Work with PowerPoint Shapes in Java

add-shape.java

// Instantiate Presentation class that represents the PPTX
Presentation pres = new Presentation();

// Get the first slide
ISlide sld = pres.getSlides().get_Item(0);

// Add AutoShape of ellipse type
sld.getShapes().addAutoShape(ShapeType.Ellipse, 100, 150, 150, 100);

// Write the PPTX file to disk
pres.save("add_shape.pptx", SaveFormat.Pptx);

clone-shape.java

// Instantiate Presentation class that represents the PPTX
Presentation pres = new Presentation();

// Get the first slide
ISlide sld = pres.getSlides().get_Item(0);

// Add AutoShape of rectangle type
IShape shp = sld.getShapes().addAutoShape(ShapeType.Rectangle, 50, 150, 75, 150);

// Rotate the shape to 90 degree
shp.setRotation(90);

// Write the PPTX file to disk
pres.save("clone_shape.pptx", SaveFormat.Pptx);

connect-shape.java

// Instantiate Presentation class that represents the PPTX file
Presentation input = new Presentation();

// Access shapes collection for selected slide
IShapeCollection shapes = input.getSlides().get_Item(0).getShapes();

// Add Autoshape Ellipse
IAutoShape ellipse = shapes.addAutoShape(ShapeType.Ellipse, 0, 100, 100, 100);

// Add Autoshape Rectangle
IAutoShape rectangle = shapes.addAutoShape(ShapeType.Rectangle, 100, 300, 100, 100);

// Add connector shape to slide shape collection
IConnector connector = shapes.addConnector(ShapeType.BentConnector2, 0, 0, 10, 10);

// Join Shapes to connectors
connector.setStartShapeConnectedTo(ellipse);
connector.setEndShapeConnectedTo(rectangle);
connector.reroute();

// Save Presentation
input.save("connect_shape.pptx", SaveFormat.Pptx);

remove-shape.java

// Load presentation
Presentation presentation1 = new Presentation("clone_shape.pptx");

// Get slide
ISlide slide = presentation1.getSlides().get_Item(0);

// Shape text to find the shape
String alttext = "User Defined";

// Get number of shapes
int iCount = slide.getShapes().size();

// Loop through shapes
for (int i = 0; i < iCount; i++) {
	
	// Get shape
	IAutoShape ashp = (IAutoShape) slide.getShapes().get_Item(0);
	if (ashp.getAlternativeText().compareTo(alttext) == 0) {    
		// Remove shape
		slide.getShapes().remove(ashp);
	}
}
presentation1.save("remove_shape.pptx", SaveFormat.Pptx);
