    Public measurement fields use Length<Pt>. Widths, advances, tracking, stretch, shrink, physical targets, insets, font sizes, and optional width limits keep that type across input and output records. Explicit Length conversion functions remain the integer interchange boundary.

    Box.width, Box.trackingAfter, Glue.width, Glue.trackingAfter, Glue.stretch, Glue.shrink, and Penalty.width have type Length<Pt>.

    BreakCluster.advance, BreakCluster.trackingAfter, BreakPolicy.narrowestWordTarget, and BreakPolicy.bodyWordTarget have type Length<Pt>.

    LatinSpacing.fontSizePt, JustificationPolicy.maxAdjustment, and JustificationPolicy.maxGapAdjustment have type Length<Pt>.

    LineGeometry.bodyTarget, LineGeometry.firstTarget, and LineGeometry.dropCapInset have type Length<Pt>.

    PlanLine.target, PlanLine.rawTextWidth, PlanLine.trimmedTextWidth, PlanLine.costTextWidth, and PlanLine.selectedPenaltyWidth have type Length<Pt>. PlanLine.postValidationWidthLimit has type Option<Length<Pt>>.

    An int, a float, or a Length with another unit marker is not an implicit point-length argument. Convert physical units explicitly with toPt() before constructing a typesetting record.

    Indices, counts, penalties, costs, and dimensionless ratios retain their declared types. LatinSpacing.maxLetterSpacingEm is a relative Length<Em>. Resolve it to Length<Pt> with fontSizePt before selecting the computation grid.

    Paragraph.grid selects quantization at the computation boundary. ScaledPoint uses the exact scaled-point integer. MilliPoint uses the existing nearest-even conversion to millipoints. The selected grid never changes the physical interpretation of a public Length<Pt> value.

    Returned distances are converted from the computation grid into Length<Pt> at the output boundary. ParagraphPlan.grid reports the computation policy and is not needed to interpret its distances.

    The public type change preserves the selected cost model. FixedPoint retains its MilliPoint computation requirement. Word-space and CJK ratio calculations keep their independent floor rules. The relative letter-spacing distance is resolved and quantized through the shared Length conversions before it contributes to capacity.

    The public line-badness entry point also receives width, target, and hyphen advance as Length<Pt>. It converts those distances to millipoints at entry and preserves its existing integer cost calculation.

    Item.BoxItem, Item.GlueItem, and Item.PenaltyItem preserve their record payloads. Constructing these records and variants does not plan a paragraph or validate its measurements.

    BoxItem and GlueItem contribute one measured unit each in their encounter order. Their unitIndex fields must be exactly zero through the unit count minus one. PenaltyItem contributes a boundary without consuming a unit index.

    Box.text and Glue.text retain the supplied string, including empty text and multiple Unicode scalars. A measured unit remains indivisible. Unit indices count these records rather than bytes, scalars, or grapheme clusters.

    Box.width and Glue.width include trackingAfter. Width and width minus trackingAfter must both be nonnegative. Tracking may be positive, zero, or negative while those two conditions hold.

    Each width, tracking amount, stretch, and shrink is a Length<Pt>. Paragraph planning quantizes it through the selected grid. A line span sums its unit widths and removes the final unit's trackingAfter.

    Glue.stretch and Glue.shrink are nonnegative adjustment capacities. A box supplies zero capacity. The selected cost and justification policies determine how capacities participate in planning.

    Positive capacity does not itself insert text or change the input records. Unjustified planning performs no distributed adjustment. Text trimming and model-specific glue treatment follow the PlanLine and paragraph contracts.

    breakParagraph returns InvalidInput for a noncontiguous unitIndex, a negative width or capacity, or a negative width before tracking. Validation applies even when a later candidate would discard that unit.

    The function uses the supplied measurements without shaping the text again. It does not reorder or mutate the caller's item array or its records.

    Result and effects

    링크

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

    The width and width minus trackingAfter must be nonnegative.

    Why

    링크

    The record keeps source identity, measured geometry, and boundary policy explicit at the paragraph planning call.

