我正在通过Apache FOP，java库使用XML和XSL生成pdf。
我不知道如何显示每页（甚至单页...）的背景图像。
背景必须放置在文本的底部，并且要覆盖几乎所有页面（不包括边距）。
我搜索的结果不理想，谢谢。

您可以在fo:region-body上指定背景图像。请参阅https://www.w3.org/TR/xsl11/#fo_region-body，其中“ 7.8通用边框，填充和背景属性”（https://www.w3.org/TR/xsl11/#common-border-padding-and-background-properties）包括background-image（https://www.w3.org/TR/xsl11/#background-image）。
