# WhitePoint, if RGB, points to chromaticity of the white point of the image.This is the chromaticity
# when each of the primaries has its ReferenceWhite value. The value is described using the 1931 CIE
# xy chromaticity diagram and only the chromaticity is specified. This value can correspond to the
# chromaticity of the alignment white of a monitor, the filter set and light source combination of a
# scanner or the imaging model of a rendering package. The ordering is white[x], white[y].
# (Source: www.awaresystems.be)
# example: CIE Standard Illuminant D65 used by CCIR Recommendation 709 and Kodak PhotoYCC is:
# 3127/10000,3290/10000

# PrimaryChromaticities, This is the chromaticity for each of the primaries when it has its ReferenceWhite
# value and the other primaries have their ReferenceBlack values. These values are described using the
# 1931 CIE xy chromaticity diagram and only the chromaticities are specified. These values can correspond
# to the chromaticities of the phosphors of a monitor, the filter set and light source combination of a
# scanner or the imaging model of a rendering package.
# (Source: www.awaresystems.be)
# The ordering is red[x], red[y], green[x], green[y], blue[x], and blue[y].
# For example the CCIR Recommendation 709 primaries are:

Ordinarily, however, it does not contain image data as in the case of TIFF.
