31 /** Helper class for basic canvasbitmap functionality. Extends
32 CanvasHelper with some CanvasBitmap specialities, such as alpha
33 support.
35 Note that a plain CanvasHelper, although it does support the
36 XBitmap interface, has no provision for alpha channel on VCL
37 (at least no efficient one. If the alpha VDev one day gets
38 part of SAL, we might change that).

45 /** Set a new bitmap on this helper.
47 This method late-initializes the bitmap canvas helper,
48 providing it with the necessary device and output
49 objects. The internally stored bitmap representation is
50 updated from the given bitmap, including any size
51 changes. Note that the CanvasHelper does <em>not</em> take
52 ownership of the SpriteCanvas object, nor does it perform
53 any reference counting. Thus, to prevent reference counted
54 objects from deletion, the user of this class is
55 responsible for holding ref-counted references to those
56 objects!

59 Content of this bitmap is used as our new content (our

63 Reference device for this canvas bitmap
65 @param rOutDevProvider
66 Reference output device. Used to create matching bitmap.
