Hmm, my apologies, I might have mixed up the "to-from" commands in the initial email. I checked conversions going from linear gamma to gamma=2.0 and also going from gamma=2.0 to linear gamma. From linear gamma to gamma=2.0: transicc -c0 -t1 -w -i sRGB-V2-g10.icc -o sRGB-V4-g20.icc LittleCMS ColorSpace conversion calculator - 4.2 [LittleCMS 2.06] Enter values, 'q' to quit R? 255 255 0 G? B? R=255.0000 G=255.0000 B=0.0134 From gamma=2.0 to linear gamma: transicc -c0 -t1 -w -o sRGB-V2-g10.icc -i sRGB-V4-g20.icc LittleCMS ColorSpace conversion calculator - 4.2 [LittleCMS 2.06] Enter values, 'q' to quit R? 255 255 0 G?

The only difference is the naming convention. Elle ------------------------------------------------------------------------------ Want excitement? Manually upgrade your production database.
