| /** Helper template to handle XIeeeDoubleBitmap method forwarding to |
| BitmapCanvasHelper |
| |
| Use this helper to handle the XIeeeDoubleBitmap part of your |
| implementation. |
| |
| @tpl Base |
| Base class to use, most probably one of the |
| WeakComponentImplHelperN templates with the appropriate |
| interfaces. At least XIeeeDoubleBitmap 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. |
