could RVIO do resize *.exr with retention all of the extra channels ?

rvio exr.exr -scale 0.5 -o half_exr.exr

produce exr only with RGBA channels.

mybe exist some way to do something like:

rvio exr.exr -scale 0.5 -outchannelmap all -o half_exr.exr

  Hi Robo,

  No, sorry, at the moment, the rvio pipeline is limited to 4 channels.  You can use -inchannelmap and -outchannelmap to map to and from those 4 channels, but that's it for now.

  For example

  rvio myexr.exr -inchannelmap GI.R GI.G GI.B A -o new.exr
  

  will map those channels to RGBA in the output, and

  rvio myexr.exr -inchannelmap GI.R GI.G GI.B A -outchannelmap GI.R GI.G GI.B A -o new.exr

  will map them back to their original names, but other channels in the input image will be lost.
