[Insight-users] Loss of bit depth in converting fron png to bmp

[rg32@njit.edu]

Hi all ,
I'm working on a program which has to process a png image and return a bmp 
image.For doing the conversion i'm using the foll. posting.

The problem is that I lose the bit depth after having done this conversion.The 
bit depth of the png image is 32 while for the bmp is 8.Is there any way to 
avoid this?
