freetypy.SIZE_REQUEST_TYPE¶

class freetypy.SIZE_REQUEST_TYPE¶

Modes for selecting the size of a bitmap font.

NOMINAL: The nominal size. The Face.units_per_em is used to determine both scaling values.
REAL_DIM: The real dimension. The sum of the the ascender and (minus of) the descender are used to determine both scaling values.
BBOX: The font bounding box. The width and height of the bbox are used to determine the horizontal and vertical scaling value, respectively.
CELL: The max_advance_width is used to determine the horizontal scaling value; the vertical scaling value is determined the same way as 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.

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