TextFragment fragment = new TextFragment(“Q. Thank you for reading my question”);
In the above string, I would like to change only Q. to red.
What should I do?
Thank you for contacting support.
We would like to share with you that one TextFragment can include many Text Segments so you can break a TextFragment into several TextSegments and manipulate them as per your requirements. Please try using below code snippet as an example to achieve your requirements.
Document document = new Document();
document.Pages.Add();
Page page = document.Pages[1];
var textfragment1 = new TextFragment("Q. Thank you for reading my question");
var textfragment2 = new TextFragment("");
TextSegmentCollection collection1 = textfragment1.IsolateTextSegments(0, 2);
TextSegmentCollection collection2 = textfragment1.IsolateTextSegments(2, textfragment1.Text.Length);
TextSegment segment1 = new TextSegment();
segment1 = collection1[1];
segment1.TextState.ForegroundColor = Color.Red;
textfragment2.Segments.Add(segment1);
TextSegment segment2 = new TextSegment();
segment2 = collection2[1];
textfragment2.Segments.Add(segment2);
page.Paragraphs.Add(textfragment2);
document.Save(dataDir + "Test_18.5.pdf");
It adds different text in a single line. We hope this will be helpful. Please feel free to contact us if you need any further assistance.
