Re: Linear Colorspace

This works, with both recent ImageMagick and recent GraphicsMagick:

    #!/bin/sh

    convert in.png -depth 16 -gamma 0.454545 \
           -resize 50% -gamma 2.2 -depth 8 im.png

    gm convert in.png -depth 16 -gamma 0.454545 \
           -resize 50% -gamma 2.2 -depth 8 gm.png

GraphicsMagick 1.4 snapshot-20151101 Q16
ImageMagick 6.9.2-0 Q16
