I was checking to see if resampling was being done and how accurate it is and how it differs from if I resampled the image in alternate software to account for resizing and dpi (scan interval).
It appears pass-through processes greyscale 8 bit as 1 bit. I verified the gcode as well, it’s just on or off. I tried BMP and JPG, I know for certain the image is 8 bit greyscale.
I guess if resampling is being done and it’s a good algorithm, then no need for me to resample, but I need to pre-process anyway, thought it might be worth studying if LB does it accurately.
