我有一个奇怪的问题,似乎是特定于Mac电脑。我有一个编程,将AWT绘图表面的内容打印到A3纸上。在Linux和Windows机器上,输出是OK的。从Mac打印我使用相同的预设参数获得相同的对话框,打印机按预期在A3纸张上打印,但出于某种原因,图像被缩放以适合A4区域。以下是相关的代码部分:以A4尺度出现在Mac上的Java A3打印
public void print() {
PrinterJob printJob = PrinterJob.getPrinterJob();
PageFormat format = new PageFormat();
format.setOrientation(PageFormat.LANDSCAPE);
double margin = 18; // quarter inch
double m2 = margin * 2;
Paper paper = format.getPaper();
paper.setSize(16.54 * 72, 11.69 * 72); // A3 Landscape
paper.setImageableArea(margin, margin, paper.getWidth()-m2, paper.getHeight()-m2);
format.setPaper(paper);
printJob.setPrintable(this, format);
PrintRequestAttributeSet attributes = new HashPrintRequestAttributeSet();
attributes.add(MediaSizeName.ISO_A3);
attributes.add(OrientationRequested.LANDSCAPE);
attributes.add(new MediaPrintableArea((int)margin, (int)margin,
(int)(paper.getWidth()-m2), (int)(paper.getHeight()-m2),
MediaPrintableArea.INCH));
if(printJob.printDialog(attributes)){
try {
printJob.print(attributes);
} catch(PrinterException pe) {
pe.printStackTrace();
}
}
}
public int print(Graphics g, PageFormat pageFormat, int pageIndex) {
if (pageIndex > 0) {
return(NO_SUCH_PAGE);
} else {
Graphics2D g2d = (Graphics2D)g;
g2d.translate(pageFormat.getImageableX(), pageFormat.getImageableY());
if(this.componentToBePrinted instanceof PlannerView){
setScale(g2d);
}
disableDoubleBuffering(componentToBePrinted);
componentToBePrinted.paint(g2d);
enableDoubleBuffering(componentToBePrinted);
return(PAGE_EXISTS);
}
}
public void setScale(Graphics2D g2d){
PlannerView planner = (PlannerView)this.componentToBePrinted;
planner.resetZoom();
double scale = 1.0/planner.getRowLength();
scale *= 4.0;
g2d.scale(scale, scale);
}
有没有人知道可能是什么原因造成的?
干杯。
