Font Replacement

Contents
[ ]

If you change your mind about using a font, you can replace that font with another font. All instances of the old font will be replaced by the new font.

Aspose.Slides allows you to replace a font this way:

  1. Load the relevant presentation.
  2. Load the font that will be replaced.
  3. Load the new font.
  4. Replace the font.
  5. Write the modified presentation as a PPTX file.

This C++ code demonstrates font replacement:

// Loads a presentation
auto presentation = System::MakeObject<Presentation>(u"Fonts.pptx");

// Loads the source font that will be replaced
auto sourceFont = System::MakeObject<FontData>(u"Arial");

// Loads the new font
auto destFont = System::MakeObject<FontData>(u"Times New Roman");

// Replaces the fonts
presentation->get_FontsManager()->ReplaceFont(sourceFont, destFont);

// Saves the presentation
presentation->Save(u"UpdatedFont_out.pptx", SaveFormat::Pptx);
