I guess I'm not quite sure what you're saying I should do. Here is the
code for what I was trying to do:
<code> public BufferedImage resizeImage(BufferedImage bimg)
{
PrintRequestAttributeSet aset = new HashPrintRequestAttributeSet();
aset.add(OrientationRequested.LANDSCAPE);
MediaPrintableArea printableArea =
(MediaPrintableArea)Service.getSupportedAttributeValues(MediaPrintableArea.class,
null, aset);
double printWidth = printableArea.getWidth(MediaPrintableArea.INCH);
double printHeight =
printableArea.getHeight(MediaPrintableArea.INCH);
int tempW = bimg.getWidth();
int tempH = bimg.getHeight();
double bimgWidth = tempW/72;
double bimgHeight = tempH/72;
double conversion;
double Xconv = printWidth/bimgWidth;
double Hconv = printHeight/bimgHeight;
if(Xconv > Hconv)
conversion = Xconv;
else
conversion = Hconv;
int bimgNewW = conversion*tempW;
int bimgNewH = conversion*tempH;
BufferedImage newbimg = bimg.getScaledInstance(bimgNewW, bimgNewH,
BufferedImage.SCALE_DEFAULT);
This won't compile. BufferedImage.getScaledInstance() returns an Image.
I was expecting you to draw you image in Printable.print(). I haven't
played with document printing in this style before. Try the little
program below. Change the kittens.jpg to your own image and adjust the
PageFormat with the dialog. This will print the image scaled to fit in
the imageable width.
import java.awt.*;
import java.awt.event.*;
import java.awt.image.*;

import javax.swing.*;
public class test extends JPanel implements Printable {
BufferedImage bi;
int w,h;
volatile static PageFormat pf;
public test() {
try {
bi = ImageIO.read(new File("kittens.jpg"));
w = bi.getWidth();
h = bi.getHeight();
setPreferredSize(new Dimension(w,h));
} catch (IOException ioe) {
ioe.printStackTrace();
}
}
void render(Graphics g, boolean printerFlag) {
if (printerFlag)
g.drawImage(bi,
(int)pf.getImageableX(),
(int)pf.getImageableY(),
(int)pf.getImageableWidth(),
(int)(pf.getImageableWidth()/1.333),null);
else
g.drawImage(bi,0,0,w,h,null);
}
public void paintComponent(Graphics g) {
render(g, false);
}
public int print(Graphics g, PageFormat pageFormat, int pageIndex) {
int retcod = Printable.PAGE_EXISTS;
if (pageIndex == 0) {
render(g, true);
} else
retcod = Printable.NO_SUCH_PAGE;
return retcod;
}
public static void main(String[] args) {
EventQueue.invokeLater(new Runnable() {
public void run() {
JFrame f = new JFrame("test");
f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
final test t = new test();
f.add(t,BorderLayout.CENTER);
JButton b = new JButton("Print");
b.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent ae) {
PrinterJob pj = PrinterJob.getPrinterJob();
pf = pj.defaultPage();
pj.setPrintable(t);
PageFormat pf = pj.pageDialog(pj.defaultPage());
try {
pj.print();
} catch (PrinterException pe) {
pe.printStackTrace();
}
}
});
f.add(b,BorderLayout.SOUTH);
f.pack();
f.setVisible(true);
}
});
}
}
