Disk
    $pres->save("LineShape.pptx", SaveFormat::Pptx);
  } finally {
    if (!java_is_null($pres)) {
      $pres->dispose();
    }
  }
```

## **Create an Arrow-Shaped Line**

Aspose.Slides for PHP via Java also allows developers to configure some properties of the line to make it look more appealing. Let's try to configure few properties of a line to make it look like an arrow. Please follow the steps below to do so:

- Create an instance of [Presentation](https://reference.aspose.com/slides/php-java/aspose.slides/Presentation) class.
- Obtain the reference of a slide by using its Index.
- Add an AutoShape of Line type using [addAutoShape](https://reference.aspose.com/slides/php-java/aspose.slides/shapecollection/#addAutoShape) method exposed by [ShapeCollection](https://reference.aspose.com/slides/php-java/aspose.slides/shapecollection/) object.
- Set the [Line Style](https://reference.aspose.com/slides/php-java/aspose.slides/LineStyle) to one of the styles as offered by Aspose.Slides for PHP via Java.
- Set the Width of the line.
- Set the [Dash Style](https://reference.aspose.com/slides/php-java/aspose.slides/LineDashStyle) of the line to one of the styles offered by Aspose.Slides for PHP via Java.
- Set the [Arrow Head Style](https://reference.aspose.com/slides/php-java/aspose.slides/LineArrowheadStyle) and [Length](https://reference.aspose.com/slides/php-java/aspose.slides/LineArrowheadLength) of the start point of the line.
- Set the [Arrow Head Style](https://reference.aspose.com/slides/php-java/aspose.slides/LineArrowheadStyle) and [Length](https://reference.aspose.com/slides/php-java/aspose.slides/LineArrowheadLength) of the end point of the line.
- Write the modified presentation as a PPTX file.

```php
  # Instantiate PresentationEx class that represents the PPTX file
  $pres = new Presentation();
  try {
    # Get the first slide
    $sld = $pres->getSlides()->get_Item(0);
    # Add an AutoShape of type line
    $shp = $sld->getShapes()->addAutoShape(ShapeType::Line, 50, 150, 300, 0);
    # Apply some formatting on the line
    $shp->getLineFormat()->setStyle(LineStyle->ThickBetweenThin);
    $shp->getLineFormat()->setWidth(10);
    $shp->getLineFormat()->setDashStyle(LineDashStyle->DashDot);
    $shp->getLineFormat()->setBeginArrowheadLength(LineArrowheadLength->Short);
    $shp->getLineFormat()->setBeginArrowheadStyle(LineArrowheadStyle->Oval);
    $shp->getLineFormat()->setEndArrowheadLength(LineArrowheadLength->Long);
    $shp->getLineFormat()->setEndArrowheadStyle(LineArrowheadStyle->Triangle);
    $shp->getLineFormat()->getFillFormat()->setFillType(FillType::Solid);
    $shp->getLineFormat()->getFillFormat()->getSolidFillColor()->setColor(new java("java.awt.Color", PresetColor->Maroon));
    # Write the PPTX to Disk
    $pres->save("LineShape.pptx", SaveFormat::Pptx);
  } finally {
    if (!java_is_null($pres)) {
      $pres->dispose();
    }
  }
```

## **FAQ**

### Can I convert a regular line into a connector so it "snaps" to shapes?

No. A regular line (an [AutoShape](https://reference.aspose.com/slides/php-java/aspose.slides/autoshape/) of type [Line](https://reference.aspose.com/slides/php-java/aspose.slides/shapetype/)) does not automatically become a connector. To make it snap to shapes, use the dedicated [Connector](https://reference.aspose.com/slides/php-java/aspose.slides/connector/) type and the [corresponding APIs](/slides/php-java/connector/) for connections.

### What should I do if a line’s properties are inherited from the theme and it’s hard to determine the final values?

[Read the effective properties](/slides/php-java/shape-effective-properties/) through the `LineFormatEffectiveData`/`LineFillFormatEffectiveData`—these already account for inheritance and theme styles.

### Can I lock a line against editing (moving, resizing)?

Yes. Shapes provide [lock objects](https://reference.aspose.com/slides/php-java/aspose.slides/autoshape/getautoshapelock/) that let you disallow editing operations.
