Hi all,
I'm sorry if this is the wrong place for my question.
I was seaching for a way to dynamically generate a PDF in Java code by drawing
to a Graphics2D object. When I googled this, I found Apache FOP 1.0 which has a
org.apache.fop.svg.PDFDocumentGraphics2D class (derived from Graphics2D), which
seems to support dynamically generating a PDF by drawing to it.
E.g., I use code like this to generate a PDF and write it to an OutputStream
(using Java 1.7):
PDFDocumentGraphics2D g = new PDFDocumentGraphics2D(false, out, 842, 595);
g.setGraphicContext(new org.apache.xmlgraphics.java2d.GraphicContext());
g.setFont(new Font(Font.SANS_SERIF, Font.PLAIN, 12));
g.drawLine(10, 10, 100, 100);
g.drawString("Hi!", 30, 30);
g.nextPage(); // switch to next page
g.drawString("This is the 2nd page.", 30, 30);
g.finish();
g.dispose();
This seems to be working really well, using the integrated PDF Fonts.
However, I now have the problem that these integrated fonts seem not to support
Unicode characters, e.g. if I use
g.drawString("\u263a", 30, 30);
then the Character is substituted by a "#" and a warning is printed:
Feb 07, 2012 1:10:11 PM org.apache.fop.fonts.Typeface warnMissingGlyph
Warnung: Glyph 9786 (0x263a, smileface) not available in font Helvetica
So, I was searching for a way to embed a TTF font in the PDF. However, I wasn't
successful finding information about it, as it seems the FOP documentation and
examples are only about XSL-FO (which I don't know much about, as I only need
to generate PDFs by drawing to a Graphics2D), but using a PDFDocumentGraphics2D
seems not to be well-documented. So I'm not sure if this is even an intended
way to use FOP, or if there are other/better solutions to generate a PDF by
drawing to a Graphics2D object in Java.
My questions are:
Is using FOP for generating a PDF by drawing to a Graphics2D a recommended way?
Is it possible to embed TTF fonts when drawing to a PDFDocumentGraphics2D
object? If yes, how?
Thanks!
Best Regards,
Konstantin Preißer
