Constructor Details

XGraphicsEnvironment

public XGraphicsEnvironment()
Creates a new XGraphicsEnvironment. This loads the configuration if there is one present and initializes the XGraphicsDevices in the environment. If there is no configuration, then there is one default device initialized with the local main X device.

Method Details

createGraphics

public Graphics2D createGraphics(BufferedImage image)
Returns a Graphics instance suitable for drawing on top of the BufferedImage.
Overrides:
createGraphics in interface GraphicsEnvironment
Parameters:
image - the buffered image to create a graphics for
Returns:
a Graphics2D instance for drawing on the BufferedImage

getAllFonts

public Font[] getAllFonts()
Returns an array of the one-point size fonts available in this environment. From there, the user can select the font and derive the correct one of proper size and attributes, using deriveFont. Only one master version of each font appears in this array; if a font can be derived from another, it must be created in that way.
Overrides:
getAllFonts in interface GraphicsEnvironment
Returns:
the array of available fonts
Since:
1.2
See Also:
GraphicsEnvironment.getAvailableFontFamilyNames(), Font.deriveFont(int,float)

getAvailableFontFamilyNames

public String[] getAvailableFontFamilyNames()
Returns an array of the font family names available in this environment. This allows flexibility in choosing the style of font, while still letting the Font class decide its best match.
Overrides:
getAvailableFontFamilyNames in interface GraphicsEnvironment
Returns:
the array of available font families
Since:
1.2
See Also:
GraphicsEnvironment.getAllFonts(), Font.getFamily()

public String[] getAvailableFontFamilyNames(Locale l)
Returns an array of the font family names available in this environment, localized to the current Locale if l is non-null. This allows flexibility in choosing the style of font, while still letting the Font class decide its best match.
Overrides:
getAvailableFontFamilyNames in interface GraphicsEnvironment
Parameters:
l - the locale to use
Returns:
the array of available font families, localized
Since:
1.2
See Also:
GraphicsEnvironment.getAllFonts(), Font.getFamily()
