  [in] BOOL   bEnable
);

Parameters

[in] lpszFacename

Pointer to the facename of the font to be added or removed from the typeface exclusion list.

[in] bEnable

Boolean controlling operation on typeface exclusion list. If nonzero, then the facename will be removed from the list; if zero, the facename will be added to the list.

Remarks

The function TTEnableEmbeddingForFacename uses a typeface exclusion list to control whether a specific font can be embedded. This list identifies all fonts that should NOT be embedded and is shared by all authoring clients on a single system.

An authoring client can embed fonts without referencing the typeface exclusion list (that is, without using TTEnableEmbeddingForFacename). Embedding fonts in a document results in the following tradeoffs.

  • Provides all font information within a document so the appropriate client can render the document.
  • Adds size to a document.
  • Complicates streaming read and write operations to a document and uses more processing bandwidth.
  • Makes a document less readable by other applications.
  • Can leave copyright issues unmanaged, if the type exclusion list is not used.
Two additional functions, TTIsEmbeddingEnabled and TTIsEmbeddingEnabledForFacename, access the typeface exclusion list to provide enabling status.

The typeface exclusion list is stored in the registry key HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Shared Tools\t2embed. The default typeface exclusion list should contain the following named value entries representing the Microsoft Windows core fonts.

Value name Data type Data value
Arial REG_DWORD 0
Arial Bold REG_DWORD 0
Arial Bold Italic REG_DWORD 0
Arial Italic REG_DWORD 0

Times New Roman REG_DWORD 0
