Open Tool Kit (Otk) is a portable widget library for making graphical user interfaces for C programs. It emphasizes simplicity for the application programmer without eliminating capability. Based on OpenGL, Otk supports Linux, Unix, and other OSs neutrally and efficiently. It is simple and compact, and it strives for easy compilation and linking to other applications. In seeking to address several issues associated with earlier graphics APIs, Otk explores some interesting methods, such as window-relative layout instead of pixel-based layout.
tvpvrd is a PVR daemon for Linux that offers the ability to schedule and manage TV recordings using one or multiple installed analogue TV capture cards, e.g. Hauppauge. The daemon is interfaced either through its full command language via a provided command line shell or through a basic (built-in) Web interface provided by the built in micro Web server. The goal is to provide an advanced recording and transcoding (using ffmpeg) server without the need to configure databases or a complex GUI. The server is completely self-contained and uses an XML DB in plain text format to store future recordings.
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.
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.
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.
