  Hi!
  
  I’m trying to extract some text from a PDF using GetFragment but if I use standard X Y coordinates of the PDF area the output seems to be wrong, I get some words but not of the right area
  
  If I know the rectangle where I want to extract the words how do I pass this information to the getFragment function in the right way? Is there some conversion which I should do first?

  Thank you very much!
  
  Simona

  Hello Simona,

  These methods take position values in point, so please ensure you provide the values in this unit only. If you are still facing the issue, please share the pdf file with which you are facing this issue along with the points.

  Please see the following link to see how to get text from point:

  Lets say I have the PDF attached here, I know that the rectangle containing the “ELEMENTI RETRIBUTIVI” text is a RectangleF(25, 170, 20, 65), how do I convert that in points? Is it possible to extract that text?

  I know that that PDF has been written in a weird order, and maybe that could be a problem with the text extraction too, I don’t know.

  In the real case I need to extract text in other areas where the data are dynamic, but the process is the same

  Thank you very much,
  
  Simona

  Hello Simona,

  As per the developers, the HitTest method is not intended for this scenario. Please use ITextMap.GetFragmentFromRect(RectangleF) method for this case (it is an extension method)

  var g = doc1.Pages[0].Graphics;
  var rect = new RectangleF(25, 170, 20, 65);
  var tmf = tmap.GetFragmentFromRect(rect);
   Console.WriteLine(tmap.GetText(tmf));

  If you need any other help, please feel free to ask.

  Regards,
  
  Prabhat Sharma.
