Here's a comparison of a JNG file with uncrompressed exIf
and compressed zxIf chunks:

glenn.rp>pngcheck *.jng
OK: canon_e135_exIf.jng (1152x864, 8-bit YCbCr, 89.3%).
OK: canon_e135_zxIf.jng (1152x864, 8-bit YCbCr, 90.3%).

glenn.rp> ls -l *.jng
-rw-rw-r-- 1 glennrp glennrp 106438 Jan 31 17:40 canon_e135_exIf.jng
-rw-rw-r-- 1 glennrp glennrp  96950 Jan 31 17:33 canon_e135_zxIf.jng
