Apache POI Page Size

We can get and set page size of the powerpoint page. To get the page size getPageSize() method is used whereas to set the size setPageSize() method is used.

The retrieved page size returns coordinates that are expressed in points. Lets see an example.

Apache POI Page Size Example

package poiexample;
import java.io.FileInputStream;
import org.apache.poi.xslf.usermodel.XMLSlideShow;
public class SlideSizeExample {
	public static void main(String[] args) {
		try(XMLSlideShow ppt = new XMLSlideShow(new FileInputStream("Javatpoint.pptx"))){
		    java.awt.Dimension pgsize = ppt.getPageSize();
		    int width = pgsize.width;  //slide width in points
		    int height = pgsize.height; //slide height in points
		    System.out.println("width: "+  width);
		    System.out.println("height: "+ height);
		}catch(Exception e) {
			 System.out.println(e);
		 }
	}
}

Output:

width: 720
height: 540

Lets see an example, to set page size.

Apache POI Setting Page Size Example

package poiexample;
import java.io.FileInputStream;
import org.apache.poi.xslf.usermodel.XMLSlideShow;
public class SlideSizeExample {
	public static void main(String[] args) {
		try(XMLSlideShow ppt = new XMLSlideShow(new FileInputStream("Javatpoint.pptx"))){
		    java.awt.Dimension pgsize = ppt.getPageSize();
		    int width  = pgsize.width;  //slide width in points
		    int height = pgsize.height; //slide height in points
		    System.out.println("width: "+  width);
		    System.out.println("height: "+ height);
		    ppt.setPageSize(new java.awt.Dimension(1024, 768));
		    java.awt.Dimension newpgsize = ppt.getPageSize();
		    System.out.println("\nSlide size after setting new size.");
		    System.out.println("width: "+  newpgsize.width);
		    System.out.println("height: "+ newpgsize.height);
		}catch(Exception e) {
			 System.out.println(e);
		 }
	}
}

Output:
