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)
|
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.
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)
|
IMPORT_C
TInt
|
Duplicate
|
(
|
TInt
|
aHandle
|
)
|
|
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.
