XSL-FO背景图像损坏生成的pdf

xsl-fo pdf-generation xslt xml

cico_dev · 技术社区 · 8 年前

我正在从下面的xsl文档生成PDF。我试图添加一个背景图像来覆盖整个生成的pdf,但当我包含 <fo: block-container> 第12行。是否有其他方法可以生成背景图像,或者我在这里做了不正确的事情?

我还尝试使用 <fo:external-graphic> 它确实显示了图像,但在顶部留下了一个边界(我认为这是之前的区域)。但这只适用于托管图像url,而不适用于本地存储的图像,这不是问题,但我发现有点奇怪。

<fo:block text-align="center" display-align="before"> <fo:external-graphic top="-20mm" bottom="-20mm" content-width="210mm" height="150mm" src="url()"> </fo:external-graphic> </fo:block>

通过添加 <fo:block-container> 围绕内容,我拉了学生姓名和学校名称等。完整代码如下
