This may be a stupid question but...

When converting 8bit/pixel color to 5bit/pixel color, are any side effects
introduced if the top 5 bits are used (c >> 3)?  How about converting the
other way, say 3bit/pixel -> 5bit/pixel?  Are there more efficient ways
of doing this?

A related problem:  Is there a better way to correctly increase the intensity
of a pixel than
        hsv  = RGB2HSV(rgb)
        v += intensity difference
        rgb' = HSV2RGB(hsv)

Any help would be appreciated.  Mail should be directed to ks26+@andrew.cmu.edu

Thanks,
