Here are some examples: These messages are debug messages, informing us that GIMP tried to create dedicated babl_formats from the ICC profiles, babl detected that it is a type of ICC profile it is not capable of handling, thus GIMPs attempt at creating a babl based format (and thus conversions) failed. GIMP will then instead use lcms2 for conversions to/from the color space of the ICC profile. The same happens when GIMP tries to rig up conversions to/from a color space in its perceptual intent instead of relative colorimetric *and* perceptual intent is defined with 3D CLUTs in the ICC profile, babl gives up, GIMP notices, and uses lcms2 instead of babl for conversions. If when/additional capabilities get added to babl GIMP will automatically be using babl for more conversions. Calling this an error isn't entirely correct though, it should be a warning. /pippin _______________________________________________ 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
