Constructor & Destructor Documentation

RShapeInfo()

IMPORT_C

RShapeInfo

(

)

Construct an RShapeInfo.

Member Functions Documentation

Advance()

TPoint16

Advance

(

)

const

Returns the pen advance these glyphs require.

Close()

IMPORT_C void

(

)

Frees the memory associated with this shaping information.

EndOfShapedText()

TInt

EndOfShapedText

(

)

GetContext()

TAny *

GetContext

(

)

GlyphCount()

TInt

GlyphCount

(

)

const

Returns the number of glyphs in the shaped output.

GlyphPositions()

const TPoint16 *

GlyphPositions

(

)

const

Returns the array of positions for the glyphs returned by Glyphs, and the total advance for the text.

Glyphs()

const TInt32 *

Glyphs

(

)

const

Returns the array of glyphs. These must be ORed with 0x80000000 to make glyph numbers that functions like CFbsFont::Rasterize can accept to avoid confusing glyph numbers with Unicode character numbers. GlyphCount

Indices()

const TInt16 *

Indices

(

)

const

Returns the array of indices.

IsOpen()

IMPORT_C TBool

IsOpen

(

)

Checks if this shaping information is still occupying memory.

Open(const CFont *, const TDesC16 &, TInt, TInt, TInt, TInt)

TInt	Open	(	const CFont *	aFont,
			const TDesC16 &	aText,
			TInt	aStartOfTextToShape,
			TInt	aEndOfTextToShape,
			TInt	aScriptCode,
			TInt	aLanguageCode
		)

Perform shaping on the text in aText between aStartOfTextToShape and aEndOfTextToShape, based on the script conventions implied by aScriptCode.

Parameters

const CFont * aFont	The font to use for the shaping.
const TDesC16 & aText	The text, including context.
TInt aStartOfTextToShape	The start position within aText of the text to be shaped.
TInt aEndOfTextToShape	The end position within aText of the text to be shaped.
TInt aScriptCode	The script code for the script being shaped.
TInt aLanguageCode	The language code for the language being shaped.
