    LatinSpacing stores minWordSpaceRatio and maxWordSpaceRatio as dimensionless float values, maxLetterSpacingEm as Length<Em>, and fontSizePt as Length<Pt>. There is no implicit scalar or cross-unit conversion.

    Record construction and field reads store and return the supplied values. They do not validate a paragraph policy or resolve the relative length. Field expressions follow ordinary source-order evaluation once.

    A paragraph validates every supplied LatinSpacing record before planning. This validation also applies in Unjustified mode and with the KnuthPlass cost model.

    minWordSpaceRatio must be finite and between 0.8 and 1.0 inclusive. maxWordSpaceRatio must be finite and between 1.0 and 1.33 inclusive. Invalid ratios return Err containing TypesetError.InvalidPolicy.

    maxLetterSpacingEm must be between 0em and 0.015em inclusive on the stored relative grid. The upper bound is 983 em ticks. A negative tick or 984 ticks returns Err containing TypesetError.InvalidPolicy.

    fontSizePt must have a strictly positive scaled-point count. A one-scaled-point font is valid even when the paragraph uses millipoints. Zero and negative fonts return Err containing TypesetError.InvalidPolicy, including when letter spacing is zero.

    InvalidPolicy carries explanatory text. Its exact message text and the order among independent invalid policy fields are not fixed by this contract.

    Resolve the stored maximum with maxLetterSpacingEm.resolve(fontSizePt). The stored relative count is multiplied by the physical font count and divided by 65,536 with one nearest-even rounding to scaled points. No ambient font is read.

    Convert the resolved result to the selected computation grid. ScaledPoint preserves its integer count. MilliPoint applies the shared nearest-even conversion. Every eligible gap receives this rounded bound before multiplication by the gap count.

    An eligible Latin letter gap lies between adjacent retained text units. Each unit must contain an alphabetic scalar and every scalar must be in U+0041 through U+024F, U+0300 through U+036F, or U+1E00 through U+1EFF. Paragraph trimming determines the retained units.

    The retained line uses this capacity path when it contains a CJK unit, or contains a Latin letter unit and no other alphabetic unit. A non-Latin unit containing an alphabetic scalar counts as another alphabetic unit. Paragraph classification determines CJK units.

    Let S be the sum of the grid widths of retained units whose text is U+0020. Word shrink capacity is floor(float(S) * (1.0 - minWordSpaceRatio)). Word stretch capacity is floor(float(S) * (maxWordSpaceRatio - 1.0)). Each expression keeps that binary64 evaluation order and its independent floor.

    The letter stretch contribution is the eligible gap count times the quantized relative limit. CJK capacity retains its separate floor rule. Combining these contributions does not repeat font resolution or round their total as one relative length.

    Unjustified mode does not apply spacing capacity. KnuthPlass obtains stretch and shrink from glue after the shared policy validation. FixedPoint uses the validated Latin spacing in its justification capacity and requires MilliPoint.

    Resolution, integer accumulation, and capacity arithmetic use their checked numeric contracts. Overflow stops with TPZ4004 and does not return InvalidPolicy. Validation and conversion perform no I/O and do not mutate the record.

    For 0.01em at 12pt, 655 relative ticks resolve to 7,860 scaled points and then 120 millipoints. For 0.0078125em at 24pt, each gap receives 188 millipoints. Two such gaps provide 376 millipoints.

    Select this field from a value of its named type without call parentheses.

    Store the maximum word-space ratio. Paragraph admission requires a finite value from 1.0 through 1.33 inclusive and returns TypesetError.InvalidPolicy otherwise.

    Resolve relative letter spacing through Length

    LatinSpacing stores minWordSpaceRatio and maxWordSpaceRatio as dimensionless float values, maxLetterSpacingEm as Length<Em>, and fontSizePt as Length<Pt>. There is no implicit scalar or cross-unit conversion.

    Record construction and field reads store and return the supplied values. They do not validate a paragraph policy or resolve the relative length. Field expressions follow ordinary source-order evaluation once.

    A paragraph validates every supplied LatinSpacing record before planning. This validation also applies in Unjustified mode and with the KnuthPlass cost model.

    minWordSpaceRatio must be finite and between 0.8 and 1.0 inclusive. maxWordSpaceRatio must be finite and between 1.0 and 1.33 inclusive. Invalid ratios return Err containing TypesetError.InvalidPolicy.

    maxLetterSpacingEm must be between 0em and 0.015em inclusive on the stored relative grid. The upper bound is 983 em ticks. A negative tick or 984 ticks returns Err containing TypesetError.InvalidPolicy.

    fontSizePt must have a strictly positive scaled-point count. A one-scaled-point font is valid even when the paragraph uses millipoints. Zero and negative fonts return Err containing TypesetError.InvalidPolicy, including when letter spacing is zero.

    InvalidPolicy carries explanatory text. Its exact message text and the order among independent invalid policy fields are not fixed by this contract.

    Resolve the stored maximum with maxLetterSpacingEm.resolve(fontSizePt). The stored relative count is multiplied by the physical font count and divided by 65,536 with one nearest-even rounding to scaled points. No ambient font is read.

    Convert the resolved result to the selected computation grid. ScaledPoint preserves its integer count. MilliPoint applies the shared nearest-even conversion. Every eligible gap receives this rounded bound before multiplication by the gap count.

    An eligible Latin letter gap lies between adjacent retained text units. Each unit must contain an alphabetic scalar and every scalar must be in U+0041 through U+024F, U+0300 through U+036F, or U+1E00 through U+1EFF. Paragraph trimming determines the retained units.

    The retained line uses this capacity path when it contains a CJK unit, or contains a Latin letter unit and no other alphabetic unit. A non-Latin unit containing an alphabetic scalar counts as another alphabetic unit. Paragraph classification determines CJK units.

    Let S be the sum of the grid widths of retained units whose text is U+0020. Word shrink capacity is floor(float(S) * (1.0 - minWordSpaceRatio)). Word stretch capacity is floor(float(S) * (maxWordSpaceRatio - 1.0)). Each expression keeps that binary64 evaluation order and its independent floor.

    The letter stretch contribution is the eligible gap count times the quantized relative limit. CJK capacity retains its separate floor rule. Combining these contributions does not repeat font resolution or round their total as one relative length.

    Unjustified mode does not apply spacing capacity. KnuthPlass obtains stretch and shrink from glue after the shared policy validation. FixedPoint uses the validated Latin spacing in its justification capacity and requires MilliPoint.

    Resolution, integer accumulation, and capacity arithmetic use their checked numeric contracts. Overflow stops with TPZ4004 and does not return InvalidPolicy. Validation and conversion perform no I/O and do not mutate the record.

    For 0.01em at 12pt, 655 relative ticks resolve to 7,860 scaled points and then 120 millipoints. For 0.0078125em at 24pt, each gap receives 188 millipoints. Two such gaps provide 376 millipoints.

    이유

    One relative length model gives a letter-spacing limit an explicit font and unit. Validating the stored policy before planning separates field construction from recoverable policy errors. Per-gap quantization makes the permitted adjustment reproducible.
