## Examples



Shows how to adjust paper size, orientation, margins, along with other settings for a section. 
```cpp
auto doc = System::MakeObject<Aspose::Words::Document>();
auto builder = System::MakeObject<Aspose::Words::DocumentBuilder>(doc);

builder->get_PageSetup()->set_PaperSize(PaperSize::Legal);
builder->get_PageSetup()->set_Orientation(Orientation::Landscape);
builder->get_PageSetup()->set_TopMargin(ConvertUtil::InchToPoint(1.0));
builder->get_PageSetup()->set_BottomMargin(ConvertUtil::InchToPoint(1.0));
builder->get_PageSetup()->set_LeftMargin(ConvertUtil::InchToPoint(1.5));
builder->get_PageSetup()->set_RightMargin(ConvertUtil::InchToPoint(1.5));
builder->get_PageSetup()->set_HeaderDistance(ConvertUtil::InchToPoint(0.2));
builder->get_PageSetup()->set_FooterDistance(ConvertUtil::InchToPoint(0.2));

builder->Writeln(u"Hello world!");

doc->Save(get_ArtifactsDir() + u"PageSetup.PageMargins.docx");
```


Shows how to specify page properties in inches. 
```cpp
auto doc = System::MakeObject<Aspose::Words::Document>();
auto builder = System::MakeObject<Aspose::Words::DocumentBuilder>(doc);

// A section's "Page Setup" defines the size of the page margins in points.
// We can also use the "ConvertUtil" class to use a more familiar measurement unit,
// such as inches when defining boundaries.
System::SharedPtr<Aspose::Words::PageSetup> pageSetup = builder->get_PageSetup();
pageSetup->set_TopMargin(ConvertUtil::InchToPoint(1.0));
pageSetup->set_BottomMargin(ConvertUtil::InchToPoint(2.0));
pageSetup->set_LeftMargin(ConvertUtil::InchToPoint(2.5));
pageSetup->set_RightMargin(ConvertUtil::InchToPoint(1.5));

// An inch is 72 points.
ASPOSE_ASSERT_EQ(72.0, ConvertUtil::InchToPoint(1));
ASPOSE_ASSERT_EQ(1.0, ConvertUtil::PointToInch(72));

// Add content to demonstrate the new margins.
builder->Writeln(System::String::Format(u"This Text is {0} points/{1} inches from the left, ", pageSetup->get_LeftMargin(), ConvertUtil::PointToInch(pageSetup->get_LeftMargin())) + System::String::Format(u"{0} points/{1} inches from the right, ", pageSetup->get_RightMargin(), ConvertUtil::PointToInch(pageSetup->get_RightMargin())) + System::String::Format(u"{0} points/{1} inches from the top, ", pageSetup->get_TopMargin(), ConvertUtil::PointToInch(pageSetup->get_TopMargin())) + System::String::Format(u"and {0} points/{1} inches from the bottom of the page.", pageSetup->get_BottomMargin(), ConvertUtil::PointToInch(pageSetup->get_BottomMargin())));

doc->Save(get_ArtifactsDir() + u"UtilityClasses.PointsAndInches.docx");
```
