exr all channl to jpg command line

how to write a command line Batch converting all channl of EXR to jpg?

[tashko.zashev]

Hi,

Unfortunately there is no batch command that will export all EXR channles to separate JPG files. This could be done with specifying all EXR channels one by one.

Here is one example for single channel export:
C:\Program Files\Pdplayer 64>pdplayer64 C:\file0000.exr --image_layer="VRayLighting" --save_layer_as=c:\File.jpg --exit

And another one for multiple channels export:
C:\Program Files\Pdplayer 64>pdplayer64 C:\Users\Chaos\Desktop\file0000.exr --image_layer="VRayLighting" --save_layer_as=c:\File.jpg --image_layer="VRayDiffuseFilter" --save_layer_as=c:\File_2.jpg --exit

You can get them from the scene file, Maya or Max, but in case that if you don't have it, you can use Pdplayer > Expand into Layers option.

Unfortunately there is no way to list all EXR layers in the command line window.
You can get them using the Pdplayer GUI or Nuke for an example.

You can use the exrheader tool which is part of the OpenEXR library.
