Apache FOP 1.1 zCode QRCode

Question

好的我正在使用barcode4j-2.1和zxing-0.1.2在FOP 1.1中生成QR码。我目前通过将<prefer-renderer>true</prefer-renderer>添加到fop配置文件来实现正确工作的FOP 1.0。

barcode4j条形码正在工作，无论是否喜欢渲染器设置或不固定在barcode4j-2.1中修复。

我拥有所有必需的依赖关系：

• FOP-斑马线-0.1.2-JAR-与-dependencies.jar
• barcode4j-FOP-EXT-complete.jar
• saxon9he.jar - 使用XSLT 2.0 ...

这里是条形码片段：

<fo:block> 
    <fo:instream-foreign-object> 
    <qr:qr-code xmlns:qr="http://hobbut.ru/fop/qr-code/" 
        width="5cm" 
     message="TEST DATA" 
       correction="m" 
      encoding="UTF-8"> 
    </qr:qr-code> 
    </fo:instream-foreign-object> 
</fo:block> 

当试图转换喜欢渲染器似乎没有任何效果，我收到了错误：

SEVERE: Image not available. URI: (instream-object). Reason: org.apache.xmlgraphics.image.loader.ImageException: The file format is not supported. No ImagePreloader found for null (No context info available)

预先感谢任何帮助

您使用的xmlns：QR =“HTTP： //hobbut.ru/fop/qr-code/“，这与Barcode4J无关。似乎您计划使用比Barcode4J更多的其他FOP插件，但您最终将Barcode4J放入类路径而不是正确的插件。顺便说一下，Barcode4J在其CVS仓库的HEAD分支中集成了用于QR码生产的ZXing。
