public Type3Font(PdfWriter writer, char[] chars, boolean colorized)
writer
- the writerchars
- an array of chars corresponding to the glyphs used (not used, present for compatibility only)colorized
- if true
the font may specify color, if false

An example:
Document document = new Document(PageSize.A4); PdfWriter writer = PdfWriter.getInstance(document, new FileOutputStream("type3.pdf")); document.open(); Type3Font t3 = new Type3Font(writer, false); PdfContentByte g = t3.defineGlyph('a', 1000, 0, 0, 750, 750); g.rectangle(0, 0, 750, 750); g.fill(); g = t3.defineGlyph('b', 1000, 0, 0, 750, 750); g.moveTo(0, 0); g.lineTo(375, 750); g.lineTo(750, 0); g.fill(); Font f = new Font(t3, 12); document.add(new Paragraph("ababab", f)); document.close();
