  $pres = new Presentation("Presentation.pptx");
  try {
    $textHighlightingOptions = new TextHighlightingOptions();
    $textHighlightingOptions->setWholeWordsOnly(true);
    $pres->getSlides()->get_Item(0)->getShapes()->get_Item(0)->getTextFrame()->highlightText("title", java("java.awt.Color")->BLUE);// Hervorheben aller Wörter 'important'

    $pres->getSlides()->get_Item(0)->getShapes()->get_Item(0)->getTextFrame()->highlightText("to", java("java.awt.Color")->MAGENTA, $textHighlightingOptions);// Hervorheben aller einzelnen 'the'-Vorkommen

    $pres->save("OutputPresentation-highlight.pptx", SaveFormat::Pptx);
  } finally {
    if (!java_is_null($pres)) {
      $pres->dispose();
    }
  }

Text mit regulärem Ausdruck hervorheben

Hintergrundfarbe des Textes festlegen

Aspose.Slides allows you to specify your preferred color for the background of a text.

This PHP code shows you how to set the background color for an entire text:

  $pres = new Presentation();
  try {
    $autoShape = $pres->getSlides()->get_Item(0)->getShapes()->addAutoShape(ShapeType::Rectangle, 50, 50, 200, 100);
    $autoShape->getTextFrame()->getParagraphs()->clear();
    $para = new Paragraph();
    $portion1 = new Portion("Black");
    $portion1->getPortionFormat()->setFontBold(NullableBool::True);
    $portion2 = new Portion(" Red ");
    $portion3 = new Portion("Black");
    $portion3->getPortionFormat()->setFontBold(NullableBool::True);
    $para->getPortions()->add($portion1);
    $para->getPortions()->add($portion2);
    $para->getPortions()->add($portion3);
    $autoShape->getTextFrame()->getParagraphs()->add($para);
    $pres->save("text.pptx", SaveFormat::Pptx);
  } finally {
    if (!java_is_null($pres)) {
      $pres->dispose();
    }
  }
  $presentation = new Presentation("text.pptx");
  try {
    $autoShape = $presentation->getSlides()->get_Item(0)->getShapes()->get_Item(0);
    StreamSupport->stream($autoShape->getTextFrame()->getParagraphs()->spliterator(), false)->map(( p) -> $p->getPortions())->forEach(( c) -> $c->forEach(( ic) -> $ic->getPortionFormat()->getHighlightColor()->setColor($Color.BLUE)));

Textabsätze ausrichten

Text formatting is one of the key elements while creating any kind of documents or presentations. We know that Aspose.Slides for PHP via Java supports adding text to slides but in this topic, we will see that how can we control the alignment of the text paragraphs in a slide. Please follow the steps below to align text paragraphs using Aspose.Slides for PHP via Java:

  1. Create an instance of Presentation class.
  2. Obtain the reference of a slide by using its Index.
  3. Access the Placeholder shapes present in the slide and typecast them as a AutoShape.
  4. Get the Paragraph (that needs to be aligned) from the TextFrame exposed by AutoShape.
  5. Align the Paragraph. A paragraph can be aligned to Right, Left, Center & Justify.
  6. Write the modified presentation as a PPTX file.

The implementation of the above steps is given below.

  # Instanziieren eines Presentation-Objekts, das eine PPTX-Datei darstellt
  $pres = new Presentation("ParagraphsAlignment.pptx");
  try {
    # Zugriff auf die erste Folie
    $slide = $pres->getSlides()->get_Item(0);
    # Zugriff auf den ersten und zweiten Platzhalter in der Folie und Typumwandlung zu AutoShape
    $tf1 = $slide->getShapes()->get_Item(0)->getTextFrame();
    $tf2 = $slide->getShapes()->get_Item(1)->getTextFrame();
    # Ändern des Textes in beiden Platzhaltern
    $tf1->setText("Center Align by Aspose");
    $tf2->setText("Center Align by Aspose");
    # Abrufen des ersten Absatzes der Platzhalter
    $para1 = $tf1->getParagraphs()->get_Item(0);
    $para2 = $tf2->getParagraphs()->get_Item(0);
    # Ausrichten des Textabsatzes zur Mitte
    $para1->getParagraphFormat()->setAlignment(TextAlignment->Center);
    $para2->getParagraphFormat()->setAlignment(TextAlignment->Center);
    # Schreiben der Präsentation als PPTX-Datei
    $pres->save("Centeralign_out.pptx", SaveFormat::Pptx);
  } finally {
    if (!java_is_null($pres)) {
      $pres->dispose();
    }
  }

