Public API Changes

CreateTextFrameFormatEffective() method has been added to ITextFrame interface and TextFrame class

It returns an effective value of text frame format for a TextFrame object. The returned type is ITextFrameFormatEffective.

Interface Aspose.Slides.ITextFrameFormatEffective has been added

Represents effective values (formatting values with inheritance applied) of text frame format. It contains the following members: ITextStyleEffectiveData TextStyle — Returns effective text’s style. double MarginLeft — Returns the left margin (points) in a TextFrame. double MarginRight — Returns the right margin (points) in a TextFrame. double MarginTop — Returns the top margin (points) in a TextFrame. double MarginBottom — Returns the bottom margin (points) in a TextFrame. bool WrapText — Returns if text is wrapped at TextFrame’s margins. TextAnchorType AnchoringType — Returns vertical anchor text in a TextFrame. bool CenterText — Returns if text should be centered in box horizontally. TextVerticalType TextVerticalType — Returns text orientation. TextAutofitType AutofitType — Returns text autofit mode.

Interface Aspose.Slides.ITextStyleFormatEffective has been added

Represents effective values (formatting values with inheritance applied) of text style. It contains the following members:

IParagraphFormatEffectiveData GetLevel(int index) — Returns level of effective style. IParagraphFormatEffectiveData DefaultParagraphFormat — Returns effective default paragraph properties.

EmbeddedWoffFontsHtmlController and EmbeddedEotFontsHtmlController classed have been added to provide the functionality to embed WOFF and EOT fonts into generated HTML documents

The two new classes have been added to provide the functionality to embed WOFF and EOT fonts into generated HTML documents:

  • EmbeddedWoffFontsHtmlController
  • EmbeddedEotFontsHtmlController

Below there is an example of how to use the new EmbeddedWoffFontsHtmlController class to export HTML with embedded WOFF fonts:

using (Presentation pres = new Presentation("pres.pptx"))
  EmbeddedWoffFontsHtmlController controller = new EmbeddedWoffFontsHtmlController();
  HtmlOptions htmlOptions = new HtmlOptions
    HtmlFormatter = HtmlFormatter.CreateCustomFormatter(controller)
  pres.Save("pres.html", SaveFormat.Html, htmlOptions);

New methods have been added to FontsManager

The following new methods have been added to IFontsManager interface and FontsManager class: IFontData[] GetEmbeddedFonts() - this method returns fonts embedded in a presentation. void RemoveEmbeddedFont(IFontData fontData) - this method removes an embedded font from a presentation. The following sample demonstrates an use case for these new methods:

// load a presentation with embedded "FunSized" font
using (Presentation pres = new Presentation("pres.ppt"))
    // render a slide that contains a text frame that uses embedded "FunSized"
    pres.Slides[0].GetThumbnail(new Size(960, 720)).Save("pres-1.png", ImageFormat.Png);
	IFontsManager fontsManager = pres.FontsManager;
	// get all embedded fonts
    IFontData[] embeddedFonts = fontsManager.GetEmbeddedFonts();
	// find "FunSized" font
    IFontData funSizedEmbeddedFont = Array.Find(embeddedFonts, delegate(IFontData data)
        return data.FontName == "FunSized";

    // remove "FunSized" font

    // render the presentation; removed "FunSized" font is replaced to an existing one
    pres.Slides[0].GetThumbnail(new Size(960, 720)).Save("pres-2.png", ImageFormat.Png);

    // save the presentation without embedded "FunSized" font
    pres.Save("37537-2.ppt", SaveFormat.Ppt);

New responsive HTML controller has been added

The new class ResponsiveHtmlController has been added to provide the possibility to generate responsive HTML files.

This controller can be used in the same manner as other HTML controllers:

using (var pres = new Presentation("pres.pptx"))
  ResponsiveHtmlController controller = new ResponsiveHtmlController();
  HtmlOptions htmlOptions = new HtmlOptions
    HtmlFormatter = HtmlFormatter.CreateCustomFormatter(controller)    
  pres.Save("pres.html", SaveFormat.Html, htmlOptions);

Otp value has been added to LoadFormat and SaveFormat enumerations

The new Otp value has been added to Aspose.Slides.LoadFormat and Aspose.Slides.SaveFormat enumerations. This value represents the OpenOffice OTP Presentation template format.
