设置倾斜角度（.NET）

倾斜角度决定了文本的向前或向后倾斜。角度表示与其垂直轴（90 度）的偏移。若要设置倾斜角度，请使用该属性更改文本样式或文本对象的属性。倾斜角必须以弧度为单位提供。正角表示向右倾斜，负值将添加到其上以将其转换为正等价物。ObliquingAngleOblique2*PI

创建倾斜文本

本示例创建一个单行文本对象，然后将其倾斜 45 度。

VB.NET

Imports Autodesk.AutoCAD.Runtime
Imports Autodesk.AutoCAD.ApplicationServices
Imports Autodesk.AutoCAD.DatabaseServices
Imports Autodesk.AutoCAD.Geometry
 
<CommandMethod("ObliqueText")> _
Public Sub ObliqueText()
    '' Get the current document and database
    Dim acDoc As Document = Application.DocumentManager.MdiActiveDocument
    Dim acCurDb As Database = acDoc.Database

    '' Start a transaction
    Using acTrans As Transaction = acCurDb.TransactionManager.StartTransaction()

        '' Open the Block table for read
        Dim acBlkTbl As BlockTable
        acBlkTbl = acTrans.GetObject(acCurDb.BlockTableId, _
                                     OpenMode.ForRead)

        '' Open the Block table record Model space for write
        Dim acBlkTblRec As BlockTableRecord
        acBlkTblRec = acTrans.GetObject(acBlkTbl(BlockTableRecord.ModelSpace), _
                                        OpenMode.ForWrite)

        '' Create a single-line text object
        Using acText As DBText = New DBText()
            acText.Position = New Point3d(3, 3, 0)
            acText.Height = 0.5
            acText.TextString = "Hello, World."

            '' Change the oblique angle of the text object to 45 degrees(0.707 in radians)
            acText.Oblique = 0.707

            acBlkTblRec.AppendEntity(acText)
            acTrans.AddNewlyCreatedDBObject(acText, True)
        End Using

        '' Save the changes and dispose of the transaction
        acTrans.Commit()
    End Using
End Sub
