Error on lossy jbig2 encoding #73

Hi,

With lossy compression I get error result, the image in the attached file missing some paths.
the attached file is as follows:
0005707_spring hill00021.pdf

The encoding result is as follows: the original image on the left and the resulting image on the right.
This is the result of reversing image data and then doing JBIG2 compression.
Jbig2_FirstResverDataThenEncoding.pdf
jbig2

If the image data is not reversed, jbig2 encoded results processed by PDF decode are as follows:
Jbig2_NoResverDate.pdf
image
image

I do not now how to deal with it. Any help will be very much appreciated.
