Getting unwanted TextFragment

Aspose.PDF Product Family
#1

Dear All,


Here is the code for adding “Table Of Contents” as new TextFragment, where ‘finalPDF’ is the pdf Document.
Page tocPage = finalPDF.getPages().insert(1);
TocInfo tocInfo = new TocInfo();
TextFragment title = new TextFragment(“Table Of Contents”);
title.getTextState().setFontSize(20);
title.getTextState().setFontStyle(FontStyles.Bold);
tocInfo.setTitle(title);
tocPage.setTocInfo(tocInfo);

This code works fine while saving it to the local path. But it generates “Table Of Contents” twice while writing document ByteArrayOutputStream and saving from the same ByteArrayInputStream.

Please Note contents are fine in attached file, only extra “Table Of Contents” at the bottom is headache.

Regards.

Hi there,


Thanks for your inquriy. I have tested the scenario using following code with Aspose.Pdf for Java 17.2.0 and unable to notice the reported issue, duplication of TextFragment. We will appreciate it if you please share some more details, your complete code and Aspose.Pdf for Java version, so we will further investigate the issue.

//Load an existing PDF files<o:p></o:p>

com.aspose.pdf.Document doc = new com.aspose.pdf.Document(myDir+"input.pdf");

//Get access to first page of PDF file

com.aspose.pdf.Page tocPage = doc.getPages().insert(1);

//Create object to represent TOC information

com.aspose.pdf.TocInfo tocInfo = new com.aspose.pdf.TocInfo();

com.aspose.pdf.TextFragment title = new com.aspose.pdf.TextFragment("Table Of Contents");

title.getTextState().setFontSize(20);

title.getTextState().setFontStyle(com.aspose.pdf.FontStyles.Bold);

//Set the title for TOC

tocInfo.setTitle(title);

tocPage.setTocInfo(tocInfo);

//Create string objects which will be used as TOC elements

String[] titles = new String[4];

titles[0] = "First page";

titles[1] = "Second page";

titles[2] = "Third page";

titles[3] = "Fourth page";

for (int i = 0; i < 4; i++) {

// Create Heading object

com.aspose.pdf.Heading heading2 = new com.aspose.pdf.Heading(1);

com.aspose.pdf.TextSegment segment2 = new com.aspose.pdf.TextSegment();

heading2.setTocPage(tocPage);

heading2.getSegments().add(segment2);

// Specify the destination page for heading object

heading2.setDestinationPage(doc.getPages().get_Item(i + 2));

// Destination page

heading2.setTop(doc.getPages().get_Item(i + 2).getRect().getHeight());

// Destination coordinate

segment2.setText(titles[i]);

// Add heading to page containing TOC

tocPage.getParagraphs().add(heading2);

}

ByteArrayOutputStream output = new ByteArrayOutputStream();

doc.save(output);

doc= new Document(new ByteArrayInputStream(output.toByteArray()));

//Save the updated document

doc.save(myDir+"TOC_Output_Java.pdf");

Thanks for the code and precise definition.
