[Insight-users] double to float problem

[yasser salman]

Hello luis
thanks luis it works but i have 2 questions:
1- is there any modification that i'll do in my itk
code when converting to 2.4.1 ?
2- what Cmake suitable for my VC++ ver 6?
 ( i use 1.8.3 and when i try 2.2 the message error
occured requesting MFC7.dll !! may it needs VC.net or
somthing like that).
thanks luis.,
yasser