    Give public typesetting distances a point-length type

    Public measurement fields use Length<Pt>. Widths, advances, tracking, stretch, shrink, physical targets, insets, font sizes, and optional width limits keep that type across input and output records. Explicit Length conversion functions remain the integer interchange boundary.

    Box.width, Box.trackingAfter, Glue.width, Glue.trackingAfter, Glue.stretch, Glue.shrink, and Penalty.width have type Length<Pt>.

    BreakCluster.advance, BreakCluster.trackingAfter, BreakPolicy.narrowestWordTarget, and BreakPolicy.bodyWordTarget have type Length<Pt>.

    LatinSpacing.fontSizePt, JustificationPolicy.maxAdjustment, and JustificationPolicy.maxGapAdjustment have type Length<Pt>.

    LineGeometry.bodyTarget, LineGeometry.firstTarget, and LineGeometry.dropCapInset have type Length<Pt>.

    PlanLine.target, PlanLine.rawTextWidth, PlanLine.trimmedTextWidth, PlanLine.costTextWidth, and PlanLine.selectedPenaltyWidth have type Length<Pt>. PlanLine.postValidationWidthLimit has type Option<Length<Pt>>.

    An int, a float, or a Length with another unit marker is not an implicit point-length argument. Convert physical units explicitly with toPt() before constructing a typesetting record.

    Indices, counts, penalties, costs, and dimensionless ratios retain their declared types. LatinSpacing.maxLetterSpacingEm is a relative Length<Em>. Resolve it to Length<Pt> with fontSizePt before selecting the computation grid.

    Paragraph.grid selects quantization at the computation boundary. ScaledPoint uses the exact scaled-point integer. MilliPoint uses the existing nearest-even conversion to millipoints. The selected grid never changes the physical interpretation of a public Length<Pt> value.

    The public type change preserves the selected cost model. FixedPoint retains its MilliPoint computation requirement. Word-space and CJK ratio calculations keep their independent floor rules. The relative letter-spacing distance is resolved and quantized through the shared Length conversions before it contributes to capacity.

    The public line-badness entry point also receives width, target, and hyphen advance as Length<Pt>. It converts those distances to millipoints at entry and preserves its existing integer cost calculation.

    이유

    A physical distance carries the same Length<Pt> type in application geometry and paragraph planning. The type prevents a grid selector or an unlabelled scalar from silently changing the distance.

    Preserve measured units and validate their physical extents

    Item.BoxItem, Item.GlueItem, and Item.PenaltyItem preserve their record payloads. Constructing these records and variants does not plan a paragraph or validate its measurements.

    BoxItem and GlueItem contribute one measured unit each in their encounter order. Their unitIndex fields must be exactly zero through the unit count minus one. PenaltyItem contributes a boundary without consuming a unit index.

    Box.text and Glue.text retain the supplied string, including empty text and multiple Unicode scalars. A measured unit remains indivisible. Unit indices count these records rather than bytes, scalars, or grapheme clusters.

    Box.width and Glue.width include trackingAfter. Width and width minus trackingAfter must both be nonnegative. Tracking may be positive, zero, or negative while those two conditions hold.

    Each width, tracking amount, stretch, and shrink is a Length<Pt>. Paragraph planning quantizes it through the selected grid. A line span sums its unit widths and removes the final unit's trackingAfter.

    Glue.stretch and Glue.shrink are nonnegative adjustment capacities. A box supplies zero capacity. The selected cost and justification policies determine how capacities participate in planning.

    Positive capacity does not itself insert text or change the input records. Unjustified planning performs no distributed adjustment. Text trimming and model-specific glue treatment follow the PlanLine and paragraph contracts.

    breakParagraph returns InvalidInput for a noncontiguous unitIndex, a negative width or capacity, or a negative width before tracking. Validation applies even when a later candidate would discard that unit.

    The function uses the supplied measurements without shaping the text again. It does not reorder or mutate the caller's item array or its records.

    이유

    Measured text already has a source order and physical advances. Preserving those units keeps line breaking compatible with shaping. Explicit tracking and capacities give every planner the same measured input.
