Detailed Description
The class is used in three different cases:- As a base for pixel values, in which case it instantiates into a set of channel values whose relative ordering is specified by the color base
- As a base for the proxy class representing a reference to a planar pixel, in which case it instantiates into a set of channel references
- In the construction of planar_ptr, the proxy class representing a pointer to a planar pixel, in which case in instantiates into a set of channel pointers
Color bases also provide color-space independent accessors to the channel values/references/pointers, which allows us to perform color-space-independent channel operations (see pixel_base for more).
color_base specializations are provided for each color space. See concrete specializations for more.
