Contents

Description

Font-wide extent values, measured in font units.

Note that typically ascender is positive and descender negative, in coordinate systems that grow up.

Construct a FontExtentsT struct initialized to zero.

Methods

The height of typographic ascenders.

Get the value of the “ascender” field. When overloading is enabled, this is equivalent to

get fontExtentsT #ascender

Set the value of the “ascender” field. When overloading is enabled, this is equivalent to

set fontExtentsT [ #ascender := value ]

The depth of typographic descenders.

Get the value of the “descender” field. When overloading is enabled, this is equivalent to

get fontExtentsT #descender

Set the value of the “descender” field. When overloading is enabled, this is equivalent to

set fontExtentsT [ #descender := value ]

The suggested line-spacing gap.

Get the value of the “line_gap” field. When overloading is enabled, this is equivalent to

get fontExtentsT #lineGap

Set the value of the “line_gap” field. When overloading is enabled, this is equivalent to

set fontExtentsT [ #lineGap := value ]
