Placeholders visibility and ISO_IEC_29500-1_2011 standard

Ilya Y · #1 05-19-2012, 01:09 AM

Hello

I am trying to understand logic which is applied to placeholders and how this logic is connected with the ISO_IEC_29500-1_2011 standard.
It seems that, visible state of placeholders like header, footer, slide number and date have to be configured by “hf” property (19.3.1.25 hf (Header/Footer information for a slide master)) – but, I can not even find this tag in a pptx document. I have checked master slide (\ppt\slideMasters\slideMaster1.xml), layout slide (ppt\slideLayouts\slideLayout1.xml) and simple slide (\ppt\slides\slide1.xml) – but nothing((

My mind is exploding – please, can you describe how behavior of a placeholders (will be the placeholder shown on a slide or not) is defined by the 29500-1 standard???

For example: I going to add a slide based on a layout, I now, that there is no any “hf” tags in the master slide or layout, also I know that the layout has header, footer, page number and some custom placeholders. Which placeholders will be present on a just created slide???

Probably, there is better place for this question – any suggestion or
references will be appreciated.

Many thanks in advance.

So, I had similar discussion on the social.msdn.microsoft.com forum (http://social.msdn.microsoft.com/Forums/pl-PL/os_openXML-ecma/thread/0d435497-2028-4a43-bd62-abed4a69f471):
Here is quote:

Let s perform a little scenario, step by step:
1.Open or create a presentation by power point.
2.Remove all slides.
3.Remove all layouts.
4.Remove all shapes from the master page.
5.Add a “page number” placeholder to the master page. (let’s look inside the “ppt\slideMasters\slideMaster1.xml”, since this point, we have a shape (‘sp’) which is marked as page number placeholder ”ph type="sldNum"). There is no “hf” – but it is not a problem here because it can be omitted.
6.Add a layout. We will see the “page number” place holder and “Title” place holder. Open the “ppt\slideLayouts\slideLayout1.xml” file – there are two shapes which are marked as placeholders (ph type="sldNum” and ph type="title"). Again, there is no “hf” – and, again, it is not a problem. No magic here))).
7.Attention!!! The problem right now!!!!
8.Add a new slide. We will see ONLY the title placeholder. Inside the “ppt\slides\slide1.xml” we have ONLY one shape (marked as <ph type="title" …>).
Why we don’t have a shape for the "sldNum" placeholder? Why we don’t see it? There is no any “hf” –by default all placeholders should be visible.
Many thanks in advance.

Hi Ilya,
After doing some research on this, it appears that this is not a standards or implementation specific issue but a behaviour problem with PowerPoint (for example, see http://answers.microsoft.com/en-us/o...4-e53889782fc6). The Open Specifications and ISO standard are correct. Please post to the Office or Answers forum for help with PowerPoint behavior issues.

Now, I have only the question “Is it a bug or is it a feature”?
What if my chief says: “I want the same behavior” – should I follow to the actual Powerpoint behavior or this behavior will be changed soon in accordance to the standard 29500?

Don't know if it's a bug / feature but when you insert a new slide the normal default is NOT to show number / footer / date placeholders even if they are on the Master / layout.
