Format Text

Both the VSTO and Aspose.Slides methods take the following steps:

  • Open the source presentation.
  • Access the first slide.
  • Access the third text box.
  • Change the formatting of the text in the third text box.
  • Save the presentation to disk.

VSTO


 //Open the presentation

Presentation pres = new Presentation("source.ppt");

//Add Verdana font

FontEntity font = pres.Fonts[0];

FontEntity verdanaFont = new FontEntity(pres, font);

verdanaFont.FontName = "Verdana";

int verdanaFontIndex = pres.Fonts.Add(verdanaFont);

//Access the first slide

Slide slide = pres.GetSlideByPosition(1);

//Access the third shape

Shape shp = slide.Shapes[2];

//Change its text's font to Verdana and height to 32

TextFrame tf = shp.TextFrame;

Paragraph para = tf.Paragraphs[0];

Portion port = para.Portions[0];

port.FontIndex = verdanaFontIndex;

port.FontHeight = 32;

//Bolden it

port.FontBold = true;

//Italicize it

port.FontItalic = true;

//Change text color

port.FontColor = Color.FromArgb(0x33, 0x33, 0xCC);

//Change shape background color

shp.FillFormat.Type = FillType.Solid;

shp.FillFormat.ForeColor = Color.FromArgb(0xCC, 0xCC, 0xFF);

//Write the output to disk

pres.Write("outAspose.ppt");

Aspose.Slides


 PowerPoint.Presentation pres = null;

//Open the presentation

pres = Globals.ThisAddIn.Application.Presentations.Open("source.ppt",

	Microsoft.Office.Core.MsoTriState.msoFalse,

	Microsoft.Office.Core.MsoTriState.msoFalse,

	Microsoft.Office.Core.MsoTriState.msoTrue);

//Access the first slide

PowerPoint.Slide slide = pres.Slides[1];

//Access the third shape

PowerPoint.Shape shp = slide.Shapes[3];

//Change its text's font to Verdana and height to 32

PowerPoint.TextRange txtRange = shp.TextFrame.TextRange;

txtRange.Font.Name = "Verdana";

txtRange.Font.Size = 32;

//Bolden it

txtRange.Font.Bold = Microsoft.Office.Core.MsoTriState.msoCTrue;

//Italicize it

txtRange.Font.Italic = Microsoft.Office.Core.MsoTriState.msoCTrue;

//Change text color

txtRange.Font.Color.RGB = 0x00CC3333;

//Change shape background color

shp.Fill.ForeColor.RGB = 0x00FFCCCC;

//Reposition it horizontally

shp.Left -= 70;

//Write the output to disk

pres.SaveAs("outVSTO.ppt",

	PowerPoint.PpSaveAsFileType.ppSaveAsPresentation,

	Microsoft.Office.Core.MsoTriState.msoFalse);
