public long getAscent()

From the baseline to the

Returns:

getBaselines

public BaselineInfo getBaselines(int c, BaselineInfo info)

Baselines are defined for scripts, not glyphs. A glyph carries script information most of the time (unless it is a neutral characters or just weird).

Parameters: c

Returns:

getCharWidth

public long getCharWidth(int codePoint)

getDescent

public long getDescent()

getItalicAngle

public long getItalicAngle()

getKerning

public long getKerning(int previous, int codePoint)

getLeading

public long getLeading()

getMaxAscent

public long getMaxAscent()

getMaxCharAdvance

public long getMaxCharAdvance()

getMaxDescent

public long getMaxDescent()

getMaxHeight

public long getMaxHeight()

getOverlinePosition

public long getOverlinePosition()

getStrikeThroughPosition

public long getStrikeThroughPosition()

getUnderlinePosition

public long getUnderlinePosition()

getXHeight

public long getXHeight()

The height of the lowercase 'x'. This is used as hint, which size the lowercase characters will have.

Returns:

isUniformFontMetrics

public boolean isUniformFontMetrics()

Is it guaranteed that the font always returns the same baseline info objct?

Returns: true, if the baseline info in question is always the same, false otherwise.
