命名空間： Microsoft.Ink
組件： Microsoft.Ink (在 Microsoft.Ink.dll 中)

語法

'宣告
Public Property Height As Single
'用途
Dim instance As DrawingAttributes

value = instance.Height

instance.Height = value

public float Height { get; set; }

public:

    float get ();
    void set (float value);

屬性值

型別：System.Single
繪製筆墨時，筆尖的 Y 軸維度或高度。

值	意義
1	筆尖高度是一個 (1) HIMETRIC 單位。
Single	表示筆尖高度的值，以 HIMETRIC 為單位。

備註

Height 屬性以 HIMETRIC 為單位。

這個屬性只適用於 Rectangle 筆尖，這是 PenTip 列舉值。值表示矩形側邊的高度。如果使用 Ball 筆尖值，則筆尖高度等於 Width 屬性，而且會忽略 Height 屬性。

精確度限於 HIMETRIC 單位的千分之一 (小數點後三位數)。例如，如果指定 2.0006 這個值，則最精確的度量為 2.001。

範例

using Microsoft.Ink;
//...
    private System.Windows.Forms.MenuItem menuInkHeightShort;
    private System.Windows.Forms.MenuItem menuInkHeightTall;
    private InkCollector theInkCollector;
    private System.Windows.Forms.MenuItem checkedHeight;

//...
    private void menuInkHeightShort_Click(
    object sender, System.EventArgs e)
    {
        checkedHeight.Checked = false;
        // Set the height to about one pixel in HIMETRIC
        theInkCollector.DefaultDrawingAttributes.Height = 30;
        checkedHeight = menuInkHeightShort;
        checkedHeight.Checked = true;
        Refresh();
    }

    private void menuInkHeightTall_Click(
    object sender, System.EventArgs e)
    {
        checkedHeight.Checked = false;
        // Set the height about ten pixels tall in HIMETRIC
        theInkCollector.DefaultDrawingAttributes.Height = 300;
        checkedHeight = menuInkHeightTall;
        checkedHeight.Checked = true;
        Refresh();
    }
