Convert IplImage to byte array or IplImage to Bitmap in JavaCV - Android Java

Hi techies,

Now iam gonna share a wonderful and efficient way on "How to convert IplImage to byte array in JavaCV" with pure java code.

How to convert IplImage to Android Bitmap

public static Bitmap IplImageToBitmap(IplImage src) {
Bitmap bm=null;
   int width = src.width();
   int height = src.height();
// Unfortunately cvCvtColor will not let us convert in place, so we need to create a new IplImage with matching dimensions.
IplImage frame2 = IplImage.create(width, height, opencv_core.IPL_DEPTH_8U, 4);
opencv_imgproc.cvCvtColor(src, frame2, opencv_imgproc.CV_BGR2RGBA);
                   // Now we make an Android Bitmap with matching size ... Nb. at this point we functionally have 3 buffers == image size. Watch your memory usage!
bm = Bitmap.createBitmap(frame2.width(), frame2.height(), Bitmap.Config.ARGB_8888);
bm.copyPixelsFromBuffer(frame2.getByteBuffer());
//src.release();
frame2.release();
ByteArrayOutputStream stream = new ByteArrayOutputStream();
bm.compress(Bitmap.CompressFormat.PNG, 100, stream);
byte[] byteArray = stream.toByteArray();
return bm;
}

How to convert IplImage to byte[]

public static byte[] IplImageToByteArray(IplImage src) {
Bitmap bm=null;
    int width = src.width();
    int height = src.height();
 // Unfortunately cvCvtColor will not let us convert in place, so we need to create a new IplImage with matching dimensions.
  IplImage frame2 = IplImage.create(width, height, opencv_core.IPL_DEPTH_8U, 4);
  opencv_imgproc.cvCvtColor(src, frame2, opencv_imgproc.CV_BGR2RGBA);
                    // Now we make an Android Bitmap with matching size ... Nb. at this point we functionally have 3 buffers == image size. Watch your memory usage!
  bm = Bitmap.createBitmap(frame2.width(), frame2.height(), Bitmap.Config.ARGB_8888);
  bm.copyPixelsFromBuffer(frame2.getByteBuffer());
  //src.release();
  frame2.release();
  ByteArrayOutputStream stream = new ByteArrayOutputStream();
  bm.compress(Bitmap.CompressFormat.PNG, 100, stream);
  return stream.toByteArray();
}
