Segmented read

Hi,

Does anyone knows if it's possible to use the current version of the 
jbig2dec API to read a jbig2 image segment by segment like if it was a 
stream?
What I really want to avoid is to allocate one gigantic buffer 
containing the totality of the image (stripe*height) because in my case 
it means allocate hundred of megabyte, maybe, in extreme case, more than 
the RAM.

Thanks for any suggestion.

Eric
