I wish GIMP still worked the way it used to! Now I'm trying to use XnView but my images come out as 52KB. A real background image is 13KB. My image is 400x240. I choose color depth binary and Floyd Steinberg dithering with neither 24 bits nor 32 bits checked. What else can I set to make this work?STS-741 wrote: ↑Wed Nov 11, 2020 10:50 amI use Pierre-Emmanuel Gougelet's XnView (Ver. 2.49.4) software for this, which is available as freeware for several operating systems. It's easy to use and has been translated into 46 languages. The program is also freely available in a portable version.

Re: Converting to 1-bit
With XnView, it works for me if I export the picture (instead of saving, which forces 24-bit conversion).
File - Export - Tab BMP (all options unchecked), color mode = black & white - Save - Record...

Re: Converting to 1-bit
That worked. Thanks! I never did like the way GIMP took so long to start. I put up with it because that was the only way I was used to creating backgrounds.

Re: Converting to 1-bit
Well Gimp is still great for lots of things. I don't mind the short xconvert step now that I know how to do it. Thanks for confirming the gimp issue because I thought I was doing something wrong.

Thanks for updating it to Python 3! I should pull your changes at some point when I get the motivationreavy wrote: ↑Fri Nov 06, 2020 9:51 pmI found this thread while looking for tools to easily convert to 1-bit BMPs for my DM42. I had good luck with tgray's hyperdither. I forked it and made a small revision to get it to work with Python 3.

I always loved the way Atkinson dithering looked. It reminds me of being a kid and playing on the classic Macs at my dad’s work. So I implemented it for myself when I got a DM42. Fun learning project.
My code is here for anybody who wants it:
