Mark, thank you for your reply.
My first post had a litle error, the error message was:
java.lang.NoSuchFieldError: HALFTONE, and not HHALFTONE as showed.
I´m not using JNI, the error is produced in "super(HALFTONE) " line,
and it is the same if a write "super(PdfDictionary.HALFTONE)".
I´m thinking in a compilation problem. May be I´m not compiling the
library correctly, however, the new PdfHalftone Class is embedded into
the jar file correctly.
what do you think?

That looks remarkably like a syntax error (reffering to double-h-HHALFTONE), but this being a run time exception, that shouldn't happen. Are you calling functions by string name, or through JNI or something?

Subject: [iText-questions] New Dictionary
Hi,
I'm creating pdf documents with only one image on it. I want to add
halftone parameters to the pdf, so the image be printed with the
halftone screen I want.
To do this, I created a PDFHalftone class:
public class PdfHalftone extends PdfDictionary {
public PdfHalftone() {
super(HALFTONE);
put(PdfName.HALFTONETYPE, new PdfNumber((int)1));
put(PdfName.FREQUENCY, new PdfNumber((int)200));
put(PdfName.ANGLE, new PdfNumber((int)0));
put(PdfName.SPOTFUNCTION, PdfName.SIMPLEDOT);
}
}
Furthermore, I added this line to the PDFDictionary class file:
/** This is a possible type of dictionary */
public static final PdfName HALFTONE = PdfName.HALFTONE;
and these ones to the PDFName class:
public static final PdfName HALFTONE = new PdfName("Halftone");
public static final PdfName HALFTONETYPE = new
PdfName("HalftoneType");
public static final PdfName SIMPLEDOT = new PdfName("SimpleDot");
public static final PdfName ANGLE = new PdfName("Angle");
public static final PdfName FREQUENCY = new PdfName("Frequency");
When I call to the PDFHalftone from my Java program: new
com.lowagie.text.pdf.PdfHalftone();
I got the next error message:
Any idea?.
