OKバーコード4j-2.1とzxing-0.1.2を使用してFOP1.1でQRコードを生成する際に問題が発生しました。<prefer-renderer>true</prefer-renderer>現在、fop構成ファイルに追加することで、FOP1.0の実装が正しく機能しています。
バーコード4jバーコードは、優先レンダラーが設定されているかどうかに関係なく機能します。これは、barcode4j-2.1で修正されています。
私はすべての必要な依存関係を持っています：
- fop-zxing-0.1.2-jar-with-dependencies.jar
- バーコード4j-fop-ext-complete.jar
- saxon9he.jar-xslt2.0に使用..。
バーコードスニペットは次のとおりです。
<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>
優先レンダラーを変換しようとしても効果がないように見える場合、次のエラーが発生します。
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)
