#12 problem to generate pdf with tomcat

[pdeville]

Since The class PDFGraphics instanciate JFrame in getFontMetrics method there is a problem to use gnujpdf on a web server.

On linux I got message:
X11 display not available

On windows it works a moment but After severals use of the lib I got :
Out of memory no more window handle.

Here is my suggestion for getFontMetrics :

Line 1435 :
public FontMetrics getFontMetrics(Font font) {
BufferedImage image = new BufferedImage(100,100,BufferedImage.TYPE_INT_RGB);
// Frame dummy = new Frame();
// dummy.addNotify();
// Image image = dummy.createImage(100, 100);
if (image == null) {
System.err.println("getFontMetrics: image is null");
}
Graphics graphics = image.getGraphics();
return graphics.getFontMetrics(font);

}

I tested this and it works well.

The code takes more times to hangs (arround 50 request to return OutOfMemoryError)

This last change works since 3 days without problem (1000 access per hour).

/**
* Returns the FontMetrics for a font.
* <p>This doesn't work correctly. Perhaps having some way of mapping
* the base 14 fonts to our own FontMetrics implementation?
* @param font The java.awt.Font to return the metrics for
* @return FontMetrics for a font
*/
public FontMetrics getFontMetrics(Font font) {

return Toolkit.getDefaultToolkit().getFontMetrics(font);

}

}

File Added: PDFGraphics.java
