android steganography
- by poo123
Im doing steganography on android...my code is as below..
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
mBitmap = BitmapFactory.decodeResource(getResources(), R.drawable.src);
picw = mBitmap.getWidth();
pich = mBitmap.getHeight();
pix= new int[picw * pich];
mBitmap.getPixels(pix, 0, picw, 0, 0, picw, pich);
try {
FileOutputStream fos = super.openFileOutput("dest.png", MODE_WORLD_READABLE);
mBitmap.compress(CompressFormat.PNG, 100, fos);
fos.flush();
fos.close();
}catch (Exception e) {
tv.setText(e.getMessage());
}
but whenever i save source image with Bitmap.compress() method pix[0] value before and after compression changed..so i'm unable to extract original data...please help me
