管理SmartArt形状

创建SmartArt形状

Aspose.Slides for C++ 现在支持从头开始在幻灯片中添加自定义SmartArt形状。Aspose.Slides for C++提供了最简单的API,以最简便的方式创建SmartArt形状。要在幻灯片中创建SmartArt形状,请按照以下步骤进行操作:

  • 创建一个 Presentation 类的实例。
  • 通过使用其索引获取幻灯片的引用。
  • 通过设置布局类型添加SmartArt形状。
  • 将修改后的演示文稿写入PPTX文件。
For complete examples and data files, please go to https://github.com/aspose-slides/Aspose.Slides-for-C
// The path to the documents directory.
const String outPath = u"../out/SimpleSmartArt_out.pptx";
// Load the desired the presentation
SharedPtr<Presentation> pres = MakeObject<Presentation>();
// Add SmartArt BasicProcess
System::SharedPtr<Aspose::Slides::SmartArt::ISmartArt> smart = pres->get_Slides()->idx_get(0)->get_Shapes()->AddSmartArt(10, 10, 400, 300, SmartArtLayoutType::BasicBlockList);
// Save Presentation
pres->Save(outPath, Aspose::Slides::Export::SaveFormat::Pptx);

在幻灯片中访问SmartArt形状

以下代码将用于访问演示文稿幻灯片中添加的SmartArt形状。在示例代码中,我们将遍历幻灯片中的每个形状,并检查它是否为SmartArt形状。如果形状是SmartArt类型,则将其强制转换为SmartArt实例。

For complete examples and data files, please go to https://github.com/aspose-slides/Aspose.Slides-for-C
// The path to the documents directory.
const String templatePath = u"../templates/SmartArt.pptx";
// Load the desired the presentation
SharedPtr<Presentation> pres = MakeObject<Presentation>(templatePath);
// Traverse through every shape inside first slide
for (int x = 0; x < pres->get_Slides()->idx_get(0)->get_Shapes()->get_Count(); x++)
{
SharedPtr<IShape> shape = pres->get_Slides()->idx_get(0)->get_Shapes()->idx_get(x);
if (System::ObjectExt::Is<Aspose::Slides::SmartArt::SmartArt>(shape))
{
System::SharedPtr<Aspose::Slides::SmartArt::SmartArt> smart = System::DynamicCast_noexcept<Aspose::Slides::SmartArt::SmartArt>(shape);
System::Console::WriteLine(u"Smart Art Name = " + smart->get_Name());
}
}

访问具有特定布局类型的SmartArt形状

以下示例代码将帮助访问具有特定布局类型的SmartArt形状。请注意,您不能更改SmartArt的布局类型,因为它是只读的,并且仅在添加SmartArt形状时设置。

  • 创建一个 Presentation 类的实例,并加载具有SmartArt形状的演示文稿。
  • 通过使用其索引获取第一个幻灯片的引用。
  • 遍历第一个幻灯片中的每个形状。
  • 检查形状是否为SmartArt类型,并在它是SmartArt时将所选形状强制转换为SmartArt。
  • 检查具有特定布局类型的SmartArt形状,并执行所需的操作。
For complete examples and data files, please go to https://github.com/aspose-slides/Aspose.Slides-for-C
// The path to the documents directory.
const String templatePath = u"../templates/SmartArt.pptx";
// Load the desired the presentation
SharedPtr<Presentation> pres = MakeObject<Presentation>(templatePath);
// Traverse through every shape inside first slide
for (int x = 0; x < pres->get_Slides()->idx_get(0)->get_Shapes()->get_Count(); x++)
{
SharedPtr<IShape> shape = pres->get_Slides()->idx_get(0)->get_Shapes()->idx_get(x);
if (System::ObjectExt::Is<Aspose::Slides::SmartArt::SmartArt>(shape))
{
System::SharedPtr<Aspose::Slides::SmartArt::SmartArt> smart = System::DynamicCast_noexcept<Aspose::Slides::SmartArt::SmartArt>(shape);
System::Console::WriteLine(u"Smart Art Name = " + smart->get_Name());
// Checking SmartArt Layout
if (smart->get_Layout() == SmartArtLayoutType::BasicBlockList)
{
System::Console::WriteLine(u"Do some thing here....");
}
}
}

