ConstructL ( CBitmapFont , TInt, TInt, RHeap )

TInt	ConstructL	(	CBitmapFont *	aBitmapFont,
			TInt	aScript,
			TInt	aLanguage,
			RHeap *	iHeap
		)	[pure virtual]

construct a shaper object

Parameter	Description
aBitmapFont	The font to be shaped.

Returns: KErrNone if this font can be shaper or system wide error code

ExtendedInterface ( TUid )

IMPORT_C void *

ExtendedInterface

(

TUid

aInterfaceId

)

[virtual]

For future expansion. Any overriders must base-call if aInterface is unrecognized.

WARNING: Function for internal use ONLY. Compatibility is not guaranteed in future releases.

Parameter	Description
aInterfaceId	The ID of the interface to return.

Returns: A pointer to the extension interface.

ShapeText ( TShapeHeader &, const TInput &, RHeap )

TInt	ShapeText	(	TShapeHeader *&	aOutput,
			const TInput &	aInput,
			RHeap *	aHeapForOutput
		)	[pure virtual]

If possible, shape the text described by aInput, placing the output on aHeapForOutput.

Parameter	Description
aOutput	The output, as a newly allocate object on aHeapForOutput.
aInput	The input text and other parameters.
aHeapForOutput	On success, aOutput should be allocated from this and nothing else. On failure, nothing should be allocated from it.
