例子

VBA：

Sub Example_ShowRasterImage()
    ' This example returns the current setting of
    ' ShowRasterImage. It then changes the value, and finally
    ' it resets the value back to the original setting.
    
    Dim preferences As AcadPreferences
    Dim currShowRasterImage As Boolean
    
    Set preferences = ThisDrawing.Application.Preferences
    
    ' Retrieve the current ShowRasterImage value
    currShowRasterImage = preferences.DISPLAY.ShowRasterImage
    MsgBox "The current value for ShowRasterImage is " & preferences.DISPLAY.ShowRasterImage, vbInformation, "ShowRasterImage Example"
    
    ' Change the value for ShowRasterImage
    preferences.DISPLAY.ShowRasterImage = Not (currShowRasterImage)
    MsgBox "The new value for ShowRasterImage is " & preferences.DISPLAY.ShowRasterImage, vbInformation, "ShowRasterImage Example"
    
    ' Reset ShowRasterImage to its original value
    preferences.DISPLAY.ShowRasterImage = currShowRasterImage
    MsgBox "The ShowRasterImage value is reset to " & preferences.DISPLAY.ShowRasterImage, vbInformation, "ShowRasterImage Example"
End Sub
