private static float convertAngleToRadians(PropertyValue param)

createDocumentCoordinatesTransform	back to summary
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.

createPageCoordinatesTranform	back to summary
public static 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	back to summary
public static AffineTransform createPageMarginCoordinatesTransform(RenderingContext c, Box box, PageBox page, int xTranslate, int yTranslate)

createTransform	back to summary
private static void createTransform(CssContext c, Box box, PageBox page, 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.

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