Скорее всего вам нужно воспользоваться программой ScanKromsator. Поищете его на руборд.ком.
Также существуют консольный бинаризатор входящий в Potrace (MKbitmap) potrace.sourceforge.net

There was a problem in version 7.154 with using "-l file : Use file as filelist".
nconvert.exe -recurse -quiet -out pdf -multi -c 1 -binary nodither -l "C:\temp\1.txt" -o 1.pdf
File "C:\temp\1.txt" contains filelist:
C:\MyDocs\20230824_180749.jpg

Thank you very much for the implementation recurse.
I found the small bug: if filename contains a dot (for example: IMG.6736.JPG or 04.12.2021.JPG), then file will be saved without extension (IMG.6736 or 04.12.2021).

попробуйте в cmd файле перед обращением к nconvert добавить эти строки:
try to add this strings:
@echo off
chcp 1251 > nul
.\nconvert.exe -canvas #0 #150 bo....

Я схожую необходимость решил следующим решением:

@Echo Off
SetLocal EnableDelayedExpansion
Set DataRoot="%1"
Set OutFile=out.txt
chcp 1251 > nul
For /F "delims=" %%A In ('Dir "%DataRoot%\" /B /A-D 2^>nul') Do (Echo %%~fA>>"%OutFile%")
For /F "delims=" %%A In ('Dir "%DataRoot%\" /S /B /AD') Do ...

Thanks.
This method is working.
But it significantly increases the processing time. And most likely double conversion in jpeg reduces image quality.

In XnView batch converter double canvas resize works properly.
Export to bat contains with code:
nconvert -npcd 2 -size 256x256+0 -ctype rgb -corder inter -out jpeg -bgcolor 0 0 0 -canvas 101%% 101%% center -bgcolor 255 255 255 -canvas 102%% 102%% center

i need to make border (1 px black line + 7 px white line for each side) for resized image.
i try to use this code:

"C:\XnView\nconvert.exe" -quiet -out jpeg -ratio -rflag decr -resize longest 1328 -rtype lanczos -bgcolor 0 0 0 -canvas #2 #2 center -bgcolor 255 255 255 -canvas #14 #14 center ...

Double canvas resize doesn`t work.
Does anyone know how to make border (with two colors) in the nconvert?
