We had released ofxKuNetwork addon for openFrameworks, which allows to transmit raster images and arbitrary arrays, as well as integer and float values over network using TCP protocol.

The addon’s code is improved version of our internal code which we used and debugged for a long time in our interactive installations.

Addon is based on ofxNetwork addon, so compiles pretty nice in clean openFrameworks. It contains example of usage it for transmitting raster image.
