Hi support,

I’m creating headings and then I’m trying to get the label, but I get “null”, although I see in the output the labels : 1.1 ; 3.2.2 etc.

Please advice,
Milan

Hi shahzad.latif,

Here is a code that prints null strings instead of :“1”, “1.1”, “1.1.1” etc. :

Pdf pdf1 = new Pdf();
Section sec1 = pdf1.getSections().add();

for(int i=1; i < 10 ; ++i)
{
Heading heading1 = new Heading(pdf1,sec1, i);
heading1.getSegments().add(“Heading_” + i);
heading1.setLabelWidth(i*10);
sec1.getParagraphs().add(heading1);
System.out.println(heading1.getUserLabel());
}

FileOutputStream out = new FileOutputStream(new File(“C:/Temp/HeadingNumbering.pdf”));
pdf1.save(out);

Regards,
Milan

Hi Milan,

I wonder why you're using System.out.println in the code to show the label. I would rather suggest to change the code like below in blue:

Pdf pdf1 = new Pdf();
Section sec1 = pdf1.getSections().add();

for(int i=1; i < 10 ; ++i)
{
Heading heading1 = new Heading(pdf1,sec1, i);
heading1.getSegments().add("Heading_" + i);
heading1.setLabelWidth(i*10);

heading1.setIsAutoSequence(true);

heading1.setLevel(i);

sec1.getParagraphs().add(heading1);
}

FileOutputStream out = new FileOutputStream(new File("C:/Temp/HeadingNumbering.pdf"));
pdf1.save(out);

Hi,

I’m using System.out.println to show you that although the label for heading is set, I cannot get it. I want to write that label in some other section in my pdf document. Use this line "sec1.getParagraphs().add(new Text(sec1, “Label = " + heading1.getUserLabel()));” instead of the one with System.out.println, and you’ll note what I’m pointing to.

Thanks for looking into this,
Milan

Hi milan,

The method Heading.getUserLabel() can only retrieve the value you set through the method: Heading.setUserLabel(String). As you have not called Heading.setUserLabel(String), it’s not strange you get a “null”.

You cannot get the Heading label when it is generated automatically. Maybe we will provide this function in the future release.

Thank you for using our product.
