代码来自官方文档，但是简单生成就是一行代码搞定
// get QR file from text using defaults
File file = QRCode.from("Hello World").file();
// get QR stream from text using defaults
ByteArrayOutputStream stream = QRCode.from("Hello World").stream();
// override the image type to be JPG
QRCode.from("Hello World").to(ImageType.JPG).file();
QRCode.from("Hello World").to(ImageType.JPG).stream();
// override image size to be 250x250
QRCode.from("Hello World").withSize(250, 250).file();
QRCode.from("Hello World").withSize(250, 250).stream();
// override size and image type
QRCode.from("Hello World").to(ImageType.GIF).withSize(250, 250).file();
QRCode.from("Hello World").to(ImageType.GIF).withSize(250, 250).stream();
// override default colors (black on white)
// notice that the color format is "0x(alpha: 1 byte)(RGB: 3 bytes)"
// so in the example below it's red for foreground and yellowish for background, both 100% alpha (FF).
QRCode.from("Hello World").withColor(0xFFFF0000, 0xFFFFFFAA).file();
// supply own outputstream
QRCode.from("Hello World").to(ImageType.PNG).writeTo(outputStream);
// supply own file name
QRCode.from("Hello World").file("QRCode");
// supply charset hint to ZXING
QRCode.from("Hello World").withCharset("UTF-8");
// supply error correction level hint to ZXING
QRCode.from("Hello World").withErrorCorrection(ErrorCorrectionLevel.L);
// supply any hint to ZXING
QRCode.from("Hello World").withHint(EncodeHintType.CHARACTER_SET, "UTF-8");
// encode contact data as vcard using defaults
VCard johnDoe = new VCard("John Doe")
.setEmail("john.doe@example.org")
.setAddress("John Doe Street 1, 5678 Doestown")
.setTitle("Mister")
.setCompany("John Doe Inc.")
.setPhoneNumber("1234")
.setWebsite("www.example.org");
QRCode.from(johnDoe).file();
// encode email data
EMail email = new EMail("John.Doe@example.org");
QRCode.from(email).file();
// encode mms data
MMS mms = new MMS("Hello World");
QRCode.from(mms).file();
// encode sms data
SMS sms = new SMS("Hello World");
QRCode.from(sms).file();
// encode MeCard data
MeCard johnDoe = new MeCard("John Doe");
johnDoe.setEmail("john.doe@example.org");
johnDoe.setAddress("John Doe Street 1, 5678 Doestown");
johnDoe.setTelephone("1234");
QRCode.from(johnDoe).file();
// if using special characters don't forget to supply the encoding
VCard johnSpecial = new VCard("Jöhn Dɵe")
.setAddress("ëåäöƞ Sträät 1, 1234 Döestüwn");
QRCode.from(johnSpecial).withCharset("UTF-8").file();
