如何在java中打印图像

Question

我们如何在java中打印缓冲图像？我们可以将FileInputStream发送到Print Service,但我需要向它发送缓冲的Image.

FileInputStream fin = new FileInputStream("YOurImageFileName.PNG");
Doc doc = new SimpleDoc(fin, DocFlavor.INPUT_STREAM.GIF, null);
job.print(doc, pras);

可能吗？

Answer 1

PrinterJob printJob = PrinterJob.getPrinterJob();
printJob.setPrintable(new Printable() {
        public int print(Graphics graphics, PageFormat pageFormat, int pageIndex) throws PrinterException {
                if (pageIndex != 0) {
                    return NO_SUCH_PAGE;
                }
                graphics.drawImage(image, 0, 0, image.getWidth(), image.getHeight(), null);
                return PAGE_EXISTS;
        }
});     
try {
    printJob.print();
} catch (PrinterException e1) {             
    e1.printStackTrace();
}
