Unable to create PPTX from default PPTX Reference Document using Markdown

Unable to create PPTX from default PPTX Reference Document using Markdown

[Phillip Dudley]

[-- Attachment #1.1: Type: text/plain, Size: 1386 bytes --]


I wanted to try making a PowerPoint using Pandoc and Markdown, but use a 
template that had some images already in the template. I saw that you can 
generate a reference document by doing:

   - https://pandoc.org/MANUAL.html#options-affecting-specific-writers

The command:

    pandoc -o custom-reference.pptx --print-default-data-file reference.pptx

Then I added a background image to the first slide, saved the 
custom-reference. I then tried to build the new PPTX using

    #cat Makefile
    .PHONY: build

    build:
        pandoc \
            --reference-doc custom-pptx-reference.pptx \
            --output slides.pptx \
            content.md

I then get the following errors:

filbot@pop-os ~/D/D/L/PPTX> make build
pandoc \
    --reference-doc custom-pptx-refernce.pptx \
    --output slides.pptx \
    content.md
Could not find shape for Powerpoint content
make: *** [Makefile:4: build] Error 63


Am I misinterpreting the documentation on how to use this?

Generally speaking, the only modifications that are going to work
in a reference.docx or pptx are the changes to the styles
as described in the manual.  If you add images, notes, etc.,
you're likely to get a corrupted file.

I guess I'm not seeing on the documentation where it is called out how to 
modify those styles? Some GitHub issues I saw said to unzip the PPTX and 
then look for some XML file that called out the four styles called out in 
the documentation. However, that didn't make sense to me. 

Does anyone have any examples of how to successfully, and clearly 
explained, do this?

I did some work on this late last year: from memory you are able to use any 
pptx (within reason, as indicated by the manual) and modify styles / slide 
templates appropriately. Note that you need to modify Slide Masters, not 
the slides themselves (again, from memory...)

For **table styles**, however, there does not exist an interface within 
PowerPoint to modify these at the style level. You need to manually modify 
the XML within your template, see 
http://www.brandwares.com/bestpractices/2015/07/xml-hacking-custom-table-styles/ 
for more information. It *does* work, and table styles are used when tables 
are generated within a slide, however even Microsoft's Office XML validator 
is unable to tell you if your table styles are correct; you need to try and 
open the document in PowerPoint and see if you get any errors.

That blog's formatting is to be desired. I'll give this a read through and 
see if I can figure out how to edit the Master Slides in LibreOffice 
Impress. Will report back with findings.
