I am opening up an existing PDF document and replacing token text with database driven values. Everything is working except the formatting of the text is not being preserved. For example if the text is bold and I replace it the bold is lost. Throughout the document there are different fonts and weights so I don’t know at runtime what the style should be but would like it to just remain however it was and just replace the text. Here is the method I’ve got that does the actual replacement.
Should I be doing something more?
I pass in the PDF document I’m working with, the text I want to replace and the new text…
public static void replaceText(Document document, string findText, string replaceText)
{
TextFragmentAbsorber fragment = new TextFragmentAbsorber(findText);
document.Pages.Accept(fragment);
TextFragmentCollection fragmentCollection = fragment.TextFragments;
foreach (TextFragment textFragment in fragmentCollection)
{
textFragment.Text = replaceText;
}
}
