THotPDF Script Shaping Preprocess Methods

THotPDF API reference

記錄 N'Ko、Adlam、Hanifi Rohingya、Thai/Lao、Hebrew、Javanese、Tai Viet、Meetei Mayek、Khmer 與 Myanmar text 的目前 script-level preprocess 與 RTL cursive helpers

Delphi 語法

AutoShapeNko、AutoShapeAdlam 與 AutoShapeHanifiRohingya 會將 RTL cursive GSUB positional paths 連接到 text output。sfThaiLaoReorder 會分解 SARA AM 並排序 tone marks，sfHebrewReorder 會在 mark placement 前依 canonical combining class 排序 niqqud，而 Javanese、Tai Viet、Meetei Mayek、Khmer 與 Myanmar flags 會在 cmap-to-GID mapping 前 normalize script-specific cluster order
