[Magick-bugs] Calculating in linear colorspace

[Ilya Zakharevich]

I want to make certain transformations to an sRGB file, but I want the
transformation to be performed in the linear colorspace.  I suspect it
can be done with -colorspace option, but unfortunately, it is not
documented...

So: how to do a moral equivalent of

  convert from.png -linear-from sRGB -blur 4x4 -linear-to sRGB output.png

?

Thanks,
Ilya
