String dataDir = "Your Document Directory";

Step 2: Load Presentation

Load the PowerPoint presentation using Aspose.Slides’ Presentation class.

Presentation pres = new Presentation(dataDir + "PresFontsSubst.pptx");

Step 3: Perform Font Substitution

Iterate through the font substitutions present in the presentation and print the original font names along with their substituted counterparts.

for (FontSubstitutionInfo fontSubstitution : pres.getFontsManager().getSubstitutions()) {
    System.out.println(fontSubstitution.getOriginalFontName() + " -> " + fontSubstitution.getSubstitutedFontName());
}

Step 4: Dispose Presentation Object

Dispose of the presentation object to release the resources.

if (pres != null) pres.dispose();
