Bug 63290

PowerPoint presentation containing one text field containing one paragraph having the issue.

Used PowerPoint presentation, see attachment.
This only contains one text field containing one paragraph having the issue.
Used Code:

import java.awt.Color;
import java.awt.Dimension;
import java.awt.Graphics2D;
import java.awt.geom.Rectangle2D;
import java.awt.image.BufferedImage;
import java.io.FileInputStream;
import java.io.FileOutputStream;
import javax.imageio.ImageIO;
import org.apache.poi.xslf.usermodel.XMLSlideShow;
import org.apache.poi.xslf.usermodel.XSLFSlide;
import java.util.List;
 
public class PptToImageSimplest {
 public static void main(String args[]) throws Exception {
  FileInputStream in =new FileInputStream("PPT.pptx");
  XMLSlideShow ppt = new XMLSlideShow(in);
  //get the dimension of size of the slide
  Dimension pgsize = ppt.getPageSize();
  //get slides
  List<XSLFSlide> slides = ppt.getSlides();
  BufferedImage img = null;
  FileOutputStream out = null;
  for (int i = 0; i < slides.size(); i++) {
   img = new BufferedImage((int)Math.ceil(pgsize.width), (int)Math.ceil(pgsize.height), BufferedImage.TYPE_INT_RGB);
   Graphics2D graphics = img.createGraphics();
   //clear the drawing area
   graphics.setPaint(Color.white);
   graphics.fill(new Rectangle2D.Float(0, 0, pgsize.width, pgsize.height));
   //render
   slides.get(i).draw(graphics);
   //creating an image file as output
   out = new FileOutputStream("ppt_image_" + i + ".png");
   ImageIO.write(img, "png", out);
   out.close();    
  }
 }
}
 

Problem:
Apache POI .draw(graphics) does not draw the first text run in text field properly.
Reason:
The text field contains a paragraph which uses Default Run Properties in  Paragraph Properties. The first text run has no Run Properties of it's own. XML looks like:

<a:p>
 <a:pPr>
  <a:defRPr lang="de-DE" sz="4000" dirty="0" err="1" smtClean="0">
   <a:solidFill>
    <a:srgbClr val="FF0000"/>
   </a:solidFill>
  </a:defRPr>
 </a:pPr>
 <a:r>
  <a:t>DefaultRunProperties </a:t>
 </a:r>
 <a:r>
  <a:rPr lang="de-DE" sz="4000" dirty="0" err="1" smtClean="0">
   <a:solidFill>
    <a:srgbClr val="00FF00"/>
   </a:solidFill>
  </a:rPr>
  <a:t>ExplicitRunProperties</a:t>
 </a:r>
</a:p>

PowerPoint renders it so that first run inherits the defRP. But Apache POI does not.

PPTx To image through Spire java libraries

the same PPTx converted through Spire java libraries is producing the correct output.

applied via r1878492
various fixes to HSLF
moved line spacing to the following line
refactored PropertyFetcher with lambdas

Regarding r1878492, Is there any maven release for this bug fix ?

No ... the next official release (5.0.0) won't be available for the next few weeks, as we work on providing a modular (jigsaw) version. Either you download a nightly and install it (http://maven.apache.org/guides/mini/guide-3rd-party-jars-local.html) or you download the source and call "ant mvn-install"

I tried the 5.0 jars and it resolved the problem(text overlapping) i have reported.

Hi Team, May I know if there is any planned time for Apache POI 5.0 release ?

The 5.0.0 release is due to December '20.
As this was commented as resolved - I'm now closing it.
