GetModelPosition()

SW_DLLPUBLIC sal_Int32 sw::Justify::GetModelPosition	(	const KernArray &	rKernArray,
		sal_Int32	nLen,
		tools::Long	nX
	)

Get model position base on given kern array.

Parameters

rKernArray	text positions from OutDev::GetTextArray().
nLen	number of elements to process in rKernArray.
nX	the visual position

SnapToGrid()

SW_DLLPUBLIC tools::Long sw::Justify::SnapToGrid	(	KernArray &	rKernArray,
		std::u16string_view	aText,
		sal_Int32	nStt,
		sal_Int32	nLen,
		tools::Long	nGridWidth,
		bool	bForceLeft
	)

Snap ideographs to text grids: a) Ideographic open brackets are aligned to the rightmost edge of spanned grids so that.

b) Ideographic close brackets, ideographic comma, and ideographic fullstop are aligned to the leftmost edge of spanned grids so that they can be closer to the previous ideograph. c) Other ideographs are aligned to the center of the spanned grids.

Parameters

[in,out]	rKernArray	text positions from OutDev::GetTextArray().
	aText	string used to determine where space and kern are inserted.
	nStt	starting index of rText.
	nLen	number of elements to process in rKernArray and rText.
	nGridWidth	width of a text grid
	bForceLeft	for align to the left edge of the grid disregard of the punctuation type. This is useful for calculate text width, line break, and conversion model position.

Returns

the delta offset of first glyph so text origin can be updated accordingly.

SnapToGridEdge()

SW_DLLPUBLIC void sw::Justify::SnapToGridEdge	(	KernArray &	rKernArray,
		sal_Int32	nLen,
		tools::Long	nGridWidth,
		tools::Long	nSpace,
		tools::Long	nKern
	)

Snap ideographs to text grids edge ( used when snap to char is off ): space will be distributed ( in case that alignment is set to justify.

).

Parameters

[in,out]	rKernArray	text positions from OutDev::GetTextArray().
	nLen	number of elements to process in rKernArray and rText.
	nGridWidth	width of a text grid
	nSpace	amount of space distributed under justify text alignment mode.
	nKern	letter spacing.

SpaceDistribution()

SW_DLLPUBLIC void sw::Justify::SpaceDistribution	(	KernArray &	rKernArray,
		std::u16string_view	aText,
		sal_Int32	nStt,
		sal_Int32	nLen,
		tools::Long	nSpaceAdd,
		tools::Long	nKern,
		bool	bNoHalfSpace
	)

Distribute space between words and letters.

Parameters

[in,out]	rKernArray	text positions from OutDev::GetTextArray().
	aText	string used to determine where space and kern are inserted.
	nStt	starting index of rText.
	nLen	number of elements to process in rKernArray and rText.
	nSpaceAdd	amount of space to insert for each CH_BLANK.
	nKern	amount of space to insert between letters.
	bNoHalfSpace	whether to split the space into two halves. Split spaces are inserted before and after CH_BLANK. Set to true in word line mode and for Arabic text to avoid splitting.
