// Convert the first PowerPoint page to a PNG file.
page.ConvertToImage(ImageType.PNG, Program.RootPath + "Output.png");

C# Sample Code for PowerPoint to Bmp

Or use this piece of C# code to implement PowerPoint to Bmp conversion.

// Used to register all DLL assemblies.
WorkRegistry.Reset();

// Load a PowerPoint file.
String inputFilePath = Program.RootPath + "\\" + "1.pptx";
PPTXDocument doc = new PPTXDocument(inputFilePath);

// Get the first page of PowerPoint file.

// Used to register all DLL assemblies.
WorkRegistry.Reset();

// Load a PowerPoint file.
String inputFilePath = Program.RootPath + "\\" + "1.pptx";
PPTXDocument doc = new PPTXDocument(inputFilePath);

// Get the first page of PowerPoint.
PPTXPage page = (PPTXPage)doc.GetPage(0);

// Convert the first page to a REImage object.
REImage image = new REImage(page.ConvertToImage());

// Do something ...

C# Sample Code for PowerPoint to .NET Bitmap

Moreover, our SDK also allows you to render PowerPoint to .NET Bitmap in C# programming.

// Used to register all DLL assemblies.
WorkRegistry.Reset();

// Load a PowerPoint file.
String inputFilePath = Program.RootPath + "\\" + "1.pptx";
PPTXDocument doc = new PPTXDocument(inputFilePath);

// Get the first page of PowerPoint.
PPTXPage page = (PPTXPage)doc.GetPage(0);

// Render the page to a Bitmap with default setting.
Bitmap bitmap1 = page.GetBitmap();
bitmap1.Save(inputFilePath + "_1.bmp");
//  ...

// Enlarge the page with factor 2.
float zoomRatio = 2.0F;
Bitmap bitmap2 = page.GetBitmap(zoomRatio);
bitmap2.Save(inputFilePath + "_2.bmp");
//  ...

// Render the page with a resolution of 300 dpi.
int targetResolution = 300;
Bitmap bitmap3 = page.GetBitmap(targetResolution);
bitmap3.Save(inputFilePath + "_3.bmp");
//  ...
