EZFB is a polymorphic, object oriented Linux frame buffer API written in C, designed to adapt at run time to control any properly configured Linux frame buffer video system. It offers independent, simultaneous control of multiple video cards within a single system, exceptional control of colors, the ability to display all or portions of bitmap files anywhere on the screen, automatic color depth conversion, the ability to capture to bitmap files, an 8x8 bitmapped font, routines to draw points, lines, outlined and filled rectangles, signal trapping for automatic screen clean-up at process termination, and much more. The demonstration applications include a bitmap viewer, screen capture utility, screen saver, and a touch screen calibration utility and an application for generating, viewing, transforming, and saving files according to The International Laser Display Association's ILDA file format.
Eckbox is van Eck Phreaking tool that interprets a radio signal emanating from a computer's monitor to recreate the image (in black and white) that is displayed on it. It could be used as a valuable security tool for testing otherwise secure computers or for developing hardware and software to counter this type of remote shoulder-surfing. It is not intended to be used for illegal purposes, and includes information on the hardware required.
unicap is a library to access different kinds of capture devices. Device drivers are loaded with a plugin system so that new drivers can be easily added. Currently, it has support for video-4-linux, video-4-linux-2, IIDC cameras, and video-to-firewire converters, and provides GTK widgets for live video display and access to device properties.
GL2PS is a C library providing high quality vector output for any OpenGL application. It uses sorting algorithms capable of handling intersecting and stretched polygons, as well as non manifold objects. It provides advanced smooth shading and text rendering, culling of invisible primitives, mixed vector/bitmap output, and much more. It can currently create PostScript (PS), Encapsulated PostScript (EPS), Portable Document Format (PDF), and Scalable Vector Graphics (SVG) files, as well as LaTeX files for the text fragments.
Qtpfsgui is an open source graphical user interface application that aims to provide a workflow for HDR imaging. Supported operations include: creations of a HDR file from a set of images of a scene taken at different exposure settings, tone-mapping an HDR image into a common LDR image format (e.g JPEG or PNG), and loading, saving, and rotating existing HDR images.
