◆ GetModelPosition()

SW_DLLPUBLIC sal_Int32 sw::Justify::GetModelPosition ( const std::vector< sal_Int32 > &  rKernArray,
sal_Int32  nLen,
tools::Long  nX 
)

Get model position base on given kern array.

Parameters
rKernArraytext positions from OutDev::GetTextArray().
nLennumber of elements to process in rKernArray.
nXthe visual position

◆ SnapToGrid()

SW_DLLPUBLIC tools::Long sw::Justify::SnapToGrid ( std::vector< sal_Int32 > &  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]rKernArraytext positions from OutDev::GetTextArray().
aTextstring used to determine where space and kern are inserted.
nSttstarting index of rText.
nLennumber of elements to process in rKernArray and rText.
nGridWidthwidth of a text grid
bForceLeftfor 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 ( std::vector< sal_Int32 > &  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]rKernArraytext positions from OutDev::GetTextArray().
nLennumber of elements to process in rKernArray and rText.
nGridWidthwidth of a text grid
nSpaceamount of space distributed under justify text alignment mode.
nKernletter spacing.

◆ SpaceDistribution()

SW_DLLPUBLIC void sw::Justify::SpaceDistribution ( std::vector< sal_Int32 > &  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]rKernArraytext positions from OutDev::GetTextArray().
aTextstring used to determine where space and kern are inserted.
nSttstarting index of rText.
nLennumber of elements to process in rKernArray and rText.
nSpaceAddamount of space to insert for each CH_BLANK.
nKernamount of space to insert between letters.
bNoHalfSpacewhether 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.
