PixelFormat
Specifieds a particular format of an archetypes.Image.
Most images can be described by a datatypes.ColorModel and a datatypes.ChannelDatatype,
e.g. RGB and U8 respectively.
However, some image formats has chroma downsampling and/or
use differing number of bits per channel, and that is what this datatypes.PixelFormat is for.
All these formats support random access.
For more compressed image formats, see archetypes.EncodedImage.
