Android Studio Java : Resize Bitmap Capture and Encode to base64 Image

Caranya dengan menggunakan function / method :

function untuk meresize :

public static Bitmap scaleBitmap(Bitmap bitmap, int wantedWidth, int wantedHeight) {
    Bitmap output = Bitmap.createBitmap(wantedWidth, wantedHeight, Bitmap.Config.ARGB_8888);
    Canvas canvas = new Canvas(output);
    Matrix m = new Matrix();
    m.setScale((float) wantedWidth / bitmap.getWidth(), (float) wantedHeight / bitmap.getHeight());
    canvas.drawBitmap(bitmap, m, new Paint());
    return output;
}

function untuk mendecode Bitmap :

private String encodeImage64(Bitmap bm)
{
    ByteArrayOutputStream baos = new ByteArrayOutputStream();
    bm.compress(Bitmap.CompressFormat.JPEG,100,baos);
    byte[] b = baos.toByteArray();
    String encImage = Base64.encodeToString(b, Base64.DEFAULT);

    return encImage;
}

Contoh Penggunaan :

Bitmap fotokk=BitmapFactory.decodeFile(curentPhotopathfotokk);
Bitmap imgresizekk=scaleBitmap(fotokk, 800, 400);
String convertfotokk=encodeImage64(imgresizekk);
