getWidth

public double getWidth()

Returns the width, in 1/72nds of an inch, of the page. This method takes into account the orientation of the page when determining the width.

Returns:

the width of the page.

getHeight

Returns:

the height of the page.

getImageableX

public double getImageableX()

Returns the x coordinate of the upper left point of the imageable area of the Paper object associated with this PageFormat. This method takes into account the orientation of the page.

Returns:

the x coordinate of the upper left point of the imageable area of the Paper object associated with this PageFormat.

getImageableY

public double getImageableY()
