Hi guys,

I need some help in converting a mixed color text+photo PDF to 16 shade grayscale & to trim the borders, headers & footers as much as possible, for viewing on my Onyx Boox M96.

The text has a color background, so the re-flow option creates grey colored strips of black text over a white background.

I gave up on re-flow & tried to do a simple grayscale + trim job, but although using the GUI, it shows the preview as black & white, the output is still color.

I switched to command line with the shortcut method, dropping the files on the shortcut already updated with the options. When I ONLY use the option -c-, then the output is grayscale, but re-flow occurs, with grey color strips of text. When I omit -c-, the output is still color. When I use any other option with -c-, like -wrap-, or -t, the output is again color.

PM'd the link to the file to Willus.

Please help. I'm at my wits end.
