Not able to compress volumetric data

[abhigarhia]

I have created some z-stack images (pgx) and trying to compress it with opj_jp3d_compress. It is loading and compressing only first image from the stack.
I am using the below command. The folder got 4 .pgx files.

./opj_jp3d_compress -o output.jp3d -r 1,1,1,1 -i relative_path/img_*.pgx
