Gmagick is a PHP extension to create, modify, and obtain meta-information of images using the GraphicsMagick API. GraphicsMagick prides itself as the swiss army knife of image processing. It works with over 88 major formats including DPX, GIF, JPEG, JPEG-2000, PNG, PDF, PNM, and TIFF. Gmagick consists of a main Gmagick class, a GmagickDraw class that is in effect a drawing wand, and a GmagickPixel class of which instances represent a single pixel of an image (color, opacity).
Graylog2 is an syslog implementation that stores logs in MongoDB. Messages are accepted via TCP or UDP. A Web interface allows you to view the log messages. It also implements GELF, the Graylog Extended Log Format, which is a simple JSON string that allows you to send long and structured syslog messages, which is very useful for customized application log monitoring.
The primary aim of the Gtk+2 panel project is to provide a panel that reuses whatever is available (if it is not overkill) in the obvious way, such as subclassing GtkWidget instead of implementing applets, or by using a GtkBuilder file instead of defining a new format to customize the panel. This approach gives some additional advantages for free: you can use common tools in uncommon ways. Above all, you can use Glade to design your own panel. All the dependencies apart from GTK+ are (and hopefully will be) optional.
JsonRpcPhp is a class that sends HTTP requests to a given JSON RPC server to call a specified function, passing any additional parameters. It can also send multiple JSON RPC requests and return the results of all calls. Another class can process server requests by registering a given object of service class and dispatching requests to be handled by that object.
