Manage Text Portions in Presentations Using Java

Get Coordinates of a Text Portion

getCoordinates() method has been added to IPortion and Portion class which allows retrieving the coordinates of the beginning of the portion.

// Instantiate Prseetation class that represents the PPTX
Presentation pres = new Presentation();
try {
    // Reshaping the context of presentation
    IAutoShape shape = (IAutoShape) pres.getSlides().get_Item(0).getShapes().get_Item(0);
    
    ITextFrame textFrame = (ITextFrame) shape.getTextFrame();
    
    for (IParagraph paragraph : textFrame.getParagraphs()) 
    {
        for (IPortion portion : paragraph.getPortions()) 
        {
            Point2D.Float point = portion.getCoordinates();
            System.out.println("X: " + point.x + " Y: " + point.y);
        }
    }
} finally {
    if (pres != null) pres.dispose();
}

FAQ

Can I apply a hyperlink to only part of the text within a single paragraph?

Yes, you can assign a hyperlink to an individual portion; only that fragment will be clickable, not the entire paragraph.

How does style inheritance work: what does a Portion override, and what is taken from Paragraph/TextFrame?

Portion-level properties have the highest precedence. If a property is not set on the Portion, the engine takes it from the Paragraph; if it is not set there either, from the TextFrame or the theme style.

What happens if the font specified for a Portion is missing on the target machine/server?

Font substitution rules apply. The text may reflow: metrics, hyphenation, and width can change, which matters for precise positioning.

Can I set a Portion-specific text fill transparency or gradient independent of the rest of the paragraph?

Yes, text color, fill, and transparency at the Portion level can differ from neighboring fragments.