更改SmartArt形状样式

以下示例代码将帮助访问具有特定布局类型的SmartArt形状。

  • 创建一个 Presentation 类的实例,并加载具有SmartArt形状的演示文稿。
  • 通过使用其索引获取第一个幻灯片的引用。
  • 遍历第一个幻灯片中的每个形状。
  • 检查形状是否为SmartArt类型,并在它是SmartArt时将所选形状强制转换为SmartArt。
  • 查找具有特定样式的SmartArt形状。
  • 为SmartArt形状设置新样式。
  • 保存演示文稿。
For complete examples and data files, please go to https://github.com/aspose-slides/Aspose.Slides-for-C
// The path to the documents directory.
const String templatePath = u"../templates/SmartArt.pptx";
const String outPath = u"../out/ChangeSmartArtStyle_out.pptx";
// Load the desired the presentation
SharedPtr<Presentation> pres = MakeObject<Presentation>(templatePath);
// Traverse through every shape inside first slide
for (int x = 0; x < pres->get_Slides()->idx_get(0)->get_Shapes()->get_Count(); x++)
{
SharedPtr<IShape> shape = pres->get_Slides()->idx_get(0)->get_Shapes()->idx_get(x);
if (System::ObjectExt::Is<Aspose::Slides::SmartArt::SmartArt>(shape))
{
System::SharedPtr<Aspose::Slides::SmartArt::SmartArt> smart = System::DynamicCast_noexcept<Aspose::Slides::SmartArt::SmartArt>(shape);
// Checking SmartArt style
if (smart->get_QuickStyle() == SmartArtQuickStyleType::SimpleFill)
{
// Changing SmartArt Style
smart->set_QuickStyle(SmartArtQuickStyleType::Cartoon);
}
}
}
// Save Presentation
pres->Save(outPath, Aspose::Slides::Export::SaveFormat::Pptx);

更改SmartArt形状颜色样式

在此示例中,我们将学习如何更改任何SmartArt形状的颜色样式。在以下示例代码中,将访问具有特定颜色样式的SmartArt形状并更改其样式。

  • 创建一个 Presentation 类的实例,并加载具有SmartArt形状的演示文稿。
  • 通过使用其索引获取第一个幻灯片的引用。
  • 遍历第一个幻灯片中的每个形状。
  • 检查形状是否为SmartArt类型,并在它是SmartArt时将所选形状强制转换为SmartArt。
  • 查找具有特定颜色样式的SmartArt形状。
  • 为SmartArt形状设置新颜色样式。
  • 保存演示文稿。
For complete examples and data files, please go to https://github.com/aspose-slides/Aspose.Slides-for-C
// The path to the documents directory.
const String templatePath = u"../templates/SmartArt.pptx";
const String outPath = u"../out/ChangeSmartArtShapeColorStyle.pptx";
// Load the desired the presentation
SharedPtr<Presentation> pres = MakeObject<Presentation>(templatePath);
// Traverse through every shape inside first slide
for (int x = 0; x < pres->get_Slides()->idx_get(0)->get_Shapes()->get_Count(); x++)
{
SharedPtr<IShape> shape = pres->get_Slides()->idx_get(0)->get_Shapes()->idx_get(x);
if (System::ObjectExt::Is<Aspose::Slides::SmartArt::SmartArt>(shape))
{
System::SharedPtr<Aspose::Slides::SmartArt::SmartArt> smart = System::DynamicCast_noexcept<Aspose::Slides::SmartArt::SmartArt>(shape);
if (smart->get_ColorStyle() == SmartArtColorType::ColoredFillAccent1)
{
// Changing SmartArt color type
smart->set_ColorStyle(SmartArtColorType::ColorfulAccentColors);
}
}
}
// Save Presentation
pres->Save(outPath, Aspose::Slides::Export::SaveFormat::Pptx);
