enum freetype::size_request_type::SizeRequestType

An enumeration type that lists the supported size request types.

Note

The above descriptions only apply to scalable formats. For bitmap formats, the behaviour is up to the driver.

See the note section of FT_Size_Metrics if you wonder how size requesting relates to scaling values.

Enumerator
NOMINAL	The nominal size. The ‘units_per_EM’ field of FT_FaceRec is used to determine both scaling values.
REAL_DIM	The real dimension. The sum of the the ‘ascender’ and (minus of) the ‘descender’ fields of FT_FaceRec are used to determine both scaling values.
BBOX	The font bounding box. The width and height of the ‘bbox’ field of FT_FaceRec are used to determine the horizontal and vertical scaling value, respectively.
CELL	The ‘max_advance_width’ field of FT_FaceRec is used to determine the horizontal scaling value; the vertical scaling value is determined the same way as FT_SIZE_REQUEST_TYPE_REAL_DIM does. Finally, both scaling values are set to the smaller one. This type is useful if you want to specify the font size for, say, a window of a given dimension and 80x24 cells.
SCALES	Specify the scaling values directly.
MAX	MAX.
