/* About the ICC profile header "Platform" tag:
 *
 * When creating a profile, LCMS checks to see if the platform is
 * Windows ('MSFT'). If your platform isn't Windows, LCMS defaults
 * to using the Apple ('APPL') platform tag for the profile header.
 *
 * There is an unofficial Platform
 * cmsPlatformSignature cmsSigUnices 0x2A6E6978 '*nix'. There is,
 * however, no LCMS2 API for changing the platform when making a profile.
 *
 * So on my own computer, to replace 'APPL' with '*nix' in the header,
 * I modified the LCMS source file 'cmsio0.c' and recompiled LCMS:
 * #ifdef CMS_IS_WINDOWS_
 * Header.platform= (cmsPlatformSignature) _cmsAdjustEndianess32(cmsSigMicrosoft);
 * #else
 * Header.platform= (cmsPlatformSignature) _cmsAdjustEndianess32(cmsSigUnices);
 * #endif
 *

/* Sample command line to compile this code:
 *
 * gcc -g -O0 -Wall -o make-elles-profiles make-elles-profiles.c -llcms2
 *
 * You'll see a lot of harmless warnings about unused variables.
 * That's because I included variables for profiles that the code
 * doesn't actually make, in case you might want to make
 * these profiles for your own use.

 * ColorMatch was designed to fit Radius PressView CRT monitors,
 * similar to sRGB fitting consumer-grade CRT monitors,
 * "fit" meaning "could be calibrated to match".
 * Adobe does still distribute a ColorMatchRGB profile.
 * Making this profile using the D50_romm_doc white point that is used
 * in other old V2 profiles (ProPhoto, WideGamut)
 * doesn't make a well behaved profile,
 * but the resulting profile is very close to the Adobe-supplied version.
 * Using the prequantized primaries makes a profile that's just as close
 * to the Adobe-supplied version and in addition is well behaved.
 * Unless you have untagged images created on a PressView CRT,
 * there is no reason to make or use this profile.
