Missing alpha on jpeg2000 options

[voxel]

jpeg2000 has no option to write alpha channel.
But if I remember correctly, this option was included in old xnview versions.
I am missing something or there is a new limitation to the format?
Thanx

Byt default the JPEG2000 plugin can't save alpha channel, perhaps it's the plugin from Luratech...

That is what I thought but I have check it and there is no alpha option in Lura...

I am pretty sure that I used this option to backup image sequences with alpha....

A poltergeist.....

I have never seen a program with alpha options for jp2k, not unless it was some official program from luratech. You can try univeiw: www.gymrk.sk/andrek/uniview It has the most options and settings out of any freeware jp2k prog.
