I have an NConvert script, exported from XNView and edited (to point to the nconvert.exe and process all images in a given folder), that's supposed to create an alpha mask of the input images by extracting the alpha channel.
The correct output would look like this: (And it works, in batch processing from XNView)
Code: Select all
"Nconvert/nconvert.exe" -npcd 2 -size 256x256+0 -ctype rgb -corder inter -out png -extract "C:\MovieSprites\Mask\*.png"
Instead, NConvert is giving me this:
Which is the red channel, not the alpha channel. I looked at the output of "nconvert -help" to see if -extract could take any parameters, and it doesn't actually list the -extract option at all.
How do I make this work correctly?
[EDIT] Nevermind, installed ImageMagick and used it instead
