Balancing Image Colour,An image shows neutral colour balance if its mean value is mid-grey (127, 127, 127). In general, an image shows some degree of colour imbalance, but it can be brought into balance by changing the colours proportionately, or by framing. This chapter presents scripts for colour balancing an image by both methods, and examples.

Digital Imaging Fundamentals,delled as a coordinate cube. A digital image has a complete numerical representation as a width and a height in pixels, followed by a scan sequence of colour triples. This numerical representation can be created, stored, transformed, displayed, printed and transmitted by computer. The location resol

Transforming Image Locations,are cropping, framing, dilating, translating, rotating, shearing and inverting. These can be done by suitable packaged software or purpose-written scripts. The transformed image is returned to storage.
