- drawQRCode:
Draw Base64 QR code
. - typeNumber:
QR code type
,the default value is 4, and the optional values are 1~40. 1 is 2121, 2 is 2525, 3 is 3333, 4 is 4141, and 40 is a 177*177 matrix. - errorCorrectLevel:
QR code error tolerance rate
, the default value is 'M', and the optional values are 'L', 'M', 'Q', and 'H'. L: 7%, M: 15%, Q: 25%, H: 30% error tolerance (errors can be corrected). The higher the error tolerance, the less likely the QR code is to be damaged, but the less likely it is to be recognized. - size:
QR code image size
, the default value is 300. - backgroundColor:
QR code background color
, the default value is '#ffffff'. - foregroundColor:

二维码类型
,默认值为4,可选值为1~40。1为2121,2为2525,3为3333,4为4141,40为177*177的矩阵。 - errorCorrectLevel:
二维码容错率
,默认值为'M',可选值为'L'、'M'、'Q'、'H'。 L: 7%, M: 15%, Q: 25%, H: 30% 容错率(错误能被纠正)。容错率越高,二维码越不易损坏,但越不易识别。 - size:
