Presentation Localization

Change Language for Presentation and Shape’s Text

• Create an instance of Presentation class.
• Obtain the reference of a slide by using its Index.
• Add an IAutoShape of Rectangle type to the slide.
• Add some text to the TextFrame.
• Setting Language Id to text.
• Write the presentation as a PPTX file.

The implementation of the above steps is demonstrated below in an example.

Presentation pres = new Presentation("test.pptx");
try {
    IAutoShape shape = pres.getSlides().get_Item(0).getShapes().addAutoShape(ShapeType.Rectangle, 50, 50, 200, 50);
    shape.addTextFrame("Text to apply spellcheck language");

    shape.getTextFrame().getParagraphs().get_Item(0).getPortions().get_Item(0).getPortionFormat().setLanguageId("en-EN");

    pres.save("output.pptx", SaveFormat.Pptx);
} finally {
    if (pres != null) pres.dispose();
}
