Text Replacement and Table Formatting in Aspose PDF for Java

Aspose.PDF Product Family

Hello Team,

I recently started working with Aspose PDF for Java to perform Text Replacement that should automatically re-arrange page contents. However, I am encountering issues when dealing with tables:

  1. When I use ReplaceAdjustment as WholeWordsHyphenation, the table lines disappear, as shown in the attached image.
textFragmentAbsorber.getTextReplaceOptions().setReplaceAdjustmentAction(TextReplaceOptions.ReplaceAdjustment.WholeWordsHyphenation);

  1. When I do not use ReplaceAdjustment or if I use ReplaceAdjustment as None, the lines are present, but the contents are not rearranged properly. Specifically, the columns in the table do not adjust correctly if I replace a large text.
textFragmentAbsorber.getTextReplaceOptions().setReplaceAdjustmentAction(TextReplaceOptions.ReplaceAdjustment.None);

The original PDF file looks like this.

Here is the relevant code snippet:

Document document = new Document(Files.newInputStream(Paths.get(SOURCE_PDF_FILE)));
PageCollection pages = document.getPages();

TextFragmentAbsorber textFragmentAbsorber = new TextFragmentAbsorber("Lorem Ipsum is");
TextSearchOptions textSearchOptions = new TextSearchOptions(true);
textFragmentAbsorber.setTextSearchOptions(textSearchOptions);
textFragmentAbsorber.getTextReplaceOptions().setReplaceAdjustmentAction(TextReplaceOptions.ReplaceAdjustment.WholeWordsHyphenation);

document.getPages().accept(textFragmentAbsorber);

TextFragmentCollection textFragmentCollection = textFragmentAbsorber.getTextFragments();

for (TextFragment textFragment : textFragmentCollection) {
    textFragment.setText("Lorem Ipsum is simply dummy text of the printing and typesetting industry.");
}

document.save(Files.newOutputStream(Paths.get(DEST_PDF_FILE)));

Is this a known limitation with tables, or is there a way to achieve the desired behaviour where the table lines are also adjusted, and the content is rearranged correctly?

I am using Aspose PDF with Java 8.

Thank you for your assistance. Regards.

The re-arranging of the content inside PDF after text replacement can be challenging as elements are stored differently in PDF structure. Nevertheless, we can perform investigation to check and find possible solution to deal with such scenarios. Can you please share a sample PDF for our reference?
