ICC Examin 1.0 on Android

ICC Examin allows since version 1.0 ICC Color Profile viewing on the Android mobile platform. ICC Examin shows ICC color profile elements graphically. This way it is much easier to understand the content. Color primaries, white point, curves, tables and color lists are displayed both numerically and as graphics. Matrices, international texts, Metadata are much easier to read.

Features:
* most profile elements from ICC specification version 2 and version 4
* additionally some widely used non standard tag are understood

ICC color profiles are used in photography, print and various operating systems for improving the visual appearance. A ICC profile describes the color response of a color device.

The ICC Examin App is completely rewritten in Qt/QML. QML is a declarative language, making it easy to define GUI elements and write layouts with fewer code. In recent years the Qt project extended support from desktop platforms to mobiles like Nokias Meego, Sailfish OS, iOS, Android, embedded devices and more. ICC Examin is available as a paid app in the Google Play Store. Sources are currently closed in order to financially support further development. This ICC Examin version continues to use Oyranos CMS. New is the dependency to RefIccMAX for parsing ICC Profile binaries. In the process both the RefIccMAX library and the Oyranos Color Management System obtained changes and fixes in git for cross compilation with Android libraries. Those changes will be in the next respective releases.

The FLTK Toolkit, as used in previous versions, was not ported to the Android or other mobile platforms. Thus a complete rewrite was unavoidable. The old FLTK based version is still maintained by the same author.

Firefox-19.0 Colour Management

Firefox detects since version 17.0 the Linux system profile, which is a great improvement for the operating system. While colour conversions on all platforms still default to on for ICC tagged content, they can be enabled for all other colours. Untagged colours will then default to sRGB instead of omitting monitor compensation for them. To do so go to the famous about:config URL and change gfx.color_management.mode from “2″ to “1″. Then use the installed CMS, e.g. on  KDE KolorManager, to set a system monitor profile, and it will be detected after restarting Firefox.

For Android there is no CMS available. That means the ICC monitor profile must be set manually or sRGB will be assumed instead. The settings name in about:config is gfx.color_management.display_profile. Enter into this string the file name with full path, if you are on Android. That procedure is somewhat inconvenient compared to desktops. However the OpenICC group has published some specifications for implementation. This might be even possible for students inside the rewarding Google Summer of Code 2013 program.

For comparison, the Chrome web browser does support colour management on some desktop versions but unfortunately not on Android.

The below false colour test image should look correctly with ICC profile enabled browsers. Look at the colour gradients and then at the colour names and compare.
