A list of bit-field constants used with FT_TrueTypeGX_Validate to indicate which TrueTypeGX/AAT Type tables should be validated.

values

+ + + + + + + + + + + + +

FT_VALIDATE_feat	+ Validate ‘feat’ table. +
FT_VALIDATE_mort	+ Validate ‘mort’ table. +
FT_VALIDATE_morx	+ Validate ‘morx’ table. +
FT_VALIDATE_bsln	+ Validate ‘bsln’ table. +
FT_VALIDATE_just	+ Validate ‘just’ table. +
FT_VALIDATE_kern	+ Validate ‘kern’ table. +
FT_VALIDATE_opbd	+ Validate ‘opbd’ table. +
FT_VALIDATE_trak	+ Validate ‘trak’ table. +
FT_VALIDATE_prop	+ Validate ‘prop’ table. +
FT_VALIDATE_lcar	+ Validate ‘lcar’ table. +
FT_VALIDATE_GX	+ Validate all TrueTypeGX tables (feat, mort, morx, bsln, just, kern, opbd, trak, prop and lcar). +

FT_TrueTypeGX_Validate

+Defined in FT_GX_VALIDATE_H (freetype/ftgxval.h). +

+
+  FT_EXPORT( FT_Error )
+  FT_TrueTypeGX_Validate( FT_Face   face,
+                          FT_UInt   validation_flags,
+                          FT_Bytes  tables[FT_VALIDATE_GX_LENGTH],
+                          FT_UInt   table_length );
+
+

Validate various TrueTypeGX tables to assure that all offsets and indices are valid. The idea is that a higher-level library which actually does the text layout can access those tables without error checking (which can be quite time consuming).

input

+ + + + +

face	+ A handle to the input face. +
validation_flags	+ A bit field which specifies the tables to be validated. See FT_VALIDATE_GXXXX for possible values. +
table_length	+ The size of the ‘tables’ array. Normally, FT_VALIDATE_GX_LENGTH should be passed. +

output

+ + +

tables

The array where all validated sfnt tables are stored. The array itself must be allocated by a client.

return

FreeType error code. 0 means success.

note

This function only works with TrueTypeGX fonts, returning an error otherwise.

After use, the application should deallocate the buffers pointed to by each ‘tables’ element, by calling FT_TrueTypeGX_Free. A NULL value indicates that the table either doesn't exist in the font, the application hasn't asked for validation, or the validator doesn't have the ability to validate the sfnt table.

FT_TrueTypeGX_Free

+Defined in FT_GX_VALIDATE_H (freetype/ftgxval.h). +

+
+  FT_EXPORT( void )
+  FT_TrueTypeGX_Free( FT_Face   face,
+                      FT_Bytes  table );
+
+

Free the buffer allocated by TrueTypeGX validator.

input

+ + + +

face	+ A handle to the input face. +
table	+ The pointer to the buffer allocated by FT_TrueTypeGX_Validate. +

note

This function must be used to free the buffer allocated by FT_TrueTypeGX_Validate only.

FT_VALIDATE_CKERNXXX

+Defined in FT_GX_VALIDATE_H (freetype/ftgxval.h). +

+
+#define FT_VALIDATE_MS     ( FT_VALIDATE_GX_START << 0 )
+#define FT_VALIDATE_APPLE  ( FT_VALIDATE_GX_START << 1 )
+
+#define FT_VALIDATE_CKERN  ( FT_VALIDATE_MS | FT_VALIDATE_APPLE )
+
+

A list of bit-field constants used with FT_ClassicKern_Validate to indicate the classic kern dialect or dialects. If the selected type doesn't fit, FT_ClassicKern_Validate regards the table as invalid.

values

+ + + + +

FT_VALIDATE_MS	+ Handle the ‘kern’ table as a classic Microsoft kern table. +
FT_VALIDATE_APPLE	+ Handle the ‘kern’ table as a classic Apple kern table. +
FT_VALIDATE_CKERN	+ Handle the ‘kern’ as either classic Apple or Microsoft kern table. +

FT_ClassicKern_Validate

+Defined in FT_GX_VALIDATE_H (freetype/ftgxval.h). +

+
+  FT_EXPORT( FT_Error )
+  FT_ClassicKern_Validate( FT_Face    face,
+                           FT_UInt    validation_flags,
+                           FT_Bytes  *ckern_table );
+
+

Validate classic (16-bit format) kern table to assure that the offsets and indices are valid. The idea is that a higher-level library which actually does the text layout can access those tables without error checking (which can be quite time consuming).

The ‘kern’ table validator in FT_TrueTypeGX_Validate deals with both the new 32-bit format and the classic 16-bit format, while FT_ClassicKern_Validate only supports the classic 16-bit format.

input

+ + + +

face	+ A handle to the input face. +
validation_flags	+ A bit field which specifies the dialect to be validated. See FT_VALIDATE_CKERNXXX for possible values. +

output

+ + +

ckern_table

A pointer to the kern table.

return

FreeType error code. 0 means success.

note

After use, the application should deallocate the buffers pointed to by ‘ckern_table’, by calling FT_ClassicKern_Free. A NULL value indicates that the table doesn't exist in the font.

FT_ClassicKern_Free

+
+  FT_EXPORT( void )
+  FT_ClassicKern_Free( FT_Face   face,
+                       FT_Bytes  table );
+
+

Free the buffer allocated by classic Kern validator.

input

+ + + +

face	+ A handle to the input face. +
table	+ The pointer to the buffer that is allocated by FT_ClassicKern_Validate. +

note

This function must be used to free the buffer allocated by FT_ClassicKern_Validate only.
