Example 6 with ImageCapabilities

use of java.awt.ImageCapabilities in project javatari by ppeccin.

the class MonitorPanel method canvasSetRenderingMode.

public void canvasSetRenderingMode() {
    if (Monitor.MULTI_BUFFERING <= 0)
        return;
    BufferCapabilities desiredCaps = new BufferCapabilities(new ImageCapabilities(true), new ImageCapabilities(true), Monitor.PAGE_FLIPPING ? FlipContents.BACKGROUND : null);
    Class<?> extBufCapClass = null;
    try {
        // Creates ExtendedBufferCapabilities via reflection to avoid problems with AccessControl
        extBufCapClass = Class.forName("sun.java2d.pipe.hw.ExtendedBufferCapabilities");
