获取累积偏移量和剪辑区域。

public:
 void GetContextInfo([Runtime::InteropServices::Out] System::Drawing::PointF % offset, [Runtime::InteropServices::Out] System::Drawing::Region ^ % clip);
[System.Runtime.Versioning.SupportedOSPlatform("windows")]
public void GetContextInfo (out System.Drawing.PointF offset, out System.Drawing.Region? clip);
[<System.Runtime.Versioning.SupportedOSPlatform("windows")>]
member this.GetContextInfo : PointF * Region -> unit
Public Sub GetContextInfo (ByRef offset As PointF, ByRef clip As Region)

参数

offset
PointF

此方法返回时,包含累积偏移量。 此参数被视为未初始化。

clip
Region

此方法返回时,包含累积剪辑区域;如果剪辑区域是无限的,则包含 null。 此参数被视为未初始化。
