Class LargePageable.TranslatedPrintable

public final class LargePageable.TranslatedPrintable

implements Printable

This inner class's sole responsibility is to translate the coordinate system before invoking a canvas's painter. The coordinate system is translated in order to get the desired portion of a canvas to line up with the top of a page.

public LargePageable.TranslatedPrintable(Printable painter, Point2D origin)

Create a new Printable that will translate the drawing done by painter on to the imageable area of a page.

Parameters:

painter - The object responsible for drawing the canvas

origin - The point in the canvas that will be mapped to the upper-left corner of the page's imageable area.

public int print(Graphics graphics, PageFormat pageFormat, int pageIndex)
           throws java.awt.print.PrinterException

Prints the page at the specified index into the specified Graphics context in the specified format. A PrinterJob calls the Printableinterface to request that a page be rendered into the context specified by graphics. The format of the page to be drawn is specified by pageFormat. The zero based index of the requested page is specified by pageIndex. If the requested page does not exist then this method returns NO_SUCH_PAGE; otherwise PAGE_EXISTS is returned. The Graphics class or subclass implements the PrinterGraphics interface to provide additional information. If the Printable object aborts the print job then it throws a PrinterException.

Parameters:

graphics - the context into which the page is drawn

pageFormat - the size and orientation of the page being drawn

pageIndex - the zero based index of the page to be drawn

Returns: PAGE_EXISTS if the page is rendered successfully or NO_SUCH_PAGE if pageIndex specifies a non-existent page.

Throws:

java.awt.print.PrinterException thrown - when the print job is terminated.
