There is disclosed a system and method for interpreting and describing graphic images. This enables optimizing complicated raster operations using applications, both in output size and drawing quality, and correct drawing even with non-supporting page description language systems. The system further can include a connection manager programmed for coupling to the connection pool. The deflected light is retained by means of at least TIR in the system formed by the optical cover and the light harvesting device which allows for longer light propagation paths through the photoabsorptive layer of the device and for an improved light absorption.
