The HVAR (Horizontal Metrics Variations) table

Fields

version: MajorMinor

Major version number of the horizontal metrics variations table — set to 1. Minor version number of the horizontal metrics variations table — set to 0.

item_variation_store: OffsetMarker<ItemVariationStore, WIDTH_32>

Offset in bytes from the start of this table to the item variation store table.

advance_width_mapping: NullableOffsetMarker<DeltaSetIndexMap, WIDTH_32>

Offset in bytes from the start of this table to the delta-set index mapping for advance widths (may be NULL).

lsb_mapping: NullableOffsetMarker<DeltaSetIndexMap, WIDTH_32>

Offset in bytes from the start of this table to the delta-set index mapping for left side bearings (may be NULL).

rsb_mapping: NullableOffsetMarker<DeltaSetIndexMap, WIDTH_32>

Offset in bytes from the start of this table to the delta-set index mapping for right side bearings (may be NULL).
