+ /** Helper template to handle XIeeeFloatBitmap method forwarding to
+ BitmapCanvasHelper
+
+ Use this helper to handle the XIeeeFloatBitmap part of your
+ implementation.
+
+ @tpl Base
+ Base class to use, most probably one of the
+ WeakComponentImplHelperN templates with the appropriate
+ interfaces. At least XIeeeFloatBitmap should be among them (why
+ else would you use this template, then?). Base class must have
+ an Base( const Mutex& ) constructor (like the
+ WeakComponentImplHelperN templates have).
+
+ @tpl CanvasHelper
+ Canvas helper implementation for the backend in question
+
+ @tpl Mutex
+ Lock strategy to use. Defaults to using the
+ OBaseMutex-provided lock. Everytime one of the methods is
+ entered, an object of type Mutex is created with m_aMutex as
+ the sole parameter, and destroyed again when the method scope
+ is left.
+
+ @tpl UnambiguousBase
+ Optional unambiguous base class for XInterface of Base. It's
+ sometimes necessary to specify this parameter, e.g. if Base
+ derives from multiple UNO interface (were each provides its
+ own version of XInterface, making the conversion ambiguous)
+
+ @see CanvasBase for further contractual requirements towards
+ the CanvasHelper type, and some examples.
