I could easily create the required custom test chart and take the measures but I have a ti3 file with XYZ values and I need RGB values. Is there an easy way to convert my 256 XYZ coordinates into RGB format? The target color space is Rec709 (sRGB primaries and D65 white), I think...
You can use xicclu to convert a series of XYZ values to device values. Typically you would open the .ti3 in a spreadsheet, and cut and paste to a text file, to be redirected into xicclu. You would need a Rec709 profile though. Perhaps lcms can be used to construct such a profile, if one is not available. Graeme Gill.
