+        BitmapCanvasHelper
+
+        Use this helper to handle the XIntegerBitmap part of your
+        implementation.
+
+        @tpl Base
+        Base class to use, most probably one of the
+        WeakComponentImplHelperN templates with the appropriate
+        interfaces. At least XSpriteCanvas and SpriteSurface should be
+        among them (why else would you use this template, then?). Base
+        class must have a 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
+        BaseMutex-provided lock.  Every time 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.
