Re: [Lcms-user] Question about sRGB and rendering intent

[Aaron B. <bo...@gm...>]

Thanks, Noel. I have no idea how the images will eventually be viewed.
I just don't want any color management information lost when the images are
compressed.
So, since I don't know how the images will be rendered, I guess it makes
sense
to suppress the origin perceptual rendering intent.
