public Type3Font(PdfWriter writer,
char[] chars,
boolean colorized)
writer - the writerchars - an array of chars corresponding to the glyphs used (not used, prisent for compability only)colorized - if true the font may specify color, if false no color commands are allowed
and only images as masks can be used
public Type3Font(PdfWriter writer,
boolean colorized)
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();
