CL spec specifies that the color values for different types of channel orders as below.
CL_R, CL_Rx (r, 0.0, 0.0, 1.0)
CL_A (0.0, 0.0, 0.0, a)
CL_RG, CL_RGx (r, g, 0.0, 1.0)
CL_RA (r, 0.0, 0.0, a)
CL_RGB, CL_RGBx (r, g, b, 1.0)
CL_RGBA, CL_BGRA, CL_ARGB (r, g, b, a)
CL_INTENSITY (I, I, I, I)
CL_LUMINANCE (L, L, L, 1.0)

In case of write_image(f|i|ui) functions what would happen is the pixel values are not exactly in the format as shown above?
Ex:
for pixel value of
CL_INTENSITY (a, b, c, d)
CL_R, CL_Rx (r, a, b, 1.0)

Should the spec specify any conversion rule for this kind of values or its users responsibility to use correct color value?

thank you.
