GDChart is an easy to use, high performance library/C API for creating charts and graphs in GIF, PNG, JPEG and WBMP format.

The GdkPixBuf library provides a number of features: - Image loading facilities. - Rendering of a GdkPixBuf into various formats: drawables (windows, pixmaps), GdkRGB buffers. - A cache interface

The exiftags utility parses a specified JPEG file or, by default, its standard input, looking for a JPEG APP1 section containing Exif (Exchangeable Image File) data. The properties contained in these data are then printed to the standard output. Digital cameras typically add Exif data to the image files they produce, containing information about the camera and digitized image. The program supports a variety of cameras, and includes additional support for a portion of the maker notes for Canon, Fuji, Nikon, and Olympus cameras.

Spencer Thomas said about the original TCL GD: Thomas Boutell's Gd package provides a convenient way to generate PNG images with a C program. If you, like me, prefer Tcl for CGI applications, you'll want my TCL GD extension. The software is now maintained by John Ellson <ellson@lucent.com>, it seems.

Geeqie is a lightweight Gtk+ based image viewer for Unix operating systems. Main features o EXIF, IPTC and XMP metadata browsing and editing. o Interoperability, easy integration with other software. o geeqie works on files and directories, there is no need to import images. o Fast preview for many raw image formats. o Tools for image comparison, sorting and managing photo collection. History Geeqie has been forked from gqview project, because it was not possible to contact gqview author and the only maintainer. Geeqie projects goal is to move the development forward and also integrate the existing patches.

The Generic Image Decoder (GID) is an Ada package for decoding a broad variety on image formats from any data stream to any kind of medium. Examples include in-memory bitmap, a GUI objecct, another stream, floating point data for scientific calculations, a browser element or a device. Animations are also supported. GID features: * Standalone; requires no other libraries or bindings * Completely portable - no OS, CPU, or compiler dependencies * Task safe * Endian-neutral * Free and open source * Pure Ada95 (suitable for Ada2005 and Ada2012 projects) Currently supports BMP, GIF, JPEG, PNG and TGA formats.

Command line assembler/disassembler of flash actionscript bytecode.

GeoAPI provides a set of interfaces from OpenGIS specifications.The development community in building GIS solutions is sustaining an enormous level of effort. The GeoAPI project aims to reduce duplication and increase interoperability by providing neutral, interface-only APIs derived from OGC/ISO Standards.
