THotPDF.SetFontFallbackChain Method

Replaces the ordered fallback-face list for a Unicode script group

Declaration

procedure SetFontFallbackChain(Script: THPDFFontScript;
  const FontNames: array of AnsiString);

Parameters

• Script selects the Unicode script group
• FontNames lists installed face names in resolution order

Return value

This procedure returns no value

Usage notes

• Empty names and case-insensitive duplicates are removed
• Script-specific faces are tried before the hfsCommon chain
• Resolution rejects silent GDI substitution to a different face
• A face may be listed under any family name it carries, so 'SimSun' works on a Chinese system where Windows reports the face by its Chinese name
