CWsBitmap Class Reference
| class CWsBitmap : public CFbsBitmap |
Window server bitmap.
This is a bitmap to which the window server already has a handle. Functions which take a window server bitmap are faster than equivalent functions which take a CFbsBitmap.

Constructor & Destructor Documentation
CWsBitmap()
Default constructor. Developers should use the other constructor overload.
CWsBitmap(RWsSession &)
Constructor which takes a window server session as an argument.
Member Functions Documentation
Create(const TSize &, TDisplayMode)
Creates a bitmap, specifying the size and display mode.
This function, if successful, always causes a flush of the window server buffer.
CFbsBitmap::Create()
Parameters
| const TSize & aSizeInPixels | The size of the bitmap to be created. |
| TDisplayMode aDispMode | The display-mode of the bitmap to be created. |
Duplicate(TInt)
Makes this bitmap a duplicate of the specified bitmap.
This function, if successful, always causes a flush of the window server buffer.
CFbsBitmap::Duplicate()
Parameters
| TInt aHandle | The handle of the bitmap to be duplicated. |
InternalizeL(RReadStream &)
Internalises a CWsBitmap from the read stream.
The presence of this function means that the standard templated operator>>() can be used to internalise objects of this class.
This function always causes a flush of the window server buffer.
Parameters
| RReadStream & aStream | The stream from which to internalise the bitmap. |
Load(const TDesC &, TInt32, TBool)
Loads a bitmap from a file.
If aShareIfLoaded is ETrue the bitmap will be allowed to be shared by a number of font and bitmap server clients.
This function, if successful, always causes a flush of the window server buffer.
CFbsBitmap::Load()
Parameters
| const TDesC & aFileName | The filename of the multibitmap (.mbm) file containing the bitmap to be loaded. |
| TInt32 aId | The identifier of the bitmap in the .mbm file which should be loaded. |
| TBool aShareIfLoaded = ETrue | Specifies whether or not the loaded bitmap will be made available for sharing between font and bitmap server clients. |
Reset()
Releases the bitmap's handle from the font and bitmap server.
The function also decrements the bitmap's access count in the font and bitmap server. The server-side bitmap is deleted only if the access count for the bitmap decrements to zero.
