Text Formatting

Highlight Text

Method highlightText has been added to ITextFrame interface and TextFrame class.

It allows to highlight text part with background color using text sample, similar to Text Highlight Color tool in PowerPoint 2019.

The code snippet below shows how to use this feature:

  $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);// highlighting all words 'important'

    $pres->getSlides()->get_Item(0)->getShapes()->get_Item(0)->getTextFrame()->highlightText("to", java("java.awt.Color")->MAGENTA, $textHighlightingOptions);// highlighting all separate 'the' occurrences

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

Highlight Text using Regular Expression

Method highlightRegex has been added to ITextFrame interface and TextFrame class.

It allows to highlight text part with background color using regex, similar to Text Highlight Color tool in PowerPoint 2019.

The code snippet below shows how to use this feature:

  $pres = new Presentation("Presentation.pptx");
  try {
    $options = new TextHighlightingOptions();
    $pres->getSlides()->get_Item(0)->getShapes()->get_Item(0)->getTextFrame()->highlightRegex("\\b[^\\s]{4}\\b", java("java.awt.Color")->YELLOW, $options);// highlighting all words with 10 symbols or longer

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

Set Text Background Color

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)));
    $presentation->save("text-red.pptx", SaveFormat::Pptx);
  } finally {
    if (!java_is_null($presentation)) {
      $presentation->dispose();
    }
  }

This PHP code shows you how to set the background color for only a portion of a 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);
    $redPortion = StreamSupport->stream($autoShape->getTextFrame()->getParagraphs()->get_Item(0)->getPortions()->spliterator(), false)->filter(( p) -> $p->getText()->contains("Red"))->findFirst();
    if ($redPortion->isPresent()) {
      $redPortion->get()->getPortionFormat()->getHighlightColor()->setColor(java("java.awt.Color")->RED);
    }
    $presentation->save("text-red.pptx", SaveFormat::Pptx);
  } finally {
    if (!java_is_null($presentation)) {
      $presentation->dispose();
    }
  }

Align Text Paragraphs

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.

  # Instantiate a Presentation object that represents a PPTX file
  $pres = new Presentation("ParagraphsAlignment.pptx");
  try {
    # Accessing first slide
    $slide = $pres->getSlides()->get_Item(0);
    # Accessing the first and second placeholder in the slide and typecasting it as AutoShape
    $tf1 = $slide->getShapes()->get_Item(0)->getTextFrame();
    $tf2 = $slide->getShapes()->get_Item(1)->getTextFrame();
    # Change the text in both placeholders
    $tf1->setText("Center Align by Aspose");
    $tf2->setText("Center Align by Aspose");
    # Getting the first paragraph of the placeholders
    $para1 = $tf1->getParagraphs()->get_Item(0);
    $para2 = $tf2->getParagraphs()->get_Item(0);
    # Aligning the text paragraph to center
    $para1->getParagraphFormat()->setAlignment(TextAlignment->Center);
    $para2->getParagraphFormat()->setAlignment(TextAlignment->Center);
    # Writing the presentation as a PPTX file
    $pres->save("Centeralign_out.pptx", SaveFormat::Pptx);
  } finally {
    if (!java_is_null($pres)) {
      $pres->dispose();
    }
  }

Set Transparency for Text

This article demonstrates how to set transparency property to any text shape using Aspose.Slides for PHP via Java. In order to set the transparency to text. Please follow the steps below:

  1. Create an instance of Presentation class.
  2. Get the reference of a slide.
  3. Set shadow color
  4. Write the presentation as a PPTX file.

The implementation of the above steps is given below.

  $pres = new Presentation("transparency.pptx");
  try {
    $shape = $pres->getSlides()->get_Item(0)->getShapes()->get_Item(0);
    $effects = $shape->getTextFrame()->getParagraphs()->get_Item(0)->getPortions()->get_Item(0)->getPortionFormat()->getEffectFormat();
    $outerShadowEffect = $effects->getOuterShadowEffect();
    $shadowColor = $outerShadowEffect->getShadowColor()->getColor();
    echo($shadowColor->toString() . " - transparency is: " . $shadowColor->getAlpha() / 255.0 * 100);
    # set transparency to zero percent
    $outerShadowEffect->getShadowColor()->setColor(new java("java.awt.Color", $shadowColor->getRed(), $shadowColor->getGreen(), $shadowColor->getBlue(), 255));
    $pres->save("transparency-2.pptx", SaveFormat::Pptx);
  } finally {
    if (!java_is_null($pres)) {
      $pres->dispose();
    }
  }

Set Character Spacing for Text

Aspose.Slides allows you to set the space between letters in a textbox. This way, you get to adjust the visual density of a line or block of text by expanding or condensing the spacing between characters.

