Synopsis
This section contains the declaration of functions specific to BDF and PCF fonts.
BDF_PropertyType
Defined in FT_BDF_H (freetype/ftbdf.h).
A list of BDF property types.
values
BDF_PROPERTY_TYPE_NONE |
Value 0 is used to indicate a missing property.
|
BDF_PROPERTY_TYPE_ATOM |
Property is a string atom.
|
BDF_PROPERTY_TYPE_INTEGER |
Property is a 32-bit signed integer.
|
BDF_PROPERTY_TYPE_CARDINAL |
Property is a 32-bit unsigned integer.
|
BDF_Property
Defined in FT_BDF_H (freetype/ftbdf.h).
typedef struct BDF_PropertyRec_* BDF_Property;
A handle to a BDF_PropertyRec
structure to model a given BDF/PCF property.
BDF_PropertyRec
Defined in FT_BDF_H (freetype/ftbdf.h).
This structure models a given BDF/PCF property.
fields
FT_Get_BDF_Charset_ID
Defined in FT_BDF_H (freetype/ftbdf.h).
FT_EXPORT( FT_Error )
FT_Get_BDF_Charset_ID( FT_Face face,
const char* *acharset_encoding,
const char* *acharset_registry );
Retrieve a BDF font character set identity, according to the BDF specification.
input
face |
A handle to the input face.
|
output
acharset_encoding |
Charset encoding, as a C string, owned by the face.
|
acharset_registry |
Charset registry, as a C string, owned by the face.
|
return
FreeType error code. 0 means success.
note
This function only works with BDF faces, returning an error otherwise.
FT_Get_BDF_Property
Defined in FT_BDF_H (freetype/ftbdf.h).
Retrieve a BDF property from a BDF or PCF font file.
input
face |
A handle to the input face.
|
name |
The property name.
|
output
return
FreeType error code. 0 means success.
note
This function works with BDF and PCF fonts. It returns an error otherwise. It also returns an error if the property is not in the font.
A ‘property’ is a either key-value pair within the STARTPROPERTIES ... ENDPROPERTIES block of a BDF font or a key-value pair from the info->props
array within a FontRec
structure of a PCF font.
Integer properties are always stored as ‘signed’ within PCF fonts; consequently, BDF_PROPERTY_TYPE_CARDINAL
is a possible return value for BDF fonts only.
In case of error, aproperty->type
is always set to BDF_PROPERTY_TYPE_NONE
.
