With regard to "b)", it is conceivable that the chromaticity dependent operation itself could be transformed to take into account the userRGB format description, such that the resulting transformed operation could be applied directly to the unbounded RGB data. In cases where doing so is advantageous, the implementer should have that option. The requirement should only be thatthe infrastructure produce the same result as if the operation were working in the userRGB colorspace. _______________________________________________ gimp-developer-list mailing list List address: gimp-developer-list@xxxxxxxxx List membership: https://mail.gnome.org/mailman/listinfo/gimp-developer-list List archives: https://mail.gnome.org/archives/gimp-developer-list > > a) upon import of an image the "userRGB"-format-descriptor within the images context needs to be set up to refer to the chromaticies of the source image. b) whenever a chromaticity dependent operation works on the images data the infrastructure needs to make sure that the pixel data gets fed into the operation using the chromaticies of the source image. We'll do this by having the operation request the image data in the "userRGB" format from the images context. _______________________________________________ gimp-developer-list mailing list List address: gimp-developer-list@xxxxxxxxx List membership: https://mail.gnome.org/mailman/listinfo/gimp-developer-list List archives: https://mail.gnome.org/archives/gimp-developer-list _______________________________________________ gimp-developer-list mailing list List address: gimp-developer-list@xxxxxxxxx List membership: https://mail.gnome.org/mailman/listinfo/gimp-developer-list List archives: https://mail.gnome.org/archives/gimp-developer-list
