icc-v4.jpg is Meta/Websites/serenityos.org/happy/3rd/bgianf.jpg.
There are a whole bunch of jpgs with v4 color profiles and I just picked
one fairly arbitrarily. It looks like a fairly standard v4 matrix
profile that in this form is also present in many jpgs taken by mobile
phone cameras. It uses parametric curves.
icc-v2.png is based on ./Documentation/WebServer_localhost.jpg since
that is the only image in the repo with a v2 color profile. It also has
all kinds of interesting and somewhat exotic tags, such as an 'dscm' (an
Apple extension to have a description of type 'mluc', since normal
'desc' is required ot have type 'desc' in v2 files -- in v4, 'desc' has
type 'mluc') tag of type 'mluc' that actually contains data in several
languages and that exercises the non-BMP UTF-16BE decoder. It's however
still also a fairly standard v2 matrix profile, which uses 'curv'
instead of 'para' for its curves ('para' is v4-only).
I converted that jpeg file to png, and cropped most of the image
data to save on file size by running:
sips -s format png --cropToHeightWidth 21 42 in.jpg --out out.png
Rather than reading files out of /res, put them in a subfolder of
Tests/LibGfx/ and pick the path based on AK_OS_SERENITY.
That way, the tests can also pass when run under lagom.
(I just `cp`d all the files that the test previously read from
random places into Tests/LibGfx/test-inputs.)
