Covered APIs

API	Usage notes
`ApplyIndicReorder`	Dispatches script-specific Indic reorder helpers before GSUB shaping or text output. The parameterless form keeps full-script coverage; the overload taking a `THPDFShapingFeatures` set reorders only the scripts whose shaping flag is present, matching the per-flag isolation applied during text output
`ApplyIndicShaping`	Applies reorder plus the Indic GSUB feature chain and returns synthetic-codepoint text for output
`IndicShapeToGIDs`	Returns the shaped glyph-ID sequence for an Indic string without emitting PDF text
`GetDevanagariCategory`	Classifies Devanagari codepoints for syllable and reorder decisions
`GetBengaliCategory`	Classifies Bengali codepoints for Indic reorder decisions
`GetGujaratiCategory`	Classifies Gujarati codepoints for Indic reorder decisions
`GetTamilCategory`	Classifies Tamil codepoints for Indic reorder decisions
`GetTeluguCategory`	Classifies Telugu codepoints for Indic reorder decisions
`GetKannadaCategory`	Classifies Kannada codepoints for Indic reorder decisions
`GetMalayalamCategory`	Classifies Malayalam codepoints for Indic reorder decisions
`GetSinhalaCategory`	Classifies Sinhala codepoints for Indic reorder decisions
`GetKhmerCategory`	Classifies Khmer codepoints for the shared complex-script reorder path
`GetMyanmarCategory`	Classifies Myanmar codepoints for the shared complex-script reorder path
`sfIndicShaping`	Runs the conservative Indic syllable reorder path before text output without forcing full GSUB feature application
`sfIndicGSUB`	Runs the Indic reorder and GSUB feature chain, then emits shaped glyph IDs through synthetic codepoints

Usage notes

sfIndicShaping izvaja samo preurejanje in ostaja konzervativna možnost. sfIndicGSUB preuredi vsak zlog, uporabi verigo OpenType Indic funkcij, izpiše oblikovane GID-je prek sintetičnih kodnih točk in preide na pot preurejanja, kadar pisavi manjka ustrezni skript GSUB
