Example 8 with MultiFormatWriter

use of com.google.zxing.MultiFormatWriter in project QRCode by 5peak2me.

the class MainActivity method Create2DCode.

    // 生成二维矩阵,编码时指定大小,不要生成了图片以后再进行缩放,这样会模糊导致识别失败
    BitMatrix matrix = new MultiFormatWriter().encode(str, BarcodeFormat.QR_CODE, 480, 480, hints);
    int width = matrix.getWidth();
    int height = matrix.getHeight();
