请教如何用选择集取到光栅图像？

请教各位大侠以下的问题：


小弟最近用VBA编程时，需要穷举图纸中的所有光栅图像。这是小弟的源代码：


Dim        a         As AcadSelectionSet


Set        a = ThisDrawing.SelectionSets.Add("SSS67ETEXC")


               Dim ft(0 To 1) As Integer<BR>               Dim fd(0 To 1) As Variant<BR>               ft(0) = 0<BR>               fd(0) = "IMAGEDEF"<BR>                        ft(1) = 8<BR>               fd(1) = "*"


a.Select acSelectionSetAll, , , ft, fd


关键是选择集的过滤条件 Filter的问题。


这个组码是我将.dwg转换成dxf后查到的。可是用这个方式却怎么也取不到


光栅对象。


请问，如何用选择集取到所有的光栅对象呢？


谢谢各位！
