Glyph Tools
Browse all available glyph tools.
Available tools
- Glyph Advance Run Tab Stop Placement Place glyph-run tab positions at the next strictly greater explicit stop, then repeat a supplied positive interval after the last stop; no text shaping.
- Glyph Advance Scale Transform Scale explicit glyph advances and known box coordinates by a nonnegative uniform factor; no hinted rasterization or font metric inference.
- Glyph Baseline Shift Transform Shift known glyph ink boxes vertically by an explicit baseline offset while preserving advances and missing-box evidence; no font-size or shaping changes.
- Glyph Box Run Extents Union explicitly supplied glyph ink boxes placed by accumulated horizontal advances; missing boxes contribute no invented ink, no font shaping.
- Glyph Cluster Index Audit Audit supplied integer UTF-16 glyph cluster positions for bounds and decreasing order separately; decreasing clusters may be valid RTL shaping, not automatically corruption.
- Glyph Cluster Source Span Table Derive cluster source spans from the next greater distinct supplied UTF-16 cluster index, supporting repeated and reverse-ordered glyph clusters; does not infer graphemes.
- Glyph Empty Ink Classifier Classify supplied glyph boxes as positive-area ink, degenerate empty ink or explicitly unknown; missing is never silently empty.
- Glyph Fallback Metric Delta Table Compare paired supplied primary/fallback glyph advances and total run shift; caller must establish glyph correspondence, no shaping equivalence.
- Glyph ID Coverage Audit Audit observed glyph metric IDs against an explicit font inventory, preserving occurrence indexes and missing metrics; no font-file lookup or fallback shaping.
- Glyph Ink Gap Table Report signed adjacent placed glyph ink gaps with null when either box is missing; negative values retain ink overlap.
- Glyph Missing Box Audit Identify supplied glyph records with explicitly unknown ink boxes; absence is not assumed to be an empty-space glyph.
- Glyph Overhang Budget Budget horizontal ink overhang outside the explicit advance run, using null when no ink boxes are known; no font rendering.
- Glyph Pair Adjustment Conflict Audit Audit conflicting caller pair-adjustment observations by exact ordered glyph ID pair; repeated equal values are not conflicts.
- Glyph Pair Adjustment Lookup Lookup every explicit pair-adjustment record for two glyph IDs, retaining conflicting duplicate values rather than assuming authoritative font kerning.
- Glyph Tabular Advance Consistency Check supplied glyph advances for tabular consistency within an explicit nonnegative absolute tolerance; does not certify a font feature or digit repertoire.
