Font Replacement - PowerPoint C# API

[ ]

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
Presentation presentation = new Presentation("Fonts.pptx");

// Loads the source font that will be replaced
IFontData sourceFont = new FontData("Arial");

// Loads the new font
IFontData destFont = new FontData("Times New Roman");

// Replaces the fonts
presentation.FontsManager.ReplaceFont(sourceFont, destFont);

// Saves the presentation
presentation.Save("UpdatedFont_out.pptx", SaveFormat.Pptx);
