ascent

public float ascent

Indicates the font ascent, that is, the distance from the font's baseline to the top of a character. Some characters might extend above the font ascent line.

bottom

public float bottom

Indicates the maximum descent of the font. No character extends further below the font's baseline than this height.

descent

public float descent

Indicates the font ascent, that is, the distance from the font's baseline to the bottom of a character. Some characters might extend below the font descent line.

leading

public float leading

Indicates the leading, that is, the space to be reserved between the descent of a line and the ascent of the next line.

top

public float top

Indicates the maximum ascent of the font. No character extends further above the font's baseline than this height.

FontMetrics

public FontMetrics(float top,
                   float ascent,
                   float descent,
                   float bottom,
                   float leading)

A constructor used to create a FontMetrics instance based on the specified maximum ascent and descent, font ascent and descent, and leading.

参数:

top - Indicates the maximum ascent of the font described by this FontMetrics object.

ascent - Indicates the distance from the font's baseline to the top of a character.

descent - Indicates the distance from the font's baseline to the bottom of a character.

bottom - Indicates the maximum descent of the font described by this FontMetrics object.

leading - Indicates the space to be reserved between the descent of a line and the ascent of the next line.
