Integrate ShapeCrawler with OpenXML SDK

[ashahabov]

Hello,

if I understand correctly, the idea is to expose the underlying object of the Open XML SDK for updating. For example, by adding a new property IChart.SDKChartPart that holds the DocumentFormat.OpenXml.Packaging.ChartPart instance.

We've already practiced this, and we still have such properties in parts of the library, which should be removed.

The downside is that this completely breaks encapsulation, contradicting one of the main principles of the library, that states that all manipulations with the presentation should only be done via ShapeCrawler's objects. If an API is missing, we need to implement it🙂

Hi,

I understand, but at the moment there are quite a few things that SchapeCrawler is not doing yet.

FYI, the above (closing, saving, reopening) was a catastrophe.
I found out that non public members can be accessed this way, so this problem is resolved.

var sdkSlidePartField = slide.GetType().GetField("sdkSlidePart", BindingFlags.NonPublic | BindingFlags.Instance);
var slidePart = (SlidePart)sdkSlidePartField?.GetValue(slide);

And now I can continue with OpenXML SDK without any problem and get back to ShapeCrawler after i am done.

Maybe you're right 🤔, and we should temporarily give access to the underlying SDK objects, at least until the first stable 1.0 version that includes enough features.

Please provide (if you need) a list of the additional SDK objects besides Slide.SlidePart for the your above workflow. I will consider making them accessible.
