I need this feature too. Similar to prior threads from here and long ago closed I have to create monochrome (1-bit per pixel) BMP files frequently for use on a low resolution FSTN LCD panel. One thing that is important to me though is to change the color pallet of the workspace to be monochrome as well. I need to be able to paste text (typically Asian characters at 8,9, or 10 point) and have them properly rendered. When creating text in most 'paint' apps, this will include grey levels to help render diagonals better but I don't want this. Paint does this very well (Save as Monochrome Bitmap, create text box, paste it from Notepad++ in UTF8 format), then I can check/adjust the canvas size and save it.
And it wouldn't matter if I was on a Mac or Windows or iPad.... I still want to export that monochrome bitmap. IN FACT I'd very much LIKE to have it on iPhone or iPad or Android tablet: Grab a screenshot, clip an area and save as bitmap.
This feature is easier than 99% of the other features in the app, why not do it?
I half expected to see BMP export after all the discussion and suggestions for V1 to include it. That thread is closed, so here is my official suggestion for BMP export support to be included in V2.
It's the standard for several Industrial Controls software packages and using MS Paint or IrfanView breaks my workflow and creates unnecessary intermediary files.
Thanks for listening.
