取得這個 Graphics 的垂直解析度。
public:
property float DpiY { float get(); };
public float DpiY { get; }
member this.DpiY : single
Public ReadOnly Property DpiY As Single
屬性值
這個 Graphics 所支援的垂直解析度的值,以 DPI 為單位。
範例
下列方法顯示 和 DpiY 屬性的使用DpiX方式。 此範例是設計來搭配 Windows Form 使用。 若要執行此範例,請將它貼到包含 ListBox 具名 listBox1 的表單中,並從表單的建構函式呼叫此方法。
private:
void PopulateListBoxWithGraphicsResolution()
{
Graphics^ boxGraphics = listBox1->CreateGraphics();
// Graphics* formGraphics = this->CreateGraphics();
listBox1->Items->Add( String::Format( "ListBox horizontal resolution: {0}", boxGraphics->DpiX ) );
listBox1->Items->Add( String::Format( "ListBox vertical resolution: {0}", boxGraphics->DpiY ) );
delete boxGraphics;
}
private void PopulateListBoxWithGraphicsResolution()
{
Graphics boxGraphics = listBox1.CreateGraphics();
Graphics formGraphics = this.CreateGraphics();
listBox1.Items.Add("ListBox horizontal resolution: "
+ boxGraphics.DpiX);
listBox1.Items.Add("ListBox vertical resolution: "
+ boxGraphics.DpiY);
boxGraphics.Dispose();
}
Private Sub PopulateListBoxWithGraphicsResolution()
Dim boxGraphics As Graphics = listBox1.CreateGraphics()
Dim formGraphics As Graphics = Me.CreateGraphics()
listBox1.Items.Add("ListBox horizontal resolution: " _
& boxGraphics.DpiX)
listBox1.Items.Add("ListBox vertical resolution: " _
& boxGraphics.DpiY)
boxGraphics.Dispose()
End Sub
