问题
I have a pdf that has been created using the Foxit form designer. On my design system, I have the barcode font installed. The barcode font is used in one of the AcroFields. It appears that foxit does not embed the font in the document.
I also have customers that do not have the barcode font installed in their computers, and thus I would like to embed the font into the PDF. Is there a way for me to embed a font that is used in the AcroFields into the PDF using iText?
EDIT: The font seems to be included in the text, but not the fields, Therefore the font(barcode) will not print.

I'm almost sure that you got an answer by now, but maybe others would like to get a detailed view on the solution. Below is the sample java code I used to embed fonts in the generated PDF (useful only in some cases, as the size of the documents increases dramatically). As a free tool to create the PDF forms, I have used the OpenOffice writer, by adding forms inside the documents and exporting the documents as PDF files :
PdfReader pdfTemplate = new PdfReader(templateName);
ByteArrayOutputStream out = new ByteArrayOutputStream();
BaseFont unicode = BaseFont.createFont(unicodeFontPath, BaseFont.IDENTITY_H, BaseFont.EMBEDDED);
PdfStamper stamper = new PdfStamper(pdfTemplate, out);
//assigning the font to the field
stamper.getAcroFields().setFieldProperty("myField", "textfont", unicode, null);
stamper.getAcroFields().setField("myField", someValue);
stamper.close();
pdfTemplate.close();

PdfContentByte ab = yourPDFWriter.getDirectContent();
// field: PdfFormField.createTextField(...);
PdfAppearance ap = ab.createAppearance(320, 30); // size of field
field.setDefaultAppearanceString(ap);
That should do the trick.
