org.mapfish.print.attribute.map.MapfishMapContext
Utility class that adjusts the bounds and the map size in case a rotation is set. Also it provides an {@link AffineTransform} to render the layer graphics.

                             final MapfishMapContext transformer,
                             final boolean isFirstLayer) {
        Rectangle paintArea = new Rectangle(transformer.getMapSize());
        MapBounds bounds = transformer.getBounds();


        MapfishMapContext layerTransformer = transformer;
        if (transformer.getRotation() != 0.0 && !this.supportsNativeRotation()) {
            // if a rotation is set and the rotation can not be handled natively
            // by the layer, we have to adjust the bounds and map size
            paintArea = new Rectangle(transformer.getRotatedMapSize());
            bounds = transformer.getRotatedBounds();
            graphics2D.setTransform(transformer.getTransform());
            Dimension mapSize = new Dimension(paintArea.width, paintArea.height);
            layerTransformer = new MapfishMapContext(bounds, mapSize, transformer.getRotation(), transformer.getDPI(),
                    transformer.getRequestorDPI(), transformer.isForceLongitudeFirst(), transformer.isDpiSensitiveStyle());
        }
