Public API Changes

Method FontsLoader.GetFontFolders has been added

Returns folders where font files are searched. Those are folders that have been added with LoadExternalFonts method as well as system font folders.

string[] fontFolders = FontsLoader.GetFontFolders();

Method IChartData.SwitchRowColumn() has been added

Swap the data over the axis. Data being charted on the X axis will move to the Y axis and vice versa.

using (Presentation pres = new Presentation())
  IChart chart = pres.Slides[0].Shapes.AddChart(ChartType.ClusteredColumn, 100, 100, 400, 300);

  pres.Save(outputFileName, SaveFormat.PPTX);

New EmbedFontCharacters enum and AddEmbeddedFont methods has been added

To allow embedding fonts into Presentation the new EmbedFontCharacters enum and two overloads of AddEmbeddedFont method have been added:

EmbedFontCharacters enum has two members:

  • OnlyUsed: Embed only the characters used in the presentation (best for reducing file size).
  • All: Embed all characters (best for editing by other people).

New method AddEmbeddedFont with two overloads has been added to IFontsManager interface and FontsManager implementation class:

To embed font from existed IFontData:

  • void AddEmbeddedFont(IFontData fontData, EmbedFontCharacters embedFontRule)

To embed font from a binary data:

  • void AddEmbeddedFont(byte[] fontData, EmbedFontCharacters embedFontRule)

Using these methods and choosing the desired embedding rule (represented by EmbedFontCharacters enum), all fonts used in Presentation can be embedded:

IFontData[] allFonts = pres.FontsManager.GetFonts();
IFontData[] embeddedFonts = pres.FontsManager.GetEmbeddedFonts();
foreach (IFontData font in allFonts)
  if (!embeddedFonts.Contains(font))
    pres.FontsManager.AddEmbeddedFont(font, EmbedFontCharacters.All);

Or, using the new features of .NET framework, this snippet can be replaced with the following:

IFontData[] allFonts = pres.FontsManager.GetFonts();
IFontData[] embeddedFonts = pres.FontsManager.GetEmbeddedFonts();
foreach (IFontData font in allFonts.Except(embeddedFonts))
  pres.FontsManager.AddEmbeddedFont(font, EmbedFontCharacters.All);

Please note that an ArgumentException will be thrown if embedded font which is already embedded will be added again using AddEmbeddedFont method.

NotesStyle property has been added to IMasterNotesSlide interface and MasterNotesSlide class

NotesStyle property has been added to IMasterNotesSlide interface and MasterNotesSlide class respectively.

This property specifies the style of a notes text.

using (Presentation presentation = new Presentation(path + "Presentation.pptx"))
  IMasterNotesSlide notesMaster = presentation.MasterNotesSlideManager.MasterNotesSlide;
  if (notesMaster != null)
    // Get MasterNotesSlide text style
    ITextStyle notesStyle = notesMaster.NotesStyle;
	//Set symbol bullet for the first level paragraphs
	IParagraphFormat paragraphFormat = notesStyle.GetLevel(0);
	paragraphFormat.Bullet.Type = BulletType.Symbol;
  presentation.Save(path + "Presentation-out.pptx", SaveFormat.Pptx);

StretchOffsetLeft, StretchOffsetTop, StretchOffsetRight and StretchOffsetBottom properties have been added to IPictureFillFormat interface and PictureFillFormat class

Properties StretchOffsetLeft, StretchOffsetTop, StretchOffsetRight and StretchOffsetBottom has been added to IPictureFillFormat interface and PictureFillFormat class respectively.

These properties specify a fill rectangle. When stretching of an image is specified, a source rectangle is scaled to fit the specified fill rectangle.

Each edge of the fill rectangle is defined by a percentage offset from the corresponding edge of the shape’s bounding box. A positive percentage specifies an inset, while a negative percentage specifies an outset.

For example, a left offset of 25% specifies that the left edge of the fill rectangle is located to the right of the bounding box’s left edge by an amount equal to 25% of the bounding box’s width.

Code example:

using (Presentation presentation = new Presentation())
  // Get the first slide of presentation
  ISlide slide = presentation.Slides[0];

  // Add an AutoShape of Rectangle type
  IAutoShape aShape = slide.Shapes.AddAutoShape(ShapeType.Rectangle, 100, 100, 300, 300);
  // Create image
  Bitmap img = new Bitmap("image.png");
  IPPImage imgEx = presentation.Images.AddImage(img);
  // Set shape's fill type
  aShape.FillFormat.FillType = FillType.Picture;
  // Set shape's picture fill mode
  aShape.FillFormat.PictureFillFormat.PictureFillMode = PictureFillMode.Stretch;
  // Set image to fill the shape
  aShape.FillFormat.PictureFillFormat.Picture.Image = imgEx;
  // Specify image offsets from the corresponding edge of the shape's bounding box
  aShape.FillFormat.PictureFillFormat.StretchOffsetLeft = 25;
  aShape.FillFormat.PictureFillFormat.StretchOffsetRight = 25;
  aShape.FillFormat.PictureFillFormat.StretchOffsetTop = -20;
  aShape.FillFormat.PictureFillFormat.StretchOffsetBottom = -10;

  // Save created presentation
  presentation.Save("StretchOffsetExample.pptx", SaveFormat.Pptx);
