> 3770JPEGDecoder-ar -- Andreas Raab -- 4 March 2001
> Several improvements for JPEG reading. Provides a plugin for three critical methods in the decoder speeding things up roughly by a factor of 15 (there is probably another speedup of 2-3 in the prims itself but right now I can't be bothered to go looking for it). Even the simulated version is about 10% faster. Test results against a 1280x1024 picture resulted in:
> Old: 	56 seconds.
> New: 	49 seconds (without plugin)
> 		3.3 seconds (with plugin)
> Also provides primitives for reading 32bit signed integers from word-indexed objects (e.g., IntegerArray). The above values were based on a VM that *did* have those primitives; otherwise the results of the simulation would be WAY slower.

Thank you, thank you, thank you!

Is this plugin going to be available seperately, or will it be built in?
 (And can I vote for built in, please?)

:)
