@@ -75,7 +75,7 @@ sfImageTransformPlugin supports several different types of thumbnailing:
   * fit - Creates an image of the specified size and fits the thumbnailed inside. This will produce uniform size thumbnails. (default)
   * scale - Scales the image to fit inside the specified dimensions.
   * inflate, deflate - simply resizes the image to the specified dimensions, proportions are not preserved.
-  * left, right, top, bottom, center - scales the image to specified size and then crops
+  * left, right, top, bottom, center, bottom-left, bottom-right, top-left, top-right - scales the image to specified size and then crops
 
 *Example 3. Thumbnailing*
