Projects / pnmcurve


pnmcurve is a command line tool that applies tone curves to pnm images. Curves are specified as a set of control points of a cubic spline. pnmcurve applies the resulting spline curve to the pnm image read from stdin and writes the resulting image to stdout. Command line switches allow the user to apply the curve only to selected color channels. A separate FLTK-based graphical curve editor helps to set the control points.
