Add Rectangles to Presentations in PHP

Like previous topics, this one is also about adding a shape and this time the shape we will discuss about is Rectangle. In this topic, we have described that how developers can add simple or formatted rectangles to their slides using Aspose.Slides for PHP via Java.

Add a Rectangle to a Slide

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

• Create an instance of Presentation class.
• Obtain the reference of a slide by using its Index.
• Add an IAutoShape of Rectangle type using addAutoShape method exposed by IShapeCollection object.
• Write the modified presentation as a PPTX file.

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

  # Instantiate Prseetation class that represents the PPTX
  $pres = new Presentation();
  try {
    # Get the first slide
    $sld = $pres->getSlides()->get_Item(0);
    # Add AutoShape of ellipse type
    $shp = $sld->getShapes()->addAutoShape(ShapeType::Rectangle, 50, 150, 150, 50);
    # Write the PPTX file to disk
    $pres->save("RecShp1.pptx", SaveFormat::Pptx);
  } finally {
    if (!java_is_null($pres)) {
      $pres->dispose();
    }
  }

Add a Formatted Rectangle to a Slide

To add a formatted rectangle to a slide, please follow the steps below:

• Create an instance of Presentation class.
• Obtain the reference of a slide by using its Index.
• Add an IAutoShape of Rectangle type using addAutoShape method exposed by IShapeCollection object.
• Set the Fill Type of the Rectangle to Solid.
• Set the Color of the Rectangle using SolidFillColor.setColor method as exposed by IFillFormat object associated with the IShape object.
• Set the Color of the lines of the Rectangle.
• Set the Width of the lines of the Rectangle.
• Write the modified presentation as PPTX file.

The above steps are implemented in the example given below.

  # Instantiate Prseetation class that represents the PPTX
  $pres = new Presentation();
  try {
    # Get the first slide
    $sld = $pres->getSlides()->get_Item(0);
    # Add AutoShape of ellipse type
    $shp = $sld->getShapes()->addAutoShape(ShapeType::Rectangle, 50, 150, 150, 50);
    # Apply some formatting to ellipse shape
    $shp->getFillFormat()->setFillType(FillType::Solid);
    $shp->getFillFormat()->getSolidFillColor()->setColor(java("java.awt.Color")->GRAY);
    # Apply some formatting to the line of Ellipse
    $shp->getLineFormat()->getFillFormat()->setFillType(FillType::Solid);
    $shp->getLineFormat()->getFillFormat()->getSolidFillColor()->setColor(java("java.awt.Color")->BLACK);
    $shp->getLineFormat()->setWidth(5);
    # Write the PPTX file to disk
    $pres->save("RecShp2.pptx", SaveFormat::Pptx);
  } finally {
    if (!java_is_null($pres)) {
      $pres->dispose();
    }
  }

FAQ

How do I add a rectangle with rounded corners?

Use the rounded-corner shape type and adjust the corner radius in the shape’s properties; rounding can also be applied per corner via geometry adjustments.

How do I fill a rectangle with an image (texture)?

Select the picture fill type, provide the image source, and configure stretching/tiling modes.

Can a rectangle have shadow and glow?

Yes. Outer/inner shadow, glow, and soft edges are available with adjustable parameters.

Can I turn a rectangle into a button with a hyperlink?

Yes. Assign a hyperlink to the shape click (jump to a slide, file, web address, or e-mail).

How can I protect a rectangle from moving and changes?

Use shape locks: you can forbid moving, resizing, selection, or text editing to preserve the layout.

Can I convert a rectangle to a raster image or SVG?

Yes. You can render the shape to an image with a specified size/scale or export it as SVG for vector use.

How do I quickly get the actual (effective) properties of a rectangle considering theme and inheritance?

Use the shape’s effective properties: the API returns computed values that account for theme styles, layout, and local settings, simplifying formatting analysis.
