Manage Text Portions in Presentations Using C++

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:

auto presentation = System::MakeObject<Presentation>(u"Shapes.pptx");
auto shape = System::ExplicitCast<IAutoShape>(presentation->get_Slides()->idx_get(0)->get_Shapes()->idx_get(0));
auto textFrame = shape->get_TextFrame();

for (const auto& paragraph : textFrame->get_Paragraphs())
{
    for (const auto& portion : paragraph->get_Portions())
    {
        PointF point = portion->GetCoordinates();
        Console::WriteLine(String(u"Coordinates X =") + point.get_X() + u" Coordinates Y =" + point.get_Y());
    }
}

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.
