Hi,

is there a way to loop the lines of a PDF page getting line index and length?

Hi Al

Only something like:

var
  idx, outIndex, outLength: Integer;
  s: String;
begin
  Memo1.Clear;
  idx := 0;
  While idx < MAXINT do // Infinite loop
  begin
    ImageEnView1.PdfViewer.CharIndexToLine( idx, outIndex, outLength );
    if outLength = 0 then
      BREAK;
    s := ImageEnView1.PdfViewer.GetText( outIndex, outLength );
    memo1.Lines.Add( outIndex.ToString + ',' + outLength.ToString + ': ' + Trim( s ));
    idx := outIndex + outLength + 1;
  end;
end;
