Hi I'm using colprof (with option -am) and profcheck for profiling a scanner using Kodak IT8 chart, and xicclu for color space conversion. According to the generated profile, the rendering intent is relative colorimetric as I would like to have. So I would expect that the RGB to Lab values in the profcheck file is based on relative colorimetric rendering. But when I use the xicclu (with option -ir), I get different results; while xicclu (with option -ia) gives the same result as obtained in tge profcheck file. Now I am confused, if the rendering intents mean different for colprof and xicclu or something else. Answers please! Here is an example from the profcheck file, which matches with xicclu -ia:GS00: 0.489090 0.514540 0.490160 -> 90.990517 -1.809602 -0.769897 should be 91.315673 3.477132 0.326901 Here is the result from xicclu (with option -ir):0.489090 0.514540 0.490160 [RGB] -> MatrixFwd -> 100.000116 -0.000804 0.000767 [Lab] prarthana
