[Insight-developers] BMPImageIO

[Marius Staring]

Hi Julien,

thanks for the fix. Everything works for me now.

One other thing: there is this boolean m_Allow8BitBMP in the code, which 
is not accesible by a user and is always true. You probably can get rid 
of it, or am I missing something?

Thanks again,

Marius
