Problemer med udskrift, PageFormat.setOrientation(int)

Har du prøvet at kalde getPaper og se hvad Java tror formatet er ?

Jeg tror faktisk problemet ligger andetsteds end i print(..., ..., ...)-metoden, eftersom jeg lige fik fat i den samme fejl når jeg udskrev til et JPanel.... Vil du være sød at tjekke det for mig, her er klasserne der skal bruges for at teste:

PrintAndDrawable.class

samt ResultListWeightClass:

package presentation.general;

import java.awt.image.BufferedImage;
import java.awt.*;
import java.awt.font.FontRenderContext;
import java.awt.geom.Rectangle2D;
import java.util.LinkedList;

/**

public class ResultListWeightClass extends PrintAndDrawable {
    private LinkedList fights;

    /**

    * @param fights a list of Fight-objects to generate the tree-hierarchi representation from
    */
    public ResultListWeightClass(LinkedList fights) {
        super(PrintAndDrawable.LANDSCAPE);
        this.fights = fights;

        generateGraphics();
    }

    // todo: has to be fully implemented !!!
    public void generateGraphics() {
        BufferedImage toPaintUpon  = new BufferedImage((int)dim.getWidth(), (int)dim.getHeight(), BufferedImage.TYPE_4BYTE_ABGR);

        Graphics g = toPaintUpon.getGraphics();
        Graphics2D g2d = (Graphics2D)g;

        g.setColor(Color.black);

        // Draw box around margin
        g.drawLine(0, 0, (int)getWidth(), 0);
        g.drawLine(0, 0, 0, (int)getHeight());
        g.drawLine(0, (int)getHeight(), (int)getWidth(), (int)getHeight());
        g.drawLine((int)getWidth(), 0, (int)getWidth(), (int)getHeight());

        g.setFont(new Font("dialog", Font.BOLD, 10));
        g.drawString("Side 1", ((int)getWidth()-getWidthOfText("Side 1", g, g2d)-10), 12);
        g.setFont(new Font("dialog", Font.BOLD, 40));
        g.drawString("Resultat liste", getXForCenteredText("Resultat liste", g, g2d), 50);
        g.drawLine(0, 55, (int)getWidth(), 55);

        // Add image to list
        images.add(toPaintUpon);
    }

    private int getWidthOfText(String text, Graphics g, Graphics2D g2d) {
        FontRenderContext frc = g2d.getFontRenderContext();
        Rectangle2D fontBounds = g.getFont().getStringBounds(text, frc);
        return (int)fontBounds.getWidth();
    }
    private int getXForCenteredText(String text, Graphics g, Graphics2D g2d) {
        int width = getWidthOfText(text, g, g2d);
        return (int)((getWidth()-width)/2);
    }
}

Nu kan jeg nemlig kun få udskrevet hele komponentens bredde hvis den er initialiseret med LANDSCAPE i konstruktoren..... Derfor må der jo være noget i vejen med mit BufferedImage?

Se i hvert fald lige på det, når fejlen både manifesterer sig når man udskriver til komponent såvel som printer, er den ikke printerspecifik :-)

Har skimmet din kode og et hurtigt skud fra hoften, var at du prøvede denne

g.translate((int)pageFormat.getImageableX(), (int)pageFormat.getImageableY());

Indskydes her i din print metode
    System.out.println("x: "+x+" y: "+y+" width: "+width+" height: "+height);
    g.translate((int)pageFormat.getImageableX(), (int)pageFormat.getImageableY());
    g.setFont(new Font("Dialog", Font.PLAIN, 11));

Det skal siges, at jeg ikke er sikker i sagen!

Tjah, men jeg tror ikke det er der det er galt, for den burde jo vise hele billedet når jeg viser billedet i en JLabel. Jeg har også prøvet med translate, og det er ikke det som er galt

Jeg er bange for at jeg må melde pas - det er uden for mit ekspertise område

Jeg fandt selv en løsning, skulle blot sætte clip (forums.java.sun.com er din ven når du søger med de rigtige ord, hehehe)

// translates origin to top left corner of imageable area
g.translate((int)pageFormat.getImageableX(),(int)pageFormat.getImageableY());

// sets the clip size to the imageable area size
g.setClip(0, 0, (int)pageFormat.getImageableWidth(), (int)pageFormat.getImageableHeight());

Lukker her, tak for hjælpen alligevel vel, dog :-)
