| 898 |
* el alto y ancho de la imagen a dibujar (wImg, hImg), as? como el punto donde se va a pintar dentro
|
| 899 |
* del graphics (pt). Finalmente se llama a updateImage del driver para que pinte y una vez dibujado
|
| 900 |
* se pasa a trav?s de la funci?n renderizeRaster que es la encargada de aplicar la pila de filtros
|
| 901 |
* sobre el Image que ha devuelto el driver.

*
|

|

* se aplica sobre la esquina superior izquierda de esta la matriz de transformaci?n del ViewPortData

|
| 906 |
* funci?n calculateNewView que devuelve la petici?n ajustada al extent de la imagen (sin rotar). Si
|
| 907 |
* el raster est? rotado necesitaremos para la transformaci?n el resultado de la funci?n coordULRotateRaster.
|
| 908 |
* Lo que hace esta ?ltima es colocar la petici?n que ha sido puesta en coordenadas de la imagen sin rotar
|
| 909 |
* (para pedir al driver de forma correcta) otra vez en coordenadas de la imagen rotada (para calcular su
|
| 910 |
* posici?n de dibujado).
|

*
|
| 912 |
* Para dibujar sobre el Graphics2D el raster rotado aplicaremos la matriz de transformaci?n con los

* par?metros de Shear sobre este Graphics de forma inversa. Como hemos movido el fondo tendremos que
|
| 914 |
* recalcular ahora el punto donde se comienza a dibujar aplicandole la transformaci?n sobre este
|
| 915 |
* at.inverseTransform(pt, pt);. Finalmente volcamos el BufferedImage sobre el Graphics volviendo a dejar
