The file with data:

The calculator takes the files *.txt, *.cxf, *.ti3, *.icc, *.icm, *.lxf, *.dpxf, *.dmxf, *.xml and no larger than 2 megabytes. Files can contain both spectral and colorimetric (XYZ, Lab, LCh) data for the calculation of chromatic adaptation and TVI. The correct formatting of the native data of this CGATS calculator and data for parsing CxF can be viewed by clicking the buttons with examples below, or by clicking the link. Processing of ICC files can take from 6 to 60 seconds. The presence of foreign characters (spaces, commas, points, etc.) in the filenames that do not refer to letters and numbers in the Latin layout can lead to an error reading data from such a file.
