Detailed Description

A struct that describes how to transform FITS pixel values.

The pixel values represent the lower and upper boundaries of the pixel data from the FITS file. The data values represent the range of the final pixel values. For example, to transform FITS pixel values to grey scale, the data min is 0 and data max is 255. The transformation is linear.
