Mask 属性（ActiveX）

指定要恢复的图层属性。

支持的平台：仅限 Windows

签名

VBA：

object.Mask

对象

类型：LayerStateManager

此属性应用于的对象。

属性值

只读：不

类型：枚举AcLayerStateMask

表示要恢复的图层属性的数字。使用下表中的常量来标识图层属性：

acLsAll：所有图层属性
acLsColor：颜色
acLsFrozen：冷冻或解冻
acLsLineType：线型
acLsLineWeight：线宽
acLsLocked：锁定或解锁
acLsNewViewport：冻结或解冻的新视口图层
acLsNone：没有
acLsOn：开或关
acLsPlot：开或关绘图
acLsPlotStyle：剧情风格

言论

LayerStateManager 方法使用 Mask 属性来标识要还原的图层属性。首先，在使用 LayerStateManager 方法保存图层设置时设置该属性。但是，Save 方法实际上保存了每个绘图图层的所有属性。您可以在恢复图层设置之前随时更新属性，从而更改要恢复的图层属性。RestoreMaskSaveMask

要在蒙版中指定多个图层属性，请添加表示这些属性的常量。例如，若要保存 Color 和 LineType 属性，请指定以下内容：

acLsColor + acLsLineType

例子

VBA：

Sub Example_SetMask()
    ' The following code updates the Mask property of layer
    ' settings saved under the name "ColorLineType, so that
    ' Color, LineType, and LineWeight layer properties will
    ' be restored by a Restore operation.
    
    Dim oLSM As AcadLayerStateManager
    Dim settings As AcLayerStateMask
    
    Set oLSM = ThisDrawing.Application. _
       GetInterfaceObject("AutoCAD.AcadLayerStateManager." & Left(CStr(AcadApplication.Version), 2))
    oLSM.SetDatabase ThisDrawing.Database
    
    oLSM.Save "ColorLinetype", acLsColor + acLsLineType
    
    ' Retrieve the current mask setting from ColorLinetype
    settings = oLSM.Mask("ColorLinetype")
       
    ' Set mask so that Color, LineType, and LineWeight
    ' properties will be restored by a Restore operation
    settings = acLsColor + acLsLineType + acLsLineWeight
         
    ' Commit the new settings mask to ColorLinetype
    oLSM.Mask("ColorLinetype") = settings

End Sub
