                                                            int shadowPageNumber)

Creates a transform that can be applied to a page, either PDF or Java2D. This transform can be applied on top of other tranforms already in effect on the page.

createPageMarginCoordinatesTransform

public static AffineTransform createPageMarginCoordinatesTransform(RenderingContext c,
                                                                   Box box,

                                                                   int xTranslate,
                                                                   int yTranslate)

createDocumentCoordinatesTransform

public static AffineTransform createDocumentCoordinatesTransform(Box master,
                                                                 CssContext c,
                                                                 AffineTransform _parentCtm)

Creates an absolute transform in document coordinates. This is typically used to figure out what pages the box will fall on. The _parentCtm may be null in case the parent layer uses the identity tranform. If it is not null it will be cloned before use.
