Font Replacement

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 Python code demonstrates font replacement:

import aspose.pydrawing as draw
import aspose.slides as slides

# Loads a presentation
with slides.Presentation(path + "Fonts.pptx") as presentation:
    # Loads the source font that will be replaced
    sourceFont = slides.FontData("Arial")

    # Loads the new font
    destFont = slides.FontData("Times New Roman")

    # Replaces the fonts
    presentation.fonts_manager.replace_font(sourceFont, destFont)

    # Saves the presentation
    presentation.save("UpdatedFont_out.pptx", slides.export.SaveFormat.PPTX)
