    GEM - Graphics Environment for Multimedia

    normalize a pixBuf, so that the values are not between min..max but between 0..255
    MIN=min{R,G,B} and MAX=max{R,G,B} of all the pixBuf

CLASS
    pix_normalize
    
    Change the overall gain of a pix

KEYWORDS
    pix
    
DESCRIPTION

    Inlet for a list - "vec_gain"
    Inlet for a float - "ft1"

    "vec_gain" - The gain vector to set to
    "ft1" - Which bit to use as a mask (converted to an int)
