Adding Profiles

This page describes the internals of YUVColorTypes.jl.

You can implement the conversion methods such as convert_yuv_to_rgb directly. However, except in the case of nonlinear conversions or speed optimization, the conversion processes are completed simply by defining a profile.

RGB color primaries and whitepoint

YUVColorTypes.primary_r — Function

primary_r(C) -> xyY{Float64}

Return the red primary of color type C in xyY where Y is 1.0.

YUVColorTypes.primary_g — Function

primary_g(C) -> xyY{Float64}

Return the green primary of color type C in xyY where Y is 1.0.

source

YUVColorTypes.primary_b — Function

primary_b(C) -> xyY{Float64}
