指定 MText 对象的相对行距系数。

支持的平台：仅限 Windows

签名

VBA：

object.LineSpacingFactor

对象

类型：GeoPositionMarker、MText

此属性应用于的对象。

属性值

只读：不

类型：双

对象的相对行距系数。输入一个介于 0.25 和 4（含 0.25 和 4）之间的值。MText

言论

间距系数是一行文本的基线与下一行文本行的基线之间的垂直距离。间距系数设置为单行间距的倍数。

可以使用该属性将行距设置为“至少”指定距离或“完全”指定距离。LineSpacingStyle

例子

VBA：

Sub Example_LineSpacingFactor()
    ' This example creates an MText object in model space
    ' and then finds the LineSpacingFactor for the object.
    
    Dim MTextObj As AcadMText
    Dim corner(0 To 2) As Double
    Dim width As Double
    Dim text As String
    corner(0) = 0#: corner(1) = 10#: corner(2) = 0#
    width = 10
    text = "This is the text String for the mtext Object"

    ' Creates the MText Object
    Set MTextObj = ThisDrawing.ModelSpace.AddMText(corner, width, text)
    ZoomAll
    
    ' Find the current LineSpacingFactor
    Dim currFactor As Double
    currFactor = MTextObj.LineSpacingFactor
    MsgBox "The LineSpacingFactor for the MText object is: " & currFactor
    
    ' Change the LineSpacingFactor
    MTextObj.LineSpacingFactor = 4
    MsgBox "The LineSpacingFactor for the MText object is: " & MTextObj.LineSpacingFactor
    
    ' Reset the LineSpacingFactor
    MTextObj.LineSpacingFactor = currFactor
    MsgBox "The LineSpacingFactor for the MText object is: " & MTextObj.LineSpacingFactor
    
End Sub