Zeilenabstand eines Absatzes

Aspose.Slides provides properties under ParagraphFormat—SpaceAfter, SpaceBefore and SpaceWithin—that allow you to manage the line spacing for a paragraph. The three properties are used this way:

  • To specify the line spacing for a paragraph in percentage, use a positive value.
  • To specify the line spacing for a paragraph in points, use a negative value.

For example, you can apply a 16pt line spacing for a paragraph by setting the SpaceBefore property to -16.

This is how you specify the line spacing for a specific paragraph:

  1. Load a presentation containing an AutoShape with some text in it.
  2. Get a slide’s reference through its index.
  3. Access the TextFrame.
  4. Access the Paragraph.
  5. Set the Paragraph properties.
  6. Save the presentation.

This PHP code shows you how to specify the line spacing for a paragraph:

  # Instanz der Presentation-Klasse erstellen
  $pres = new Presentation("Fonts.pptx");
  try {
    # Referenz einer Folie über ihren Index erhalten
    $sld = $pres->getSlides()->get_Item(0);
    # Auf das TextFrame zugreifen
    $tf1 = $sld->getShapes()->get_Item(0)->getTextFrame();
    # Auf den Absatz zugreifen
    $para = $tf1->getParagraphs()->get_Item(0);
    # Eigenschaften des Absatzes festlegen
    $para->getParagraphFormat()->setSpaceWithin(80);
    $para->getParagraphFormat()->setSpaceBefore(40);
    $para->getParagraphFormat()->setSpaceAfter(40);
    # Präsentation speichern
    $pres->save("LineSpacing_out.pptx", SaveFormat::Pptx);

  • EffectiveTabs.ExplicitTabCount (2 in our case) property is equal to Tabs.Count.
  • EffectiveTabs collection includes all tabs (from Tabs collection and default tabs).
  • EffectiveTabs.ExplicitTabCount (2 in our case) property is equal to Tabs.Count.
  • EffectiveTabs.DefaultTabSize (294) property shows distance between default tabs (3 and 4 in our example).
  • EffectiveTabs.GetTabByIndex(index) with index = 0 will return first explicit tab (Position = 731), index = 1 - second tab (Position = 1241). If you try to get next tab with index = 2 it will return first default tab (Position = 1470) and etc.
  • EffectiveTabs.GetTabAfterPosition(pos) used for getting next tabulation after some text. For example you have text: “Hello World!”. To render such text you should know where to start draw “world!”. At first, you should calculate length of “Hello” in pixels and call GetTabAfterPosition with this value. You will get next tab position to draw “world!”.

Text mit All‑Caps‑Effekt extrahieren

In PowerPoint, applying the All Caps font effect makes text appear in uppercase on the slide even when it was originally typed in lowercase. When you retrieve such a text portion with Aspose.Slides, the library returns the text exactly as it was entered. To handle this, check TextCapType—if it indicates All, simply convert the returned string to uppercase so that your output matches what users see on the slide.

Let’s say we have the following text box on the first slide of the sample2.pptx file.

The All Caps effect

The code example below shows how to extract the text with the All Caps effect aplyied:

$presentation = new Presentation("sample2.pptx");
try {
    $slide = $presentation->getSlides()->get_Item(0);
    $autoShape = $slide->getShapes()->get_Item(0);
    $paragraph = $autoShape->getTextFrame()->getParagraphs()->get_Item(0);
    $textPortion = $paragraph->getPortions()->get_Item(0);

    echo "Original text: ", $textPortion->getText(), "\n";

    $textFormat = $textPortion->getPortionFormat()->getEffective();
    if (java_values($textFormat->getTextCapType()) === TextCapType::All) {
        $text = $textPortion->getText()->toUpperCase();
        echo "All-Caps effect: ", $text, "\n";
    }
} finally {
    $presentation->dispose();
}

Output:

Ursprünglicher Text: Hello, Aspose!
All-Caps-Effekt: HELLO, ASPOSE!
