Hi,

I tried ImageMagick: http://www.imagemagick.org

convert -depth 16  bmptest24.bmp bmptest16.bmp
"This is the number of bits in a color sample within a pixel. The  
only acceptable values are 8 or 16. Use this option to specify the  
depth of raw images whose depth is unknown such as GRAY, RGB, or  
CMYK, or to change the depth of any image after it has been read."

and out comes the following different but still readable bmp:

No idea how to convert that into 32 bits though.

Hope that helps,

Markus
