Usage

From source file:Main.java

public static String writeBitmap(byte[] data, int cameraDegree, Rect rect, Rect willTransformRect)
        throws IOException {
    File file = new File(Environment.getExternalStorageDirectory() + "/bookclip/");
    file.mkdir();//from  ww w  . j a  v  a 2  s  . c om
    String bitmapPath = file.getPath() + "/" + System.currentTimeMillis() + ".png";

    // bitmap rotation, scaling, crop
    BitmapFactory.Options option = new BitmapFactory.Options();
    option.inSampleSize = 2;
    Bitmap bitmap = BitmapFactory.decodeByteArray(data, 0, data.length, option);
    Matrix bitmapMatrix = new Matrix();
    bitmapMatrix.setRotate(cameraDegree);
    int x = rect.left, y = rect.top, width = rect.right - rect.left, height = rect.bottom - rect.top;
    Bitmap rotateBitmap = Bitmap.createBitmap(bitmap, 0, 0, bitmap.getWidth(), bitmap.getHeight(), bitmapMatrix,
            false);
    // bitmap recycle
    bitmap.recycle();

    Bitmap scaledBitmap = Bitmap.createScaledBitmap(rotateBitmap, willTransformRect.right,
            willTransformRect.bottom - willTransformRect.top, false);
