I need to save files to other formats like RGBA 4444 not RGBA 8888. As I tested, normal Gimp (without proper plugin) can't save a file with that format. I saw one plugin could do the job which is <a class="postlink" href="https://github.com/jeffboody/texgz" onclick="window.open(this.href);return false;">https://github.com/jeffboody/texgz</a> but I can't manage to install it due to it requires gimptool which I don't have. Due to I don't build gimp from source. Although I even tried building from source once but no success, and I am prefer to do that way again. Can anyone suggest me another way around to make texqz plugin work on 2.8.2 Gimp (i'm on OS X Lion 10.7.5)? or Any suggestion on plugins related to do this kind of task?
