Example 3 with SunGraphicsEnvironment

use of sun.java2d.SunGraphicsEnvironment in project jdk8u_jdk by JetBrains.

the class SwingUtilities2 method isLocalDisplay.

/* Used to help decide if AA text rendering should be used, so
     * this local display test should be additionally qualified
     * against whether we have XRender support on both ends of the wire,
     * as with that support remote performance may be good enough to turn
     * on by default. An additional complication there is XRender does not
     * appear capable of performing gamma correction needed for LCD text.
