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(“tutoraspire.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
