Method Detail

createPageCoordinatesTranform

public static java.awt.geom.AffineTransform createPageCoordinatesTranform(RenderingContext c,
                                                                          Box box,
                                                                          PageBox page,
                                                                          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 java.awt.geom.AffineTransform createPageMarginCoordinatesTransform(RenderingContext c,
                                                                                 Box box,
                                                                                 PageBox page,
                                                                                 int xTranslate,
                                                                                 int yTranslate)

createDocumentCoordinatesTransform

public static java.awt.geom.AffineTransform createDocumentCoordinatesTransform(Box master,
                                                                               CssContext c,
                                                                               java.awt.geom.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.

getPageTranslateX

private static float getPageTranslateX(float absTranslateX,
                                       int shadowPageNumber,
                                       PageBox page,
                                       CssContext c,
                                       Box box)

createTransform

private static void createTransform(CssContext c,
                                    Box box,
                                    PageBox page,
                                    java.awt.geom.AffineTransform result,
                                    TransformCreator.TransformYOrigin transformYOrigin,
                                    int shadowPageNumber)

page may be null in the case that transformYOrigin is DOCUMENT_TOP. Otherwise, every argument is required. shadowPageNumber is -1 for the base page.

applyTransformFunctions

private static void applyTransformFunctions(float flipFactor,
                                            java.util.List<PropertyValue> transformList,
                                            java.awt.geom.AffineTransform result,
                                            Box box,
                                            CssContext ctx)

convertAngleToRadians

private static float convertAngleToRadians(PropertyValue param)
