ExactImage is a fast imaging library including a command line frontend.
exiftran is a command line utility to transform digital image jpeg images.
It can do lossless rotations like jpegtran, but unlike jpegtran it cares
about the EXIF data: It can rotate images automatically by checking the exif
orientation tag, it updates the exif informaton if needed (image dimension,
orientation), it also rotates the exif thumbnail.
It can process multiple images at once.

FotoFix is a simple image viewer with simple capabilities to take care
of freshly downloaded photos from your camera - can walk image lists,

GDChart is an easy to use, high performance library/C API for creating charts
and graphs in GIF, PNG, JPEG and WBMP format.
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.
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.
gexiv2 is a GObject-based wrapper around the Exiv2 library. It makes the
basic features of Exiv2 available to GNOME applications.
