using namespace std;
using namespace Spire::Presentation;

int main()
{
	std::wstring inputFile = DataPath"Encrypt.pptx";
	std::wstring outputFile = OutputPath"Encrypt.pptx";

	//Create a PPT document
	Presentation* presentation = new Presentation();

	//Load the document from disk
	presentation->LoadFromFile(inputFile.c_str());

	//Get the password that the user entered
	std::wstring password = L"e-iceblue";

	//Encrypy the document with the password
	presentation->Encrypt(password.c_str());

	//Save the document
	presentation->SaveToFile(outputFile.c_str(), FileFormat::Pptx2010);
	delete presentation;

}
```

### Convert PowerPoint to PDF in C++

```c++
#include "pch.h"

using namespace std;
using namespace Spire::Presentation;

int main()
{
	std::wstring inputFile = DataPath"ToPDF.pptx";
	std::wstring outputFile = OutputPath"ToPDF.pdf";

	//Create a PPT document
	Presentation* ppt = new Presentation();
	//Load the file from disk.
	ppt->LoadFromFile(inputFile.c_str());

	//Save the document to PDF format
	ppt->SaveToFile(outputFile.c_str(), FileFormat::PDF);

	delete ppt;
}
```

### Convert PowerPoint to Images in C++

```c++
#include "pch.h"

using namespace std;
using namespace Spire::Presentation;

int main()
{
	std::wstring inputFile = DataPath"ToImage.pptx";
	std::wstring outputFile = OutputPath"Image/ToImage/";

	//Create a PPT document
	Presentation* ppt = new Presentation();
	//Load the file from disk.
	ppt->LoadFromFile(inputFile.c_str());

	//Save PPT document to images
	SlideCollection* slides = ppt->GetSlides();
	for (int i = 0; i < slides->GetCount(); i++)
	{
		ISlide* slide = slides->GetItem(i);
		Stream* image = slide->SaveAsImage();
		image->Save((outputFile + L"ToImage_img_" + to_wstring(i) + L".png").c_str());
	}

	delete ppt;
}
```

### Convert PowerPoint to SVG in C++

```c++
#include "pch.h"

using namespace std;
using namespace Spire::Presentation;

int main()
{
	std::wstring inputFile = DataPath"ToSVG.pptx";
	std::wstring outputFile = OutputPath"SVG/ToSVG/";

	//Create a PPT document
	Presentation* ppt = new Presentation();
	//Load the file from disk.
	ppt->LoadFromFile(inputFile.c_str());

	//Retain the notes while converting PowerPoint file to svg file.
	ppt->SetIsNoteRetained(true);
	SlideCollection* slides = ppt->GetSlides();
	for (int i = 0; i < slides->GetCount(); i++)
	{
		Stream* svg = slides->GetItem(i)->SaveToSVG();
		svg->Save((outputFile + L"ToSVG-" + to_wstring(i) + L".svg").c_str());
		svg->Dispose();
	}
	delete ppt;

}
