Hello everyone!
I've been familiarising myself with Batik for converting data from the JGo
graphing libraries to a SVG document to print off using Batik but I've hit a
problem.
When I attempt to print off the SVGDcoument, the call to print fails. This
is the exception I get:
java.lang.NullPointerException
[2013-12-05 09:46:33,957] ERROR Netbase (Stream.java:175) [AWT-EventQueue-0]

: at sun.print.RasterPrinterJob.print(RasterPrinterJob.java:1461)
And this is the code I am using to get to this point:
PrintTranscoder transcoder = new PrintTranscoder();
transcoder = setupTranscoder(transcoder);
PrinterJob job = PrinterJob.getPrinterJob();
job.setPrintable(transcoder);
try {
job.setPrintService(settings.getPrintService());
PrintRequestAttributeSet set = new HashPrintRequestAttributeSet();
set.add(settings.getPaperSize());
job.print(set);
} catch (PrinterException e1) {
e1.printStackTrace();
}
[...]
private PrintTranscoder setupTranscoder(PrintTranscoder transcoder) {
TranscoderInput input = new TranscoderInput(document);
transcoder.transcode(input, null);
return transcoder;
}
