Capturing Camera image with Overlay Content

Hi Experts,

I have used the code below to capture screenshot in other AR apps.

public Bitmap SavePixels(int x, int y, int w, int h, GL10 gl)

{

int b[]=newint[w*(y+h)];

int bt[]=newint[w*h];

IntBuffer ib=IntBuffer.wrap(b);

ib.position(0);

int image_size = w * h * BYTES_PER_PIXEL;

ByteBuffer mBuffer = ByteBuffer.allocate(image_size);

//gl.glReadPixels(x, 0, w, y+h, GLES20.GL_RGBA, GLES20.GL_UNSIGNED_BYTE, ib);

GLES20.glReadPixels(x, 0, w, y+h,

DominoesRenderer.PIXEL_FORMAT,

DominoesRenderer.PIXEL_TYPE,

mBuffer);

try {

BufferedWriter mImageListWriter = null;

        String filename = "/sdcard/PictAR/ScreenCapture/Save.png";

File image_list = new File(filename);

image_list.delete();

mImageListWriter = new BufferedWriter(new FileWriter(image_list));

mImageListWriter.write(filename);

mImageListWriter.newLine();

FileOutputStream fos = new FileOutputStream(filename);

fos.write(mBuffer.array());

fos.close();

} catch (java.io.IOException e) {

Log.e("DominoesRenderer", e.getMessage(), e);

}

for(int i=0, k=0; i<h; i++, k++)

        {//remember, that OpenGL bitmap is incompatible with Android bitmap

            //and so, some correction need.

for(int j=0; j<w; j++)

{

int pix=b[i*w+j];

int pb=(pix>>16)&0xff;

int pr=(pix<<16)&0x00ff0000;

int pix1=(pix&0xff00ff00) | pr | pb;

bt[(h-k-1)*w+j]=pix1;

}

}

Bitmap sb=Bitmap.createBitmap(bt, w, h, Bitmap.Config.ARGB_8888);

return sb;

    }

 However, when I use the same in Dominoes sample of vuforia-sdk-android-1-5-9, it returns only the camera image. Not the AR content drawn on it. I call this method from onDrawFrame of the DominoesRenderer class.

Please help.

Best regards,

lucky
