类 DefaultQrCodeWriterQrCode

java.lang.Object

cn.patterncat.qrcode.core.writer.DefaultQrCodeWriterQrCode

所有已实现的接口:

QrCodeMatrixWriter

直接已知子类:

StrictQuietZoneWriterQrCode

public class DefaultQrCodeWriterQrCode
extends Object
implements QrCodeMatrixWriter

从com.google.zxing.qrcode.QRCodeWriter拷贝基本方法过来 由于原始类是final的,不好扩展,这里扩展一份修改renderResult方法修饰符方便子类重写 zxing版本升级的时候,注意下这个类的改动 Created by patterncat on 2017-10-27.

encode

public BitMatrixInfo encode(String contents,
                            com.google.zxing.BarcodeFormat format,
                            int width,
                            int height)
                     throws com.google.zxing.WriterException

从接口复制的说明: QrCodeMatrixWriter

Encode a barcode using the default settings.

指定者:

encode 在接口中 QrCodeMatrixWriter

参数:

contents - The contents to encode in the barcode

format - The barcode format to generate

width - The preferred width in pixels

height - The preferred height in pixels

返回:

BitMatrix representing encoded barcode image

抛出:

com.google.zxing.WriterException - if contents cannot be encoded legally in a format

encode

public BitMatrixInfo encode(String contents,
                            com.google.zxing.BarcodeFormat format,

                            int height,
                            Map<com.google.zxing.EncodeHintType,?> hints)
                     throws com.google.zxing.WriterException

指定者:

encode 在接口中 QrCodeMatrixWriter

参数:

contents - The contents to encode in the barcode

format - The barcode format to generate

width - The preferred width in pixels

height - The preferred height in pixels

hints - Additional parameters to supply to the encoder

返回:

BitMatrix representing encoded barcode image

抛出:

com.google.zxing.WriterException - if contents cannot be encoded legally in a format
