在andengine屏幕捕捉，使倒挂镜像(Screen Capture in andengine g

在我的情况我没有使用RenderSurfaceView。 我想利用我的场景的屏幕截图。 但是，当我保存的屏幕截图它显示倒挂镜像。 无法理解什么即时做错了什么。

这里是我的代码

attachChild(screenCapture);

                    share_clicked = 1;

                    final int viewWidth = (int)camera.getWidth();
                    final int viewHeight = (int)camera.getHeight();

                    Log.d("camera width", "View width :" + viewWidth);
                    Log.d("camera height", "View height :" + viewHeight);


                    File direct = new File(
                            Environment.getExternalStorageDirectory()
                                    + "/Word");

                    if (!direct.exists()) {
                        if (direct.mkdir())
                            ; // directory is created;

                    }

                    screenCapture.capture(
                            viewWidth,
                            viewHeight,
                            direct.getAbsolutePath() + "/word"
                                    + System.currentTimeMillis() + ".png",

                            new IScreenCaptureCallback() {

                                public void onScreenCaptured(
                                        final String pFilePath) {
                                    activity
                                            .runOnUiThread(new Runnable() {

                                                public void run() {
                                                    Toast.makeText(
                                                            activity,
                                                            "Image Successfully saved to 'Word' folder in SD Card.",
                                                            Toast.LENGTH_SHORT)
                                                            .show();
                                                }
                                            });

                                }

                                public void onScreenCaptureFailed(
                                        final String pFilePath,
                                        final Exception pException) {


                                    activity.runOnUiThread(new Runnable() {

                                                public void run() {
                                                    Toast.makeText(
                                                            activity,
                                                            "Failed saving the image! Please check SD card.",
                                                            Toast.LENGTH_SHORT)
                                                            .show();
                                                }
                                            });
                                }
                            });

这将是一个很大的帮助，如果任何人都可以寻求这一点对我来说。 谢谢。

更新GLES2-AnchorCenter

AndEngine / SRC /组织/ andengine /实体/ UTIL / ScreenGrabber.java

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);

    // TODO Check availability of OpenGL and GLES20.GL_RGBA combinations that require less conversion operations.
    GLES20.glReadPixels(pGrabX, pGrabY, pGrabWidth, pGrabHeight, GLES20.GL_RGBA, GLES20.GL_UNSIGNED_BYTE, pixelsRGBA_8888_Buffer);

    /* Convert from RGBA_8888 (Which is actually ABGR as the whole buffer seems to be inverted) --> ARGB_8888. */
    final int[] pixelsARGB_8888 = GLHelper.convertRGBA_8888toARGB_8888(pixelsRGBA_8888);

    final int[] pixels = new int[pGrabWidth * pGrabHeight];

    for (int y = 0; y < pGrabHeight; y++) {
        for (int x = 0; x < pGrabWidth; x++) {
            pixels[x + ((pGrabHeight - y - 1) * pGrabWidth)] = pixelsARGB_8888[x + ((pGrabY + y) * pGrabWidth)];
        }
    }

    return Bitmap.createBitmap(pixels, pGrabWidth, pGrabHeight, Config.ARGB_8888);
}
