I'm doing a facial parameter software that doctors could use to extract
angles and ratios of the nose. This is what i have so far, I even tried to
rotate the picture and still the returned image is distorted.
Code:
Bitmap b = BitmapFactory.decodeFile(getIntent().getStringExtra("imagePath"
));
float rotation = (float) this.getIntent().getFloatExtra("resource",
0);
DisplayMetrics displayMetrics = new DisplayMetrics();
WindowManager wm = (WindowManager)
getApplicationContext().getSystemService(Context.WINDOW_SERVICE); // the
results will be higher than using the activity context object or the
getWindowManager() shortcut
wm.getDefaultDisplay().getMetrics(displayMetrics);
int screenWidth = displayMetrics.widthPixels;
int screenHeight = displayMetrics.heightPixels;
Matrix matrix = new Matrix();
// float rotation =
PhotoTaker.rotationForImage(this.getApplicationContext(), uri);
if (rotation != 0f) {
matrix.preRotate(rotation);
}
Bitmap scaled = Bitmap.createBitmap(b, 0, 0, b.getWidth(),
b.getHeight(), matrix, true);
//b.createScaledBitmap(b, 320, 480, true);
n.setBackGround(scaled,screenWidth,screenHeight);
//preview.setImageBitmap(b);
setContentView(n);
