FreeType-2.2.1 API Reference

FreeType Version

Synopsis

Note that those functions and macros are of limited use because even a new release of FreeType with only documentation changes increases the version number.

FREETYPE_XXX


#define FREETYPE_MAJOR  2
#define FREETYPE_MINOR  2
#define FREETYPE_PATCH  1

These three macros identify the FreeType source code version. Use FT_Library_Version to access them at runtime.

values

FREETYPE_MAJOR	The major version number.
FREETYPE_MINOR	The minor version number.
FREETYPE_PATCH	The patch level.

note

The version number of FreeType if built as a dynamic link library with the ‘libtool’ package is not controlled by these three macros.

FT_Library_Version


  FT_EXPORT( void )
  FT_Library_Version( FT_Library   library,
                      FT_Int      *amajor,
                      FT_Int      *aminor,
                      FT_Int      *apatch );

Return the version of the FreeType library being used. This is useful when dynamically linking to the library, since one cannot use the macros FREETYPE_MAJOR, FREETYPE_MINOR, and FREETYPE_PATCH.

input

library

A source library handle.

output

amajor	The major version number.
aminor	The minor version number.
apatch	The patch version number.

note

The reason why this function takes a ‘library’ argument is because certain programs implement library initialization in a custom way that doesn't use FT_Init_FreeType.

In such cases, the library version might not be available before the library object has been created.
