LMS color space <--> RGB

[BUG]

Zitat von WojTec:

After multiplication 3x3*3x1 I'll get another 3x3 matrix

No way Just do a matrix multiplication.

Yes, of course, my mistake

I have this:

Delphi-Quellcode:

var
  L, M, S: Double;
  XYZ: TXYZ;
begin
  XYZ := RGBToXYZ(RGB(130, 113, 222));
  L := (0.4002 * XYZ.X) + (0.7076 * XYZ.Y) + (-0.0808 * XYZ.Z);
  M := (-0.2263 * XYZ.X) + (1.1653 * XYZ.Y) + (0.0457 * XYZ.Z);
  S := (0 * XYZ.X) + (0 * XYZ.Y) + (0.9182 * XYZ.Z);
  ShowMessage(Format('%f %f %f', [L, M, S]));
  // 20,97 22,32 65,95
end;

Now I'll try make reverse transformation.

I did and it working

Just another question, how matrixes from Wikipedia was computed?
