Image Representation

The Wolfram Language's symbolic architecture allows a unique representation and treatment of images in both programs and documents. The Wolfram Language supports images with arbitrary numbers of channels and arbitrary color depths, and with a full range of internal data types either specified explicitly or chosen automatically.
