TabletPropertyMetrics.Maximum 字段

项目
10/28/2008

指定 Tablet 为此属性报告的最大值（采用逻辑单位）。

命名空间： Microsoft.Ink
程序集： Microsoft.Ink（在 Microsoft.Ink.dll 中）

语法

声明
Public Maximum As Integer
用法
Dim instance As TabletPropertyMetrics
Dim value As Integer

value = instance.Maximum

instance.Maximum = value

public int Maximum

public:
int Maximum

public int Maximum

public var Maximum : int

字段值

类型：System.Int32
Tablet 为此属性报告的最大值。

备注

例如，报告介于 0 和 9000 之间的 x 值的 Tablet 具有逻辑最大值 9000。

示例

在此示例中，修改 InkOverlay 对象的所有选定 Stroke 对象，以便该笔画的后半部分的每个点包含允许的最大 NormalPressure 数据包值。

使用 GetPacketValuesByProperty 方法获取 Stroke 对象的后半部分的 NormalPressure 数据包值。然后，使用 SetPacketValuesByProperty 方法将这些值设置为最大允许值（通过 GetPacketDescriptionPropertyMetrics 方法获取），并将这些值重新应用于该笔画。

Try
    For Each S As Stroke In mInkOverlay.Selection
        ' get the PacketProperty.NormalPressure metrics for the stroke
        Dim metrics As TabletPropertyMetrics = S.GetPacketDescriptionPropertyMetrics(PacketProperty.NormalPressure)
        ' get the starting point
        Dim startPt As Integer = S.PacketCount / 2
        ' get the NormalPressure values starting at startPt
        Dim npValues() As Integer = S.GetPacketValuesByProperty(PacketProperty.NormalPressure, startPt)
        ' set the NormalPressure values to max
        For k As Integer = 0 To npValues.Length - 1
            npValues(k) = metrics.Maximum
        Next
        ' set the NormalPressure values starting at startPt
        S.SetPacketValuesByProperty(PacketProperty.NormalPressure, startPt, npValues)
    Next

Catch ex As ArgumentException
    ' This exception will be raised if PacketProperty.NormalPressure is not supported
    ' This will be the case if creating strokes with a mouse
End Try

try
{
    foreach (Stroke S in mInkOverlay.Selection)
    {
        // get the PacketProperty.NormalPressure metrics for the stroke
        TabletPropertyMetrics metrics = S.GetPacketDescriptionPropertyMetrics(PacketProperty.NormalPressure);
        // get the starting point
        int startPt = S.PacketCount / 2;
        // get the NormalPressure values starting at startPt
        int[] npValues = S.GetPacketValuesByProperty(PacketProperty.NormalPressure, startPt);
        // set the NormalPressure values to max
        for (int k = 0; k < npValues.Length; k++)
        {
            npValues[k] = metrics.Maximum;
        }
        // set the NormalPressure values starting at startPt
        S.SetPacketValuesByProperty(PacketProperty.NormalPressure, startPt, npValues);
    }
}
catch (ArgumentException)
{
    // This exception will be raised if PacketProperty.NormalPressure is not supported
    // This will be the case if creating strokes with a mouse
