ConstructL(CBitmapFont *, TInt, TInt, RHeap *)

TInt ConstructL(CBitmapFont *aBitmapFont,
TIntaScript,
TIntaLanguage,
RHeap *iHeap
)[pure virtual]

construct a shaper object

Parameters

CBitmapFont * aBitmapFontThe font to be shaped.
TInt aScript
TInt aLanguage
RHeap * iHeap

ExtendedInterface(TUid)

IMPORT_C void *ExtendedInterface(TUidaInterfaceId)[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.

Parameters

TUid aInterfaceIdThe ID of the interface to return.

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. TShapeHeader

Parameters

TShapeHeader *& aOutputThe output, as a newly allocate object on aHeapForOutput.
const TInput & aInputThe input text and other parameters.
RHeap * aHeapForOutputOn success, aOutput should be allocated from this and nothing else. On failure, nothing should be allocated from it.
