想要添加页眉和页脚来打印
我不需要将页眉和页脚添加回XPS文档 - 仅限于打印输出
我尝试实施DocumentPaginator但无法使尺寸或展示位置正常工作
与此footer to FlowDocument不同 我在那里使用FlowDocuments的解决方案就好了 Convert XAML Flow Document to XPS with Style
在FixedDocumentSequence上，大小来自文档（我猜）
例如，可以混合风景和肖像
我无法弄清楚如何勾选大小并为页眉和页脚腾出空间
我可以在上面盖章，但它在页面的顶部
景观页面被切断
当来自FixedDocumentSequence时，无法分配PageSize
如链接中所述，它是建议的页面大小
DocumentPage。尺寸为只读
即使我使用DocumentPaginator.GetPage加载页面时创建了我想要的大小的DocumentPage，那么大小也会被覆盖
更糟糕的是，DocumentPaginator似乎没有正确地意识到尺寸，因为它没有正确处理混合风景和肖像。风景是打印的肖像，只是在页面上运行。
