## Add Watermark to PPT Presentation via Java

Using [Aspose.Slides for Java](/slides/java/), you can add text and image watermarks to PPT presentations. Add a watermark shape to a master slide so the watermark appears on slides that use that master.

### Add Text Watermark to PPT using Java

```java
Presentation presentation = new Presentation("presentation.ppt");
try {
    IMasterSlide masterSlide = presentation.getMasters().get_Item(0);
    IAutoShape watermarkShape = masterSlide.getShapes().addAutoShape(ShapeType.Rectangle, 100, 100, 400, 120);
    ITextFrame watermarkTextFrame = watermarkShape.addTextFrame("Watermark");
    watermarkTextFrame.getParagraphs().get_Item(0).getPortions().get_Item(0).getPortionFormat().setFontHeight(48);

    presentation.save("watermark.ppt", SaveFormat.Ppt);
} finally {
    presentation.dispose();
}
```

### Add Image Watermark to PPT Presentation using Java

```java
Presentation presentation = new Presentation("presentation.ppt");
try {
    byte[] imageData = Files.readAllBytes(Paths.get("watermark.png"));
    IPPImage watermarkImage = presentation.getImages().addImage(imageData);
    IMasterSlide masterSlide = presentation.getMasters().get_Item(0);
    IAutoShape watermarkShape = masterSlide.getShapes().addAutoShape(ShapeType.Rectangle, 100, 100, 300, 200);

    watermarkShape.getFillFormat().setFillType(FillType.Picture);
    watermarkShape.getFillFormat().getPictureFillFormat().getPicture().setImage(watermarkImage);
    watermarkShape.getFillFormat().getPictureFillFormat().setPictureFillMode(PictureFillMode.Stretch);

    presentation.save("image-watermark.ppt", SaveFormat.Ppt);
} finally {
    presentation.dispose();
}
