Hi,
I have a question about the lcms1 and lcms2 sRGB profiles.
The code for the built-in sRGB profile in cmsvirt.c looks essentially
the same for lcms1 and lcms2. The unadapted xy primaries are
identical:
cmsCIExyYTRIPLE Rec709Primaries = {
{0.6400, 0.3300, 1.0},
{0.3000, 0.6000, 1.0},
{0.1500, 0.0600, 1.0}
};
The lcms1 sRGB profile (http://www.littlecms.com/1/downloads.htm) has
the following RGB XYZ primaries:
0.43607 0.22249 0.01392
0.38515 0.71687 0.09708
0.14307 0.06061 0.71410
For lcms2, is there a difference in the final (built-in) sRGB RGB XYZ
primaries? Or is the lcms2 sRGB profile exactly the same as the lcms1
sRGB profile? I realize that lcms2 now uses V4 by default. But if one
asks for a V2 sRGB profile (is the built-in V2 or V4?), is it the same
profile that was produced by lcms1, at least as far as the XYZ RGB
primaries go?
