flimp is a generic graphical frontend to the many excellent command line image manipulation tools available. It allows you to create pipelines of commands that read from standard input and write to standard output. One can view and compare the result of each stage of the pipeline. flimp leaves the input image file untouched; the pipeline is saved in a text file.
Features include
non-destructive image manipulation
easy to extend and customize
flimp is small (currently less than 2500 LOC)
import of raw images via dcraw
support for 16bit color depth
support for external GUI programs to modify parameters
