31 :
32 : Use this helper to handle the XIntegerBitmap part of your
33 : implementation.
34 :
35 : @tpl Base
36 : Base class to use, most probably one of the
37 : WeakComponentImplHelperN templates with the appropriate
38 : interfaces. At least XIntegerBitmap should be among them (why
39 : else would you use this template, then?). Base class must have
40 : an Base( const Mutex& ) constructor (like the
41 : WeakComponentImplHelperN templates have).
42 :
43 : @tpl CanvasHelper
44 : Canvas helper implementation for the backend in question
45 :
46 : @tpl Mutex
47 : Lock strategy to use. Defaults to using the
48 : OBaseMutex-provided lock. Everytime one of the methods is
49 : entered, an object of type Mutex is created with m_aMutex as
50 : the sole parameter, and destroyed again when the method scope
51 : is left.
52 :
53 : @tpl UnambiguousBase
54 : Optional unambiguous base class for XInterface of Base. It's
55 : sometimes necessary to specify this parameter, e.g. if Base
56 : derives from multiple UNO interface (were each provides its
57 : own version of XInterface, making the conversion ambiguous)
58 :
59 : @see CanvasBase for further contractual requirements towards
60 : the CanvasHelper type, and some examples.
