Hello,
If you execute this code in the atttached PDF, you will realize that the objBusca.text.Size.Width is taking a smaller value than real value.
List<PdfTextFind> objBusca = new List<PdfTextFind>();
objBusca.AddRange(p_page.FindText("PREFEITURA MUNICIPAL DE JOINVILLE",TextFindParameter.IgnoreCase ).Finds);
objBusca.text.Size.Width
The returned value is 289,but this isn't correct. If you apply the extract in the positions results, you will be get just part of the string "PREFEITURA MUNICIP".
Att,
Fernando.