This PHP code shows you how to expand the spacing for one line of text and condense the spacing for another line:

  $presentation = new Presentation("in.pptx");
  $textBox1 = $presentation->getSlides()->get_Item(0)->getShapes()->get_Item(0);
  $textBox2 = $presentation->getSlides()->get_Item(0)->getShapes()->get_Item(1);
  $textBox1->getTextFrame()->getParagraphs()->get_Item(0)->getParagraphFormat()->getDefaultPortionFormat()->setSpacing(20);// expand

  $textBox2->getTextFrame()->getParagraphs()->get_Item(0)->getParagraphFormat()->getDefaultPortionFormat()->setSpacing(-2);// condense

  $presentation->save("out.pptx", SaveFormat::Pptx);

Manage Paragraph’s Font Properties

Presentations usually contain both text and images. The text can be formatted in a various ways, either to highlight specific sections and words, or to conform with corporate styles. Text formatting helps users vary the look and feel of the presentation content. This article shows how to use Aspose.Slides for PHP via Java to configure the font properties of paragraphs of text on slides.

    # Accessing the first Paragraph
    $para1 = $tf1->getParagraphs()->get_Item(0);
    $para2 = $tf2->getParagraphs()->get_Item(0);
    # Accessing the first portion
    $port1 = $para1->getPortions()->get_Item(0);
    $port2 = $para2->getPortions()->get_Item(0);
    # Define new fonts
    $fd1 = new FontData("Elephant");
    $fd2 = new FontData("Castellar");
    # Assign new fonts to portion
    $port1->getPortionFormat()->setLatinFont($fd1);
    $port2->getPortionFormat()->setLatinFont($fd2);

    # Add TextFrame to the Rectangle
    $ashp->addTextFrame("");
    $ashp->getFillFormat()->setFillType(FillType::NoFill);
    # Accessing the text frame
    $txtFrame = $ashp->getTextFrame();
    $txtFrame->getTextFrameFormat()->setTextVerticalType(TextVerticalType::Vertical270);
    # Create the Paragraph object for text frame
    $para = $txtFrame->getParagraphs()->get_Item(0);
    # Create Portion object for paragraph
    $portion = $para->getPortions()->get_Item(0);
    $portion->setText("A quick brown fox jumps over the lazy dog. A quick brown fox jumps over the lazy dog.");
    $portion->getPortionFormat()->getFillFormat()->setFillType(FillType::Solid);

Set Custom Rotation Angle for TextFrame

Aspose.Slides for PHP via Java now supports, Setting custom rotation angle for textframe. In this topic, we will see with example how to set the RotationAngle property in Aspose.Slides. The new methods setRotationAngle and getRotationAngle have been added to IChartTextBlockFormat and ITextFrameFormat interfaces, allows to set the custom rotation angle for textframe. In order to set the RotationAngle, Please follow the steps below:

  1. Create an instance of Presentation class.
  2. Add a chart on slide.
  3. Set RotationAngle property.
  4. Write the presentation as a PPTX file.

In the example given below, we set the RotationAngle property.

  # Create an instance of Presentation class
  $pres = new Presentation();
  try {
    # Get the first slide
    $slide = $pres->getSlides()->get_Item(0);
    # Add an AutoShape of Rectangle type
    $ashp = $slide->getShapes()->addAutoShape(ShapeType::Rectangle, 150, 75, 350, 350);
    # Add TextFrame to the Rectangle
    $ashp->addTextFrame("");
    $ashp->getFillFormat()->setFillType(FillType::NoFill);
    # Accessing the text frame
    $txtFrame = $ashp->getTextFrame();
    $txtFrame->getTextFrameFormat()->setRotationAngle(25);
    # Create the Paragraph object for text frame
    $para = $txtFrame->getParagraphs()->get_Item(0);
    # Create Portion object for paragraph
    $portion = $para->getPortions()->get_Item(0);

  } finally {
    if (!java_is_null($pres)) {
      $pres->dispose();
    }
  }

Line Spacing of Paragraph

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:

  # Create an instance of Presentation class
  $pres = new Presentation("Fonts.pptx");
  try {
    # Obtain a slide's reference by its index
    $sld = $pres->getSlides()->get_Item(0);
    # Access the TextFrame
    $tf1 = $sld->getShapes()->get_Item(0)->getTextFrame();
    # Access the Paragraph
    $para = $tf1->getParagraphs()->get_Item(0);
    # Set properties of Paragraph
    $para->getParagraphFormat()->setSpaceWithin(80);
    $para->getParagraphFormat()->setSpaceBefore(40);
    $para->getParagraphFormat()->setSpaceAfter(40);
    # Save Presentation
    $pres->save("LineSpacing_out.pptx", SaveFormat::Pptx);
  } finally {
    if (!java_is_null($pres)) {
      $pres->dispose();
    }
  }

