Hi,
I'm trying to use iText 5.0.2 to extract the text from a pdf file
using the following code...
PdfReader reader = new PdfReader("C:/development/May.pdf");
PdfReaderContentParser parser = new
PdfReaderContentParser(reader);
PrintWriter out = new PrintWriter(System.out);
TextExtractionStrategy strategy;
for (int i = 1; i <= reader.getNumberOfPages(); i++) {
strategy = parser.processContent(i, new
SimpleTextExtractionStrategy());
out.println(strategy.getResultantText());
}
When I run this code I get the following exception.
java.lang.NullPointerException
at com.itextpdf.text.pdf.DocumentFont.<init>(DocumentFont.java:114)
at
com.itextpdf.text.pdf.CMapAwareDocumentFont.<init>(CMapAwareDocumentFont.java:79)
at
com.itextpdf.text.pdf.parser.PdfContentStreamProcessor$SetTextFont.invoke(PdfContentStreamProcessor.java:591)

at
com.itextpdf.text.pdf.parser.PdfReaderContentParser.processContent(PdfReaderContentParser.java:41)
I believe that this is something todo with the font not being available?
I have used www.identifont.com and think that the font is Heldustry.
Should this not be available on my machine if acrobat reader can read
the file?
Can anyone give me a some help making this text extraction work?
Kind Regards
Ben Short
