object.Mask

对象

类型：层状态管理器

此属性适用的对象。

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：打印打开或关闭
• acLsPlotStyle：绘图风格

言论

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，要保存“颜色”和“线型”属性，请指定以下内容：

acLsColor + acLsLineType

例子

工 务 局：

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(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
