Colour Management Tests
Colour Management Tests
Project Description
Write reftests to compare images. This includes dealing with things like Monitor Profiles, profiles in JPEG (i.e., JPEGs get changed based on colour profile info). See discussion of colour profiles in Firefox 3 here. It would be useful to be able to compare to PNGs with a reftest, perhaps creating an image diff tool, where pixels outside a floating point tolerance (> 0.n) would somehow be highlighted so you can see what is different. Done.
This will require some graphics and image knowledge (i.e., Photoshop, what colour is on a computer, etc).

1
Have a build of firefox on the linux with
ac_add_options --enable-tests
on the mozconfig
2
download the reftest
contrib-failedtest
unzip it in your home folder.
open terminal
and
cd ~/pngsuite-colorprofiles-failedtest
run the reftest
~/pngsuite-colorprofiles$ ~/src/obj*/dist/bin/firefox --no-remote -reftest -P testfirefox1(replace with test Profile) ./failedPixelTestAdobe1998.list | grep REFTEST > failedPixeltestAdobe1998output(insert Linux OS).txt
3
open the failedPixelAdobe1998output*.txt
Outcome:
It should failed and it should have
the URI data of the tested pixels/images.
see
'fail line output'

Project Details
0.1 Release Isolated Failed test. failedtests0.1
TechNote001: Reftest framework contains image rendering reftests in module/libpr0n/test/reftest inside the mozilla source.
Technote002:
about:config and set
gfx.color_management.mode to
‘0′ for no color management,
‘1′ for full color management, and
‘2′ (the default) for tagged(with ICC)-only correction
Technote003: What are ways to embed colour profiles into images? Photoshop does it. Preview in Mac OSX does it which means you can use Automator to apply profiles on multiple images
Technote005:
reftest can compare images now output is sRGB if the reftest fails
Technote007: Use URI scheme for reftest DATA URI Scheme Wiki
Techtool002:

Reading on colours LAB vs RGB vs CMYK
Has a conclusion on the ubuntu
Update the test updated tests
- Oct 11/08
spent time isolating 2 pixels that were failing on the reftests in Ubuntu tested to see if the suspected pixels were failing...yes they still fail.
simplified reftest to show failing pixel and reftest differences in GIMP
- Oct 12/08
filed a bug bug#459617
trying to narrow it down.
- Oct 19/08
how to test in different configurations.
