这样行不行：
Type RECT
left As Long
top As Long
right As Long
bottom As Long
End Type
Type RGNDATAHEADER
dwSize As Long
iType As Long
nCount As Long
nRgnSize As Long
rcBound As RECT
End Type
Type RGNDATA
rdh As RGNDATAHEADER
Buffer As String*1
End Type
Public Declare Function GetRegionData Lib "gdi32"( ByVal hRgn As Long, ByVal dwCount As Long,
lpRgnData As Any) As Long
Dim rd As RGNDATA
GetRegionData hr, Lenb(rd), rd
得到rd后，你可将它Copy到Byte数组内保存，就可以写到文件中。具体方法参见：
