setup

public void setup(FontContext fontContext,
                  BidiReorderer bidiReorderer)

                                      FSFont font,
                                      String string)

指定者:

getFSFontMetrics 在接口中 TextRenderer

getWidth

public int getWidth(FontContext fc,
                    FSFont font,
                    String string)

指定者:

getWidth 在接口中 TextRenderer

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.

返回:

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.
