Method Detail

createGraphics

protected Graphics2D createGraphics(FontContext context)

getAscent

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).

The baseline info does not take any leading into account.

Parameters: c the character that is used to select the script type.

Returns:

getCharWidth

public long getCharWidth(int character)

getDescent

public long getDescent()

getFont

public Font getFont()

getItalicAngle

public long getItalicAngle()

Returns zero, as the AWT renderer will take care of the italic rendering already. We do not have to apply any special transformations to the font to make it look italic.

Returns: always zero.
