IsAutoSequence limited to 3 level?

Aspose.PDF Product Family
1

I turned around an "index out of range" error while generating a pdf from a xml for a couple of day.

the number of level seem to be limited to 3 ?? Generating a TOC for a document fails when more than

3 chapter level exist: 1. 1.1. 1.1.1 and 1.1.1.1

Is there a hidden parameter somewhere you could change? I need to generate document with one main chapter and up to 8 sub chapters !?

1. main (level1)

1.1 sub (level2)

1.2. sub (level2)

1.2.1 sub (level3)

1.2.1.1 sub (level4)

1.2.1.1.1 etc.

Hi,


Well, I checked your scenario with the Aspose.Pdf for .NET v6.7 and there is no restriction on levels of TOC. Following is the sample code I used to add up to 5 levels in a TOC.


//Create a section in the Pdf document

Aspose.Pdf.Generator.Pdf pdf1 = new Pdf();

Aspose.Pdf.Generator.Section sec1 = pdf1.Sections.Add();

for (int Level = 1; Level != 6; Level++)

{

Aspose.Pdf.Generator.Heading heading2 = new Aspose.Pdf.Generator.Heading(pdf1, sec1, Level);

Aspose.Pdf.Generator.Segment segment2 = new Aspose.Pdf.Generator.Segment(heading2);

heading2.Segments.Add(segment2);

heading2.IsAutoSequence = true;

segment2.Content = "this is heading of level ";

segment2.Content += Level.ToString();

//Add the heading into Table Of Contents.

heading2.IsInList = true;

sec1.Paragraphs.Add(heading2);

}

pdf1.Save("E:\\AP Data\\March2012\\TOC.Pdf");


Please share your sample code and template file (if any) to show us the issue. We will check it and get back to you soon.

Sorry for the inconvenience,

Hi Nausherwan,

your code works, I can confirm this. The problem appear when a toc is added.

Here is the snippet:

Aspose.Pdf.Generator.Pdf pdf1 = new Pdf();

pdf1.BookmarkLevel = 6;

ListSection TOCSection1 = new ListSection(pdf1);

TOCSection.ListType = ListType.TableOfContents;

Text SText1 = new Text("Table Of Content1");

TOCSection1.Title = SText1;

TOCSection1.Title.TextInfo.Alignment = AlignmentType.Center;

TOCSection1.Title.TextInfo.FontSize = 20;

pdf1.Sections.Add(TOCSection1); //without this line all everything is ok ...

Aspose.Pdf.Generator.Section sec1 = pdf1.Sections.Add();

//error ifmax >4!!!!

int max=5;

for (int Level = 1; Level != max; Level++) {

Aspose.Pdf.Generator.Heading heading2 = new Aspose.Pdf.Generator.Heading(pdf1, sec1, Level); Aspose.Pdf.Generator.Segment segment2 = new Aspose.Pdf.Generator.Segment(heading2);

heading2.Segments.Add(segment2);

heading2.IsAutoSequence = true;

segment2.Content = "this is heading of level ";

segment2.Content += Level.ToString();

//Add the heading into Table Of Contents.

heading2.IsInList = true; sec1.Paragraphs.Add(heading2);

}

pdf1.Save(Server.MapPath("~//temp//") + "TOC.Pdf");

Any idea ?

Best regards

yesterday we updated our aspose for pdf from V 6.7 to 7.4
the creation of TOC for pdf having chapters with more than 3 level is still not resolved
here is the code:

_pdf = new Pdf();
_pdf.IsBookmarked = true;
_pdf.BookmarkLevel = 10;
ListSection TOCSection = new ListSection(_pdf);
TOCSection.ListType = ListType.TableOfContents;
_pdf.Sections.Add(TOCSection);

if we omit the toc creation reduce the level to less than 3 everything is
fine, otherwise we get still the “index of of range error” on saving the generated pdf

any idea?

Sorry for a delay in response.

I am afraid the issue is not resolved yet regarding creation of TOC in a PDF file. I have asked the development team to share an ETA regarding the resolution of the issue. As soon as I get a feedback, I will update you via this forum thread.

Hi Nausherwan,

just check out the follwing snipped:

public void CreateTestTOC()
{
_pdf = new Pdf();
_pdf.IsBookmarked = true; // im viewer inhaltsverzeichnis mit hyperlink anzeigen
_pdf.BookmarkLevel = 10; //anzahl ebenen die bei den BookmarkLevel angezeigt werden

ListSection TOCSection = new ListSection(_pdf);
TOCSection.ListType = ListType.TableOfContents;

Text SText = new Text(“Table Of Content”);

TOCSection.Title = SText;
TOCSection.Title.TextInfo.Alignment = AlignmentType.Center;
TOCSection.Title.TextInfo.FontSize = 20;

//test
_pdf.Sections.Add(TOCSection);

_section = _pdf.Sections.Add();

CreateChapter(“level1”, 1);
CreateChapter(“level2”, 2);
CreateChapter(“level1”, 1);
CreateChapter(“level2”, 2);
CreateChapter(“level2”, 2);
CreateChapter(“level3”, 3);
// CreateChapter(“level4”, 4); //index out of range

CreateParagraph(“ein eintrag”);

_pdf.Save(“TOC.pdf”);

System.Diagnostics.Process.Start(“TOC.pdf”);
}

As soon as you uncomment the line CreateChapter(“level4”, 4);
the index out of range error should appear, at least on my PC
