You can use TextFrame to add text and set its formatting, fonts etc.

 

Below is the C# code to do so, please also see the output presentation attached. It also gives you idea, how to use Aspose.Slides to change formatting of text.

 

C# Code

Presentation pres = new Presentation();

Slide sld = pres.GetSlideByPosition(1);

 

//Adding Title with textframe

Aspose.Slides.Rectangle rect = sld.Shapes.AddRectangle(432, 384, 4896, 720);

rect.LineFormat.ShowLines = false;

TextFrame tf = rect.AddTextFrame("Your Title Text");

 

//Center align it

tf.Paragraphs[0].Alignment = TextAlignment.Center;

 

//Set formatting

Portion port=tf.Paragraphs[0].Portions[0];

 

//To set font height

port.FontHeight = 44;

 

//To set font

FontEntity newFont=new FontEntity(pres, pres.Fonts[0]);

newFont.FontName = "Comic Sans MS";

int newFontIdx=pres.Fonts.Add(newFont);

port.FontIndex = newFontIdx; 

 

//To set color

port.FontColor = Color.BlueViolet; 

 

pres.Write("c:\\outTitle.ppt");

Here is the same code as above in JAVA.

JAVA

-------------------------------------------------------------------------------------------------------------

Presentation pres = new Presentation();

Slide sld = pres.getSlideByPosition(1);

//Adding Title with textframe

com.aspose.slides.Rectangle rect = sld.getShapes().addRectangle(432, 384, 4896, 720);

rect.getLineFormat().setShowLines(false);

TextFrame tf = rect.addTextFrame("Your Title Text");

//Center align it

tf.getParagraphs().get(0).setAlignment(TextAlignment.CENTER);

//Set formatting

Portion port = tf.getParagraphs().get(0).getPortions().get(0);

//To set font height

port.setFontHeight((short)44);

//To set font

FontEntity newFont = new FontEntity(pres, pres.getFonts().get(0));

newFont.setFontName("Comic Sans MS");

int newFontIdx = pres.getFonts().add(newFont);

port.setFontIndex(newFontIdx);

//To set color

port.setFontColor(Color.BLUE);

pres.write(new FileOutputStream("c:\\outTitle.ppt"));

O, I'm actually using VB .Net, but c# reads close enough so the example works for me :)