Set the AutofitType Property for TextFrame

In this topic, we will explore the different formatting properties of text frame. This article covers how to Set the AutofitType property of text frame, anchor of text and rotating the text in presentation. Aspose.Slides for PHP via Java allows developers to set AutofitType property of any text frame. AutofitType could be set to Normal or Shape. If set to Normal then shape will remain the same whereas the text will be adjusted without causing the shape to change itself whereas If AutofitType is set to Shape, then shape will be modified such that only required text is contained in it. To set the AutofitType property of a text frame, please follow the steps below:

  1. Create an instance of Presentation class.
  2. Access the first slide.
  3. Add any shape to the slide.
  4. Access the ITextFrame.
  5. Set the AutofitType of the TextFrame.
  6. Save file to disk.
  # Create an instance of Presentation class
  $pres = new Presentation();
  try {
    # Access the first slide
    $slide = $pres->getSlides()->get_Item(0);
    # Add an AutoShape of Rectangle type
    $ashp = $slide->getShapes()->addAutoShape(ShapeType::Rectangle, 150, 75, 350, 150);
    # Add TextFrame to the Rectangle
    $ashp->addTextFrame("");
    $ashp->getFillFormat()->setFillType(FillType::NoFill);
    # Accessing the text frame
    $txtFrame = $ashp->getTextFrame();
    $txtFrame->getTextFrameFormat()->setAutofitType(TextAutofitType::Shape);
    # Create the Paragraph object for text frame
    $para = $txtFrame->getParagraphs()->get_Item(0);
    # Create Portion object for paragraph
    $portion = $para->getPortions()->get_Item(0);
    $portion->setText("A quick brown fox jumps over the lazy dog. A quick brown fox jumps over the lazy dog.");
    $portion->getPortionFormat()->getFillFormat()->setFillType(FillType::Solid);
    $portion->getPortionFormat()->getFillFormat()->getSolidFillColor()->setColor(java("java.awt.Color")->BLACK);
    # Save Presentation
    $pres->save($resourcesOutputPath . "formatText_out.pptx", SaveFormat::Pptx);
  } finally {
    if (!java_is_null($pres)) {
      $pres->dispose();
    }
  }

Set Anchor of TextFrame

Aspose.Slides for PHP via Java allows developers to Anchor of any TextFrame. TextAnchorType specifies that where is that text placed in the shape. AnchorType could be set to Top, Center, Bottom, Justified or Distributed. To set Anchor of any TextFrame, please follow the steps below:

  1. Create an instance of Presentation class.
  2. Access the first slide.
  3. Add any shape to the slide.
  4. Access the ITextFrame.
  5. Set TextAnchorType of the TextFrame.
  6. Save file to disk.
  # Create an instance of Presentation class
  $pres = new Presentation();
  try {
    # Get the first slide
    $slide = $pres->getSlides()->get_Item(0);
    # Add an AutoShape of Rectangle type
    $ashp = $slide->getShapes()->addAutoShape(ShapeType::Rectangle, 150, 75, 350, 350);
    # Add TextFrame to the Rectangle
    $ashp->addTextFrame("");
    $ashp->getFillFormat()->setFillType(FillType::NoFill);
    # Accessing the text frame
    $txtFrame = $ashp->getTextFrame();
    $txtFrame->getTextFrameFormat()->setAnchoringType(TextAnchorType::Bottom);
    # Create the Paragraph object for text frame
    $para = $txtFrame->getParagraphs()->get_Item(0);
    # Create Portion object for paragraph
    $portion = $para->getPortions()->get_Item(0);
    $portion->setText("A quick brown fox jumps over the lazy dog. A quick brown fox jumps over the lazy dog.");
    $portion->getPortionFormat()->getFillFormat()->setFillType(FillType::Solid);
    $portion->getPortionFormat()->getFillFormat()->getSolidFillColor()->setColor(java("java.awt.Color")->BLACK);
    # Save Presentation
    $pres->save("AnchorText_out.pptx", SaveFormat::Pptx);
  } finally {
    if (!java_is_null($pres)) {
      $pres->dispose();
    }
  }

Tabs and EffectiveTabs in Presentation

All text tabulations are given in pixels.

todo:image_alt_text
Figure: 2 Explicit Tabs and 2 Default Tabs
  • 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!”.
