class CWsBitmap : public CFbsBitmap, public MWsClientClass;
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.
MWsClientClass - Base class for all classes whose objects are clients of the window server.
CBase -
Base class for all classes to be instantiated on the heap.
CFbsBitmap - Note that this class is not intended for user derivation. A bitmap managed by th...

IMPORT_C TInt Create(const TSize &aSizeInPixels, TDisplayMode aDispMode);
Creates a bitmap, specifying the size and display mode.
This function, if successful, always causes a flush of the window server buffer.

Makes this bitmap a duplicate of the specified bitmap.
This function, if successful, always causes a flush of the window server buffer.

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(const TDesC &,TInt32,TBool)Loads a specific bitmap from a multi-bitmap file. The bitmap may be shared by ot...IMPORT_C void InternalizeL(RReadStream &aStream);
Internalises a CWsBitmap from the read stream.
The presence of this function means that the standard templated operator>>(RReadStream &,T &) can be used to internalise objects of this class.
This function always causes a flush of the window server buffer.
|
IMPORT_C void 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.
