luma(c)

Return the luma component of a YUV-like color. To avoid confusion, this function does not support ColorTypes.YCbCr and its variants, which are not under the AbstractYUV.

chroma_u(c)

Return the first chroma component of a YUV-like color.

chroma_v(c)

Return the second chroma component of a YUV-like color.

chroma_b(c)

Return the Cb component of a YCbCr color. For general YUV-like colors, use chroma_u. To avoid confusion, this function does not support ColorTypes.YCbCr and its variants, which are not under the AbstractYUV.

chroma_r(c)

Return the Cr component of a YCbCr color. For general YUV-like colors, use chroma_v. To avoid confusion, this function does not support ColorTypes.YCbCr and its variants, which are not under the AbstractYUV.

chroma_g(c)

Return the Cg component of a YCgCo color. For general YUV-like colors, use chroma_u.

chroma_o(c)

Return the Co component of an YCgCo color. For general YUV-like colors, use chroma_v.

rgb_to_yuv(C, rgb::AbstractRGB) -> C
rgb_to_yuv(C, argb::TransparentRGB) -> C

Convert an RGB color to a YUV color. The color primaries, whitepoint and gamma are depends on the YUV color type. If you need sRGB colors, use yuv_to_srgb or simply use convert or RGB constructors.

See also srgb_to_yuv and yuv_to_rgb.

srgb_to_yuv(C, rgb::AbstractRGB) -> C
srgb_to_yuv(C, argb::TransparentRGB) -> C

Convert an sRGB color to a YUV color.

See also rgb_to_yuv and yuv_to_srgb.

yuv_to_rgb(C, yuv::AbstractYUVColorant) -> C

Convert a YUV color to an RGB color. The color primaries, whitepoint and gamma are depends on the YUV color type. If you need sRGB colors, use yuv_to_srgb or simply use convert or RGB constructors.

See also yuv_to_srgb and rgb_to_yuv .

yuv_to_srgb(C, yuv::AbstractYUVColorant) -> C

Convert a YUV color to an sRGB color.

See also yuv_to_rgb and srgb_to_yuv.
