Strange beahviour with paragraphs (PPTX)

Hello,

I have a string containing newlines (\n) and the following code:

String text = "abc\ndef\nghi\njkl";
TextFrame tf = ( (AutoShapeEx) slide.findShapeByAltText(altText)).getTextFrame();
tf.setText(text);

System.out.println(tf.getParagraphs().size());

No matter how many \n's are in the string - what I get is always exactly two paragraphs; one containing all of the string up to the last \n (in the above example: "abc\ndef\nghi"), and one containing the rest ("jkl").

However I would expect either that each substring (abc, def, ghi, jkl) will get its own paragraph, or that the whole string is added to one single paragraph.

What I need is to have each substring in its own paragraph, so that I can decide whether it gets a bullet point or not, e.g.

* abc
def
gji
* jkl

I managed to do it by setting each substring in a new paragraph using tf.getParagraphs().add(newParagraph). However the behaviour described above seems very strange to me so I wanted to report it.

Kind regards
Stefan

Hi Stefan,

Thanks for you inquiry.

I have used the following code snippet and able to resolve the issue which you were facing.
Note: I am using latest version of Aspose.Slides for Java which can be found here.

   public static void para(){
         try{
               //Instantiate a PresentationEx class that represents a PPTX file
               PresentationEx pres = new PresentationEx();

               //Accessing first slide
               SlideEx slide = pres.getSlides().get(0);

               //Add an AutoShape of Rectangle type
               int idx = slide.getShapes().addAutoShape(ShapeTypeEx.RECTANGLE, 50, 150, 300, 150);
               AutoShapeEx ashp = (AutoShapeEx)slide.getShapes().get(idx);
               //Access TextFrame of the AutoShape
               String text = "abc\ndef\nghi\njkl";
               TextFrameEx tf = ashp.getTextFrame();
               tf.setText(text);
               //Write PPTX to Disk                pres.write("D:\\Assignments\\Aspose.Slides\\Java\\Queries\\ParaTest.pptx");          }catch (IOException e) {                // TODO Auto-generated catch block                e.printStackTrace();          }    }

Many Thanks.

Best Regards
