Public API Changes

New elements have been added into Aspose.Slides.LoadFormat enumeration

Aspose.Slides.LoadFormat enumeration has been extended with new elements: Potx, Pptm, Ppsm, Potm.

New methods ReadDocumentProperties, UpdateDocumentProperties, and WriteBindedPresentation have been added to IPresentationInfo, logic of the IDocumentProperties.LastSavedTime property setter has been changed

The two new methods ReadDocumentProperties and UpdateDocumentProperties have been added to IPresentationInfo interface. They provide a quick access to document properties and allow to change and update properties without loading a whole presentation.

The typical scenario load the properties, change some value and update the document can be implemented in the following way:

// read the info of presentation
IPresentationInfo info = PresentationFactory.Instance.GetPresentationInfo("presentation.pptx");

// obtain the current properties
IDocumentProperties props = info.ReadDocumentProperties();

// set the new values of Author and Title fields
props.Author = "New Author";
props.Title = "New Title";

// update the presentation with a new values
info.UpdateDocumentProperties(props);
info.WriteBindedPresentation("updated_presentation.pptx");

There’s an another way to use properties of a particular presentation as a template to update properties in other presentations:

private void UpdateByTemplate()
{
  DocumentProperties template;
  IPresentationInfo info = PresentationFactory.Instance.GetPresentationInfo("template.pptx");
  template = (DocumentProperties)info.ReadDocumentProperties();

  template.Author = "Template Author";
  template.Title = "Template Title";
  template.Category = "Template Category";
  template.Keywords = "Keyword1, Keyword2, Keyword3";
  template.Company = "Our Company";
  template.Comments = "Created from template";
  template.ContentType = "Template Content";
  template.Subject = "Template Subject";

  UpdateByTemplate("doc1.pptx", template);
  UpdateByTemplate("doc2.odp", template);
  UpdateByTemplate("doc3.ppt", template);
}

private void UpdateByTemplate(string path, IDocumentProperties template)
{
    IPresentationInfo toUpdate = PresentationFactory.Instance.GetPresentationInfo(path);
    toUpdate.UpdateDocumentProperties(template);
    toUpdate.WriteBindedPresentation(path);
}

Or a new template can be created from scratch and then used to update multiple presentations:

private void UpdateByTemplate()
{
    DocumentProperties template = new DocumentProperties()
    {
        Author = "Template Author",
        Title = "Template Title",
        Category = "Template Category",
        Keywords = "Keyword1, Keyword2, Keyword3",
        Company = "Our Company",
        Comments = "Created from template",
        ContentType = "Template Content",
        Subject = "Template Subject"
    };

    UpdateByTemplate("doc1.pptx", template);
    UpdateByTemplate("doc2.odp", template);
    UpdateByTemplate("doc3.ppt", template);
}

private void UpdateByTemplate(string path, IDocumentProperties template)
{
    IPresentationInfo toUpdate = PresentationFactory.Instance.GetPresentationInfo(path);
    toUpdate.UpdateDocumentProperties(template);
    toUpdate.WriteBindedPresentation(path);
}

Also, CreatedTime and LastPrinted properties of IDocumentProperties have been made readable and writable. IDocumentProperties.LastSavedTime has made writable too, but only if it is created as a standalone object or returned by IPresentationInfo.ReadDocumentProperties() method (not if it is returned by IPresentation.DocumentProperties property).
