Maxwell Technologies
From ColorWiki
CHROMiX Maxwell draws on a wide range of technologies. This page summarizes those technologies for those interested in Maxwell's underpinnings or who are working on supporting Maxwell through API communications. Most technologies below are not of CHROMiX construction but a few are.

Color Science
Spectral Data
Colorimetric Data
- At this time, XYZ and Lab values in Maxwell are calculated for D50 and 2 degree observer. Emissive colors for displays and illuminants may be based on a non-D50 white point but will be adapted to D50 for color differencing equations in most cases.
- Maxwell has the ability to specify and adapt to/from varying white points and we will be exposing more of these capabilities in future upgrades.
Densitometric Data
Color Differencing
Communications
Web Communications
- Maxwell uses HTTP and HTTPS for all web browser and API communications. HTTP(S) was chosen to allow easy communication through corporate firewalls, proxy servers and other security systems. All CHROMiX applications that communicate with Maxwell do so through HTTP(S).
Data Structures & Formats
Color FIle Formats
- CGATS
- ASCII-based color measurement files
- CXF
- Color eXchange Format
JSON
Meta Data Handling
Dates and Times
- Maxwell is international time aware and stores all dates in UTC form. Unless translated explicitly by Maxwell through an API or the web interface, all times will be in UTC (GMT).
- For the web interface, Maxwell automatically detects the time zone configured in the user's web browser - which typically is directly drawn from the user's operating system settings. All dates in Maxwell's web interface are displayed in the user's local time zone unless otherwise directed by the user.
