提供一組靜態 InkDrawingAttributes 屬性，以轉譯 InkCanvas上的鉛筆筆劃。

呼叫 InkDrawingAttributes.CreateForPencil 並存取 InkDrawingAttributes.PencilProperties，以取得此類別的實例。

範例

此範例示範如何使用鉛筆屬性來轉譯筆墨筆劃。

首先，我們會在 XAML 中宣告 InkCanvas 。

在程式碼後置中，我們會定義函 SetPencilInkStyle() 式來指定鉛筆筆劃屬性。

<InkCanvas x:Name="inkCanvas"/>

public sealed partial class Sample : Page
{
  public SetPencilInkStyle()
  {
    // Initialize the pencil stroke attributes.
    InkDrawingAttributes pencilAttributes = InkDrawingAttributes.CreateForPencil();
    pencilAttributes.Color = Windows.UI.Colors.Red;
    pencilAttributes.Size = new Windows.Foundation.Size(3, 3);
    Debug.Assert(attributes.Kind == InkDrawingAttributesKind.Pencil);
    pencilAttributes.PencilProperties.Opacity = 0.5f;
    // Update InkPresenter with the pencil attributes.
    inkCanvas.InkPresenter.UpdateDefaultDrawingAttributes(pencilAttributes);
  }
}

struct MainPage : MainPageT<MainPage>
{
    void SetPencilInkStyle()
    {
        // Initialize the pencil stroke attributes.
        auto pencilAttributes{ Windows::UI::Input::Inking::InkDrawingAttributes::CreateForPencil() };
        pencilAttributes.Color(Windows::UI::Colors::Red());
        pencilAttributes.Size({ 3, 3 });
        WINRT_ASSERT(pencilAttributes.Kind() == Windows::UI::Input::Inking::InkDrawingAttributesKind::Pencil);
        pencilAttributes.PencilProperties().Opacity(.5f);
        // Update the InkPresenter with the pencil attributes.
        m_inkCanvas.InkPresenter().UpdateDefaultDrawingAttributes(pencilAttributes);
    }
}

public sealed partial class Sample : Page
{
  public SetPencilInkStyle()
  {
    // Initialize the pencil stroke attributes.
    InkDrawingAttributes^ pencilAttributes = InkDrawingAttributes::CreateForPencil();
    pencilAttributes->Color = Windows::UI::Colors::Red;
    pencilAttributes->Size = Windows::Foundation::Size(3, 3);
    assert(pencilAttributes->Kind == InkDrawingAttributesKind::Pencil);
    pencilAttributes->PencilProperties->Opacity = 0.5f;
    // Update the InkPresenter with the pencil attributes.
    inkCanvas->InkPresenter->UpdateDefaultDrawingAttributes(pencilAttributes);
  }
}

備註

根據預設，鉛筆會繪製柔邊、紋理和半透明筆劃， (適用于使用圓形畫筆提示) 分層網底效果。 筆觸色彩 (濃度) 是根據偵測到的手寫筆壓力。

屬性

Opacity

取得或設定用於在 InkCanvas上呈現鉛筆筆劃的透明度層級。

不透明度是 InkDrawingAttributes的靜態屬性。

呼叫 InkDrawingAttributes.CreateForPencil 並存取 InkDrawingAttributes.PencilProperties，以取得此類別的實例。
