Hi all,

I get some JPEG data from the network.  I want to efficiently decompress this 
data into a specific format (8 bit greyscale) and have an NSData of the raw 
pixels.  What's the best way to do this?

I'm currently using NSBitmapImageRep initWithData:, then testing if the result 
is greyscale or RGB.  If the latter, I write my own loop to convert to 
greyscale.

But I'm hoping there is some lower level API available that I can tell 
explicitly that I want greyscale...

Thanks,

--
