When creating a new face object (e.g. with
FT_New_Face
), an
FT_Size
object is automatically created and used to store
all pixel-size dependent information, available
in the "face->size" field.
It is however possible to create more sizes for a
given face, mostly in order to manage several
character pixel sizes of the same font family and
style. See
FT_New_Size
and
FT_Done_Size
.
Note that
FT_Set_Pixel_Sizes
and
FT_Set_Char_Size
only modify the contents of the current "active"
size; you thus need to use
FT_Activate_Size
to change it.
99% of applications won't need the functions
provided here, especially if they use the caching
sub-system, so be cautious when using these.
