Auto Fit Text or Shape in PowerPoint using Java codes

Among free third-party libraries I used, Free Spire.Presentation for Java supports automatically shrinking text to fit a shape or resizing a shape to fit text by setting AutofitType as NORMAL or SHAPE. Today I’ll introduce how to do so using Java codes.

DEPENDENCY

First of all, we need to add a Jar file called Spire.Presentation.jar to IDEA. There are two methods to do it.

Method One: Download the package of the free library from the link, find Spire.Presentation.jar in the “lib” folder and then manually add it to IDEA.

Method Two: Create a Maven project in IDEA, type the following codes in the pom.xml file and finally click the button “import changes”.

USING THE CODE
import com.spire.presentation.*;
import java.awt.geom.Rectangle2D;

public class AutoFitTextOrShape {
    public static void main(String[] args) throws Exception {
        //create a Presentation instance
        Presentation presentation = new Presentation();

        //get the first slide
        ISlide slide = presentation.getSlides().get(0);

        //add a shape to slide
        IAutoShape textShape1 = slide.getShapes().appendShape(ShapeType.RECTANGLE, new Rectangle2D.Float(50,50,200,80));

        //add text to shape
        textShape1.getTextFrame().setText("Your nose,through thick and thin,remains between your eyes and chin,not pasted on some other place,be glad your nose is on your face!");
        //set the auto-fit type to normal, which means the text automatically shrinks to fit the shape when text overflows the shape
        textShape1.getTextFrame().setAutofitType(TextAutofitType.NORMAL);

        //add another shape to slide
        IAutoShape textShape2 = slide.getShapes().appendShape(ShapeType.RECTANGLE, new Rectangle2D.Float(350, 50, 200, 80));
        textShape2.getTextFrame().setText("Be glad your nose in on your face");

        //set the auto-fit type to shape, which means the shape size automatically decreases or increases to fit text
        textShape2.getTextFrame().setAutofitType(TextAutofitType.SHAPE);

        //save to file
        presentation.saveToFile("output/AutoFit.pptx", FileFormat.PPTX_2013);
    }
}
