2020-04-25 Thread Carl Eugen Hoyos
Hi! Attached patch makes the output of the reference sample p0_03.j2k bit-exact with opj_decompress and kdu_render and more similar to jasper's output. Please comment, Carl Eugen From de80453a8decd95b4a71cea71b20ba0bd74485cb Mon Sep 17 00:00:00 2001 From: Carl Eugen Hoyos Date: Sat, 25 Apr 2020
