例

VBA:

Sub Example_ShowRotation()
    ' This example adds a raster image in model space and rotates the image.
    ' One rotation is done without angle limits, one is done with ShowRotation,
    ' which limits rotations to 90 degrees
    
    ' This example uses the "downtown.jpg" found in the sample
    ' directory. If you do not have this image, or it is located
    ' in a different directory, insert a valid path and file name
    ' for the imageName variable below.
    
    Dim insertionPoint(0 To 2) As Double
    Dim scalefactor As Double, rotationAngle As Double
    Dim imageName As String
    Dim rasterObj As AcadRasterImage
    
    imageName = "c:\Autocad\sample\downtown.jpg"
    
    ' Define Raster object
    insertionPoint(0) = 5: insertionPoint(1) = 5: insertionPoint(2) = 0
    scalefactor = 1#: rotationAngle = 0
    
    On Error GoTo ERRORTRAP
    
    ' Loads a raster image into model space
    Set rasterObj = ThisDrawing.ModelSpace.AddRaster(imageName, insertionPoint, scalefactor, rotationAngle)
        
    ' Limit the raster image rotations to 90 degrees
    rasterObj.ShowRotation = True
    
    ' Rotate the raster image 180 degrees
    rasterObj.Rotate insertionPoint, 180
    ThisDrawing.Application.ZoomAll
    
    Exit Sub
    
    ' If you get an error (most likely a problem with the file path),
    ' then display an error message
ERRORTRAP:
    If Err.Description <> "" Then
        MsgBox Err.Description
    End If
End Sub
