示例1: grab
import org.andengine.opengl.util.GLHelper; //导入方法依赖的package包/类
private static Bitmap grab(final int pGrabX, final int pGrabY, final int pGrabWidth, final int pGrabHeight) {
final int[] pixelsRGBA_8888 = new int[pGrabWidth * pGrabHeight];
final IntBuffer pixelsRGBA_8888_Buffer = IntBuffer.wrap(pixelsRGBA_8888);
