Hi folks,
I would appreciate any advice on the following issue, I have been trying all
kinds of encoding such as utf-8, iso-8859-1, etc. Also I have tried setting
some basefonts (very trial and error), but no luck so far - I admit openly
that I'm an itextsharp newb, and a c# newb too - thanks in advance for your
understanding.
I am reading a small portion of a pdf page set by a rectangular area using
ITextExtractionStrategy, then writing out the text into a csv file.
Everything seems to work except that every time there is a dash, "-" in the
pdf, it gets written out to my csv as a null character (shows "NUL " in
notepad++)
- code is pretty straightforward, it just reads through all pdf's in a
folder and pulls data off the first page, then writes that out to a text
file:
using System.Configuration;
using System.Collections.Specialized;
using System;
using System.IO;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using iTextSharp.text;
using iTextSharp.text.pdf;
using iTextSharp.text.pdf.parser;
namespace ConsoleApplication1
{
class Program
{
static void Main(string[] args)
{
string PDFPath = ConfigurationManager.AppSettings["PDFPath"];
string CSVPath = ConfigurationManager.AppSettings["CSVPath"];
int fileCounter = 0;
System.IO.StreamWriter fileout = new
System.IO.StreamWriter(CSVPath);
foreach (string fileName in Directory.GetFiles(PDFPath))
{
try
{
PdfReader reader = new PdfReader(fileName);
//define rectangular area of page where the microtext
is...and the itext "strategy"
System.util.RectangleJ rect = new
System.util.RectangleJ(0, 0, 3000, 30);
RenderFilter[] renderFilter = new RenderFilter[1];
renderFilter[0] = new RegionTextRenderFilter(rect);
ITextExtractionStrategy textExtractionStrategy = new
FilteredTextRenderListener(new LocationTextExtractionStrategy(),
renderFilter);
string tempString =
PdfTextExtractor.GetTextFromPage(reader, 1, textExtractionStrategy); //
.Replace("\n", "")
string numberOfPages = reader.NumberOfPages.ToString();
//write line to file
fileout.WriteLine(tempString + "|" +
Path.GetFileName(fileName) + "|" + numberOfPages);
}
catch (IOException)
{
Console.WriteLine("Bad PDF!");
}
catch (Exception e)
{
Console.WriteLine("The MicroTextReader process failed:
{0}", e.ToString());
}
}
fileout.Close();
// Suspend the screen. (keep console window open and in
suspension - allows to view console output....)
//Console.ReadLine();
}
}
}
Any advice here? Thanks for your consideration!
