Public API Changes
Support for the Grid and Guides properties
New methods ‘get_GridSpacing()’ and ‘set_GridSpacing()’ has been added to the ‘IViewProperties’ interface and the ‘ViewProperties’ class:
float get_GridSpacing() const;
void set_GridSpacing(float value)
A new class ‘DrawingGuide’ and its corresponding interface ‘IDrawingGuide’ have been added. These class and interface are used to define the settings for drawing guides.
A new class ‘DrawingGuidesCollection’ and its corresponding interface ‘IDrawingGuidesCollection’ have been added to store adjustable drawing guides.
A new method ‘get_DrawingGuides()’ has been added to the ‘ICommonSlideViewProperties’ interface and the ‘CommonSlideViewProperties’ class. The following code sample shows how to add the new vertical and horizontal drawing guides to a PowerPoint presentation:
System::SharedPtr<Presentation> pres = System::MakeObject<Presentation>();
System::Drawing::SizeF slideSize = pres->get_SlideSize()->get_Size();
System::SharedPtr<IDrawingGuidesCollection> guides = pres->get_ViewProperties()->get_SlideViewProperties()->get_DrawingGuides();
// Adding the new vertical drawing guide to the right of the slide center
guides->Add(Orientation::Vertical, slideSize.get_Width() / 2 + 12.5f);
// Adding the new horizontal drawing guide below the slide center
guides->Add(Orientation::Horizontal, slideSize.get_Height() / 2 + 12.5f);
pres->Save(u"DrawingGuides_out.pptx", SaveFormat::Pptx);
The Grid and Guides properties allow you to configure the spacing between grid lines in the background of your document. The following code sample shows how to set the grid spacing to 72 points (1 inch) and save the PowerPoint presentation.
System::SharedPtr<Presentation> pres = System::MakeObject<Presentation>();
pres->get_ViewProperties()->set_GridSpacing(72.0f);
pres->Save(u"GridSpacing_out.pptx", SaveFormat::Pptx);
Also you can add or change adjustable drawing guides. The following code sample shows how to add the new vertical and horizontal drawing guides to a PowerPoint presentation:
System::SharedPtr<Presentation> pres = System::MakeObject<Presentation>();
System::Drawing::SizeF slideSize = pres->get_SlideSize()->get_Size();
System::SharedPtr<IDrawingGuidesCollection> guides = pres->get_ViewProperties()->get_SlideViewProperties()->get_DrawingGuides();
// Adding the new vertical drawing guide to the right of the slide center
guides->Add(Orientation::Vertical, slideSize.get_Width() / 2 + 12.5f);
// Adding the new horizontal drawing guide below the slide center
guides->Add(Orientation::Horizontal, slideSize.get_Height() / 2 + 12.5f);
pres->Save(u"DrawingGuides_out.pptx", SaveFormat::Pptx);
A new method ‘get_DrawingGuide()’ has been added to the ‘ICommonSlideViewProperties’ interface and the ‘CommonSlideViewProperties’ class to extract drawing guide by index from collection.
System::SharedPtr<Presentation> pres = System::MakeObject<Presentation>();
System::Drawing::SizeF slideSize = pres->get_SlideSize()->get_Size();
// First way
System::SharedPtr<IDrawingGuidesCollection> guides = pres->get_ViewProperties()->get_SlideViewProperties()->get_DrawingGuides();
System::SharedPtr<IDrawingGuide> guide = guides->idx_get(0);
// Second way
System::SharedPtr<IDrawingGuide> firstGuide = pres->get_ViewProperties()->get_SlideViewProperties()->get_DrawingGuide(0);
