function AddShapedText(const Text, Font: WString; FontSize: Single; X, Y: Double; out Shaped: TPdfShapedText; Direction: TPdfTextDirection = ptdAuto; Color: TColor = clBlack; Alpha: Byte = $FF): Boolean;
Former Unicode-tekst gennem den native Windows-script-motor, indlæser den valgte systemskrifttype én gang og skriver eksplicit positionerede glyffer gennem PDFiums CID Type 2-skrifttype-API
ptdAuto opløser afsnittets grundretning fra det første stærke tegn, mens eksplicitte left-to-right- og right-to-left-tilstande er tilgængelige til applikationsstyret layout
Each glyph receives a bounded CID mapping and a generated ToUnicode entry, including cluster-aware mappings for ligatures and contextual forms
The text object carries the original logical string in ActualText, so conforming consumers can recover logical reading order even when positioned glyph geometry is visual-order bidi content
TPdf.Text follows PDFium's physical bidi extraction order and may therefore differ from the original logical input order
TPdfShapedText returns font bytes, total width, glyph and logical-character counts, and visual runs containing bidi levels, glyph IDs, advances, offsets, and source clusters
Use ShapePdfText for shaping without modifying a document, or instantiate TPdfUniscribeTextShaper with TPdfTextShapingOptions when explicit character, glyph, and run budgets are required
Input, glyph, and run limits fail closed before unbounded allocation
Runs sharing one baseline are emitted as one text object and glyph positions are generated in linear time
The method requires the PDFium CID Type 2 font, character-code, position, marked-content, and content-regeneration exports
