r - R 官员包：哪个布局属性确定了唯一标识占位符的正确索引？

问题描述

根据官员包裹文件：

当幻灯片布局中的类型不是唯一的时，将使用索引

但是，我找不到任何信息来识别占位符的哪个属性决定了它的索引。

下面，我提供了一个示例输出layout_properties()。

   master_name   name type id            ph_label     offx      offy       cx        cy
148      master layout body 14  Text Placeholder 4 7.500000 0.9791667 2.500000 0.5000000
150      master layout body 13 Text Placeholder 16 8.333333 1.6458333 1.416667 1.0000000
151      master layout body 12 Text Placeholder 13 1.583333 5.1458333 5.916667 0.4791667

我看到三种可能性可以确定每个文本占位符的正确索引值。

  1. 按列排名id。例如，从顶部开始，索引 = 3, 2, 1
  2. 按列中的数值排名ph_label。索引 = 1、3、2
  3. 按行顺序排列。索引 = 1、2、3

编辑

对于未来的用户，决定正确索引的是行顺序。

有趣的是，行顺序最初是我的猜测，但我发现该规则有一些例外。这些异常的原因实际上是我的本地计算机上的布局属性输出与我闪亮的服务器上的输出不同，即使它是完全相同的代码和完全相同的模板文件。现在为什么会发生这种情况？...我不知道。

解决方案

据我了解，索引是用户为幻灯片上的位置提供的，并layout_properties显示实际的幻灯片布局。我不相信那里的任何东西都对应于索引位置。

例如：

doc <- read_pptx() %>%
  add_slide(layout = "Two Content", master = "Office Theme") %>%
  ph_with_text(type = "body", str = "body (index 1) is text") %>% 
  ph_with_text(type = "body", str = "body (index 2) is also text")
print(doc, target = "C:/Foo/doc_1.pptx") # Since type is not unique, both are body, they get printed as if they are the same, at the same index position on top of each other.

> layout_properties(doc)
    master_name              name     type id                   ph_label      offx      offy       cx        cy
