, I was able to put together something similar to your code which does not generate run-time exceptions; admittedly, I'm not familiar enough with this PDF feature to say whether the output actually achieves what you are trying to do:<fo:declarations>
<pdf:catalog xmlns:pdf="http://xmlgraphics.apache.org/fop/extensions/pdf">
<pdf:dictionary type="normal" key="ViewerPreferences">
<pdf:boolean key="DisplayDocTitle">true</pdf:boolean>
</pdf:dictionary>
</pdf:catalog>
</fo:declarations>
<pdf:dictionary type="Catalog">
,而是pdf:catalog
<pdf:entry key="..." type="...">
元素,但是每种可能的输入类型都有一个特定的元素:pdf:array
,pdf:boolean
,pdf:name
,pdf:number
,pdf:string
,...
- there is no
<pdf:dictionary type="Catalog">
, there ispdf:catalog
instead - there is not a single
<pdf:entry key="..." type="...">
element, but there is a specific element for each possible entry type:pdf:array
,pdf:boolean
,pdf:name
,pdf:number
,pdf:string
, ...
