Scenario: a task pane add-in displays a list of objects that represent content that can be added to a slide as a content add-in instances.
Allowing the instantiation of a content add-in programmatically would facilitate creation of great user experiences.

Hello,

I would like to convert selected Add-In slide images to an image. For example to base64 or png format.

Currently the JavaScript Api doesn't support this.

For an old project I used the following method to get this done in a VSTO Add-In:

    public string SlideToImage(Slide slide, string filePath)

    {

        // Store images in the given path with slide name e.g. C:\Users\BramR\AppData\Local\Temp\2\slide_afbeeldingen.jpg

        var path = $"{filePath}\\{slide.Name}.jpg";

        slide.Export(path, "PNG", 1024, 768);

        return path;

    }

Is there a way I could do this with the new Office Add-In generation?

Regards,
Bram

Presentation.SaveCopyAs fails when trying to save to the local OneDrive folder. Steps to reproduce (tested with 16.0.11001 and 16.0.10730):

VBA:
ActivePresentation.SaveCopyAs Environ("userprofile") & "\OneDrive\OneDriveSaveCopyAsTest.pptx"
This does not give an error, but does not save the copy.

C#:
ActivePresentation.SaveCopyAs(Environment.ExpandEnvironmentVariables(@"%userprofile%\OneDrive\OneDriveSaveCopyAsTest.pptx"));
This throws a COMException with HRESULT 0x80CD1001.

To extend PowerPoint with additional functionality and also add a new content type, we currently need to develop, package and deploy two add-ins, and task pane add-in and a content add-in. And the user needs to install two add-ins.
To improve developer/vendor and user experience it would be really helpful if at least two add-ins could be packaged, shipped, marketed and installed as a unit that can be discovered and installed in one step.

Presently there is no way to insert hyperlink to the powerpoint slides using the office JS. So please add ability to insert hyperlink to Powerpoint slides

Occasionally, when a presentation is opened while a modal (add-in) dialog is open, PowerPoint seems to get into an infinite loop reading the following registry value:
HKEYCURRENTUSER\Software\Microsoft\Office\16.0\Common\Identity\DisableADALatopWAMOverride

PowerPoint does not show as "Not responding" but effectively it is not responding to any clicks.

We have only seen this behavior on machines where DisableADALatopWAMOverride was set to 1. This cannot reliably be reproduced but happens on different machines for different users. All of this seems to be related to Office 365 authentication.

As like the Selection.Range.InsertXMl I need the option in powerpoint also. It will be helpful for adding contents using openxml.

I have a document with several fields the contents of which changes from project to project. Instead of opening this document in PowerPoint and running search/replace for each field, with a lot of keyboard/mouse input, I would like to be able to run a utility from command line, which would do it for me. For text files I could do it easily in Linux using sed, awk, etc. I need to be able to do the same for Word and PowerPoint files

Add support for the Add-In to create a new slide in the presentation. A possible use case would be to support the ability for an add-in to insert template marketing slides. A sales person needs to create a new presentation. The add-in pulls the latest marketing slide from a repository and adds them to the presentation ensuring that the sales person is always using the latest slides

I would like to be able to provide an add-in that could insert slides into a presentation. This is a similar concept to the Word Clause library. To provide maximum flexibility to the dev I would suggest using the Ooxml coercionType. Both Get and Set would be ideal

This is what I posted in forum as
https://social.msdn.microsoft.com/Forums/en-US/bf48b450-6ee4-408b-a441-a53b23c75346/failing-to-insert-a-large-image-into-powerpoint-slides-using-setselecteddataasync-in-officejs?forum=appsforoffice

It seems this is a limitation or bug. We are using setSelectedDataAsync with base64 encoding to copy the image into slide. but the image is corrupted if the image size is relatively huge (like over 5MB). The same code works with both Word and Excel. I guess something went wrong with PowerPoint.

Currently if an add-in relies upon being able to read and write Custom XML Parts, it can only do it in Word (and coming in Excel JS 1.3). It would be great to see this functionality appear in PowerPoint so that add-ins can be created that interact with data stored in Custom XML Parts.

getSelectedDataAsync only return text string (if there is text in selected shape). Would be great to return more info of selected shape, perhaps in OOXML/HTML form, or at least a shape ID.

Lot of Add-ins developers wants to create extend Add-in with adding same content to slides functionality(more, than images or text, that is allowed by setSelectedDataAsync method).

So they have to use Content Add-inns, and user have to add them to slides several times (for examle vote widgets of Mentimeter app.)
Its very unconvinient!

Please provide us extended the functionality of adding web pages to slides

Make it possible to use setSelectedDataAsync with data type “HTML” and “Office Open XML” in PowerPoint. Currently it is only Word that can use data type “HTML” and “Office Open XML”.

In my testing of content add-ins for Office I have found that the "Send to back/Bring to front" z-ordering does not work between the add-in component and other content in the slide. The add-in content is always in front of "native" content in the slide in the z-order. The z-ordering works between add-in content items. This means that you are not able to mix add-in content and native content in the slide - e.g. you can't add a text block over the top of an add-in element.

Extend Javascript API for Powerpoint to add and edit bindings as in Word and Excel.
