使用 ReportLab 显示页数 [英] Showing page count with ReportLab

问题描述

我正在尝试向使用 ReportLab 制作的报告添加一个简单的第 x 页".我发现 这篇关于它的旧帖子，但也许六年后出现了更直接的东西?^^;
我也找到了 这个食谱，但是当我使用它时，生成的 PDF 缺少图像..

I'm trying to add a simple "page x of y" to a report made with ReportLab.. I found this old post about it, but maybe six years later something more straightforward has emerged? ^^;
I found this recipe too, but when I use it, the resulting PDF is missing the images..

推荐答案

我能够从 ActiveState 实施 NumberedCanvas 方法.这很容易做到，并且没有改变我现有的代码.我所要做的就是在构建我的文档时添加那个 NumberedCanvas 类并添加 canvasmaker 属性.我还更改了x of y"显示位置的测量值:

I was able to implement the NumberedCanvas approach from ActiveState. It was very easy to do and did not change much of my existing code. All I had to do was add that NumberedCanvas class and add the canvasmaker attribute when building my doc. I also changed the measurements of where the "x of y" was displayed:

self.doc.build(pdf)

变成了

self.doc.build(pdf, canvasmaker=NumberedCanvas) 

doc 是 BaseDocTemplate，pdf 是我的可流动元素列表.

doc is a BaseDocTemplate and pdf is my list of flowable elements.
