JavaFX打印自定义纸张大小

Question

在JavaFX中,我想将照片打印到10x15纸张上.有一些Paper constansts,但没有100x150 mm的常数.

是否可以创建自己的Paper以在PageLayout中使用它？

谢谢.

PageLayout pageLayout = printer.createPageLayout(Paper.JAPANESE_POSTCARD, PageOrientation.LANDSCAPE, Printer.MarginType.EQUAL);
        double scaleX = pageLayout.getPrintableWidth() / node.getBoundsInParent().getWidth();
        double scaleY = pageLayout.getPrintableHeight() / node.getBoundsInParent().getHeight();
    node.getTransforms().add(new Scale(scaleX, scaleY));
    PrinterJob job = PrinterJob.createPrinterJob(printer);
    if (job != null) {
        System.out.println("Job created!");
        boolean success = job.printPage(node);
        if (success) {
            System.out.println("Job successfully finished!");
            job.endJob();
        } else {
            System.out.println("Job NOT successful!");
        }
    }

您可以使用类PrintHelper,它可以访问Paper的包私有构造函数.

Paper photo = PrintHelper.createPaper("10x15", 100, 150, Units.MM);
