As the title says: I would like to be able to specify id (as an HTML attribute) for (some) IShapes when they are converted to HTML. Is it possible? Like in:
<rect id=“my_id” … />

@RadekK,
Thank you for your patience. Please try using the IHtmlFormattingController to wrap the shapes and add your attributes as follows:

auto presentation = MakeObject<Presentation>(u"sample.pptx");

auto htmlFormatter = HtmlFormatter::CreateCustomFormatter(MakeObject<CustomFormattingController>());
    
auto htmlOptions = System::MakeObject<HtmlOptions>();
htmlOptions->set_HtmlFormatter(htmlFormatter);
          
presentation->Save(u"output.html", SaveFormat::Html, htmlOptions);
presentation->Dispose();

class CustomFormattingController : public IHtmlFormattingController
{
public:
    void WriteDocumentStart(SharedPtr<IHtmlGenerator> generator, SharedPtr<IPresentation> presentation) override {}
    void WriteDocumentEnd(SharedPtr<IHtmlGenerator> generator, SharedPtr<IPresentation> presentation) override {}
    void WriteSlideStart(SharedPtr<IHtmlGenerator> generator, SharedPtr<ISlide> slide) override {}
    void WriteSlideEnd(SharedPtr<IHtmlGenerator> generator, SharedPtr<ISlide> slide) override {}

    void WriteShapeStart(SharedPtr<IHtmlGenerator> generator, SharedPtr<IShape> shape) override
    {
        String header = String::Format(ShapeHeader, ShapeId++);
        generator->AddHtml(header);
    }

    void WriteShapeEnd(SharedPtr<IHtmlGenerator> generator, SharedPtr<IShape> shape) override
    {
        generator->AddHtml(ShapeFooter);
    }

private:
    static const String ShapeHeader;
    static const String ShapeFooter;
    static int ShapeId;
};

const String CustomFormattingController::ShapeHeader = u"<div id=\"{0}\">";
const String CustomFormattingController::ShapeFooter = u"</div>";
int CustomFormattingController::ShapeId = 1;
