Manage Presentation Notes in PHP

Overview

Aspose.Slides supports removing notes slides from a presentation. In this topic, we will introduce this feature, including how to remove notes and how to apply a style to notes slides in a presentation. Aspose.Slides allows you to remove notes from any slide and also apply styling to existing notes. Developers can remove notes in the following ways:

• Remove notes from a specific slide in a presentation.
• Remove notes from all slides in a presentation.

Remove Notes from a Slide

Notes of some specific slide could be removed as shown in example below:

  # Instantiate a Presentation object that represents a presentation file
  $pres = new Presentation("presWithNotes.pptx");
  try {
    # Removing notes of first slide
    $mgr = $pres->getSlides()->get_Item(0)->getNotesSlideManager();
    $mgr->removeNotesSlide();
    # Saving presentation to disk
    $pres->save("test.pptx", SaveFormat::Pptx);
  } finally {
    if (!java_is_null($pres)) {
      $pres->dispose();
    }
  }

Remove Notes from a Presentation

Notes of all the slides of a presentation could be removed as shown in example below:

  # Instantiate a Presentation object that represents a presentation file
  $pres = new Presentation("presWithNotes.pptx");
  try {
    # Removing notes of all slides
    $mgr = null;
    for($i = 0; $i < java_values($pres->getSlides()->size()) ; $i++) {
      $mgr = $pres->getSlides()->get_Item($i)->getNotesSlideManager();
      $mgr->removeNotesSlide();
    }
    # Saving presentation to disk
    $pres->save("test.pptx", SaveFormat::Pptx);
  } finally {
    if (!java_is_null($pres)) {
      $pres->dispose();
    }
  }

Add a Notes Style

getNotesStyle method has been added to MasterNotesSlide class respectively. This property specifies the style of a notes text. The implementation is demonstrated in the example below.

  # Instantiate a Presentation object that represents a presentation file
  $pres = new Presentation("demo.pptx");
  try {
    $notesMaster = $pres->getMasterNotesSlideManager()->getMasterNotesSlide();
    if (!java_is_null($notesMaster)) {
      # Get MasterNotesSlide text style
      $notesStyle = $notesMaster->getNotesStyle();
      # Set symbol bullet for the first level paragraphs
      $paragraphFormat = $notesStyle->getLevel(0);
      $paragraphFormat::getBullet()->setType(BulletType::Symbol);
    }
    $pres->save("NotesSlideWithNotesStyle.pptx", SaveFormat::Pptx);
  } finally {
    if (!java_is_null($pres)) {
      $pres->dispose();
    }
  }

FAQ

Which API entity provides access to the notes of a specific slide?

Notes are accessed through the slide’s notes manager: the slide has a NotesSlideManager and a method that returns the notes object, or null if there are no notes.

Are there differences in notes support across the PowerPoint versions the library works with?

The library targets a broad range of Microsoft PowerPoint formats (97–newer) and ODP; notes are supported within these formats without depending on an installed copy of PowerPoint.
