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. flimp features non-destructive image manipulation, 16bit color depth, and import of raw images via dcraw, and is easy to extend and customize.
flimsel is a minimalistic digitial image browser based on the fltk toolkit. It displays thumbnails of images given on the command line. It is intended to be used in digital image processing shell scripts. flimsel uses the very fast epeg library for JPEG thumbnail generation. flimsel outputs keyboard hotkeys and file names of selected images to stdout. Images whose filenames are written to stdin will be reloaded. The flimsel.sh script in the examples directory uses this to implement basic image manipulations on selected images.
flpsed is a WYSIWYG PostScript annotator. You can't actually edit existing documents, but you can add arbitrary text lines to existing documents. Added lines can later be re-edited with flpsed. Using pdftops, flpsed can import PDF documents and also add text to them. It is useful for filling in forms, adding notes, etc. In batch mode, it can be used to automate form filling.
gipfel is a tool to find the names of mountains or points of interest on a picture. It uses a database containing names and GPS data. With the given viewpoint (the point from which the picture was taken) and two known mountains on the picture, it can compute all parameters needed to compute the positions of other mountains on the picture. gipfel can also generate (stitch) panorama images.
nmzmail is a tool to use the namzu2 search engine from within the Mutt email reader to search email stored in maildir folders. Based on the result of the namazu query, nmzmail generates a maildir folder containing symbolic links to the messages matching the query. A simple Mutt macro makes it easy to use from within Mutt.
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.
