I would think that if you had a pdf and you added a Text Field to it in Acrobat
then specified the font to use in this field as *not* one of the base 14 fonts,
it would embed the entire font not a subset. Also, I get that kerning
information is not saved for text on a page as it is rendered as specific
characters at specific positions but if the font were to be used in a form
field, wouldn't the kerning information need to be included in the file since
the user could type anything into the field? Here's the problem I'm having.
I've been able to extract the font used in the text field and (I think) make a
BaseFont using BaseFont.createFont(PRIndirectReference). However, when I try
to use PdfContentByte.showText(String, BaseFont) I get a NullPointerException.
Here is some example code, can anyone give me any ideas on what I could be doing
wrong? Thanks.
PdfReader reader = null;
try {
reader = new PdfReader(path to pdf file);
}
catch (IOException iox) { }
PdfDictionary catalog = reader.getCatalog();
PdfIndirectReference acroform =
(PdfIndirectReference)catalog.get(PdfName.ACROFORM);
PdfDictionary object = (PdfDictionary)PdfReader.getPdfObject(acroform);
PdfDictionary resources = (PdfDictionary)object.get(PdfName.DR);
PdfDictionary font = (PdfDictionary)resources.get(PdfName.FONT);
Set keys = font.getKeys();
Iterator iter = keys.iterator();
PdfName name = (PdfName)iter.next();
BaseFont docfont = BaseFont.createFont((PRIndirectReference)font.get(name));
com.lowagie.text.Rectangle pageSize = new com.lowagie.text.Rectangle(100, 100);
com.lowagie.text.Document document = new com.lowagie.text.Document(pageSize);
try {
FileOutputStream fileOutputStream = null;
fileOutputStream = new FileOutputStream(new File("c:\\documents and
settings\\danielb\\desktop\\temp.pdf"));
PdfWriter writer = PdfWriter.getInstance(document, fileOutputStream);
document.open();
PdfContentByte cb = writer.getDirectContent();
cb.beginText();
cb.setFontAndSize(docfont, 12);
cb.showText("test");
cb.endText();
document.close();
}
