 Finds the union of this region and the the non-transparent pixels of a
-bitmap.  If the bitmap has a mask then it will be used, otherwise the
-colour to be treated as transparent may be specified, along with an
+bitmap. Colour to be treated as transparent is specified in the
+\arg{transColour} argument, along with an
 optional colour tolerance value.
