getFSFontMetrics

public FSFontMetrics getFSFontMetrics(FontContext fc,
                                      FSFont font,
                                      String string)

getRenderingHints

public Object getRenderingHints()

If anti-alias text is enabled, the value from RenderingHints to use for AA smoothing in Java2D. Defaults to RenderingHints.VALUE_TEXT_ANTIALIAS_ON.

Returns:

Current AA rendering hint

getGlyphPositions

public float[] getGlyphPositions(OutputDevice outputDevice,
                                 FSFont font,
                                 String text)

This method gets glyph positions for purposes of selecting text. WE are not too worried about selecting text at this point so we just use the first font available.
