Description:
FITS to PNG converter
Fitspng is an utility intended to convert of the natural high dynamic range of FITS images, directly representing measured data, to the limited numerical range of PNG format widely used in computer graphics. Fitspng implements a global tone mapping technique by a set of tone functions using parameters provided by user or by machine estimate on base of a robust count statistics. Moreover, the conversion keeps an important FITS meta-information as a text part of PNG header.
