The same happens with pix_2grey.
If I understand correctly, while pix_grey changes the colorspace,
pix_2grey actually computes the color values to convert the image to
grey without changing the color space.
I had a look at the source code and the weight factors for converting
RGB to grey seem correct, they do sum to 256, so it's really strange
that white becomes 86% grey........

Hi list,
Before I file a bug report (and since it seems strange that it hasn't
been reported already), I though I'd check if I'm missing something:
why in the attached patch isn't the white white? That is, after
converting with [pix_grey], white becomes a bit darker. Seems like some
factor in the conversion is wrong.
Or am I missing something?
Is there any easy workaround?
thanks
m.
