Examples with Region sun.java2d.pipe.Region used on opensource projects

Example 11 with Region

use of sun.java2d.pipe.Region in project jdk8u_jdk by JetBrains.

the class OGLUtilities method getOGLScissorBox.

/**
     * Returns the Rectangle describing the OpenGL scissor box on the
     * Java 2D surface associated with the given Graphics object.  When a
     * third-party library is performing OpenGL rendering directly
     * into the visible region of the associated surface, this scissor box
     * must be set to avoid drawing over existing rendering results.
     *
     * Note that the x/y values in the returned Rectangle object represent
     * the lower-left corner of the scissor region, relative to the
     * lower-left corner of the given surface.
     *
     * @param g the Graphics object for the corresponding destination surface;
     * cannot be null
     * @return a Rectangle describing the OpenGL scissor box for the given
     * Graphics object and corresponding destination surface, or null if the
     * given Graphics object is invalid or the clip region is non-rectangular
