从fop-0.95升级到fop-2.3
我是XSLT FO世界的新手，遇到了一个问题。我的XSLT与fop-0.95处理器配合使用并生成PDF，但是升级到fop-2.3之后，它使我的第一页空白，并从第二页开始PDF正文（我的PDF的标题出现了在第一页上可以）。
我弄清楚问题出在哪里，这是因为我在“ fo：layout-master-set”（“ fo：layout-master-set”）中的“ fo：region-body”标签中将margin-top值设置为3英寸请参阅截图）。我必须将margin-top从3英寸更改为2.5英寸，以使PDF主体看起来像使用fop-0.95时的样子。

有人知道为什么会这样吗？
我有多个具有相同布局的PDF，因此如果我需要升级到fop-2.3，是否必须对所有PDF进行此更改？
编辑-1.感谢您的评论和回答。抱歉，我花了一段时间才回复，因为我正在努力批准发布此xslt。
2。我编辑了xslt，因为它太大而无法遵守该帖子的字数限制。但是它仍然具有所有重要部分，例如PDF正文的开头等。
1 个答案:
答案 0 :(得分：0)
对不起，但找出为什么同一软件的不同版本之间有所不同的最佳方法是浏览自较旧版本以来的发行说明。
FOP在其网站上有发行说明。当我确认这一点时，我在https://xmlgraphics.apache.org/fop/1.0/changes_1.0.html上找到了它，这可能就是您想要的：
启用宽松验证时，允许非零边框和页面区域上的填充。由LF承诺。
如果这是原因，那么解决方法是从margin-top中删除fo:simple-page-master。否则，恐怕还有很多发行说明供您浏览。
