XnView Software

trying to get levels command to work but havfing trouble here. i use
nconvert with a script. here's an example of my command line:

C:\Program_O\XnView\nconvert -out $outformat -log -high_res -raw_camerabalance -negate -levels $corrLvlToe $corrLvlShd -brightness $corrBri -contrast $corrCon -gamma $corrGam -balance $stepA $stepB $stepC -HLS $corrHue $corrLtn $corrSat -crop $cropX $cropY $cropW $cropH -resize $resizeW $resizeH -o $outname $wdgfile

this line works fine without the '-levels $corrLvlToe $corrLvlShd' bit.
obviously there are a lot of variasbles in the line. they all seem to be
accepted without issue from nconvert, though, with the exception of the
levels command and its variables. all i get with this line is a white frame.

could someone please clarify for me how to use the levels command in a
script?

here's a shorter version of my command line to make it easier to see
how i'm using levels:

C:\Program_O\XnView\nconvert -out $outformat -levels $corrLvlToe $corrLvlShd -o $outname $wdgfile

levels seems to work fine for me in xnview also. i just can't get it to work
in nconvert.

thanks,
