Library of images to use as OFFIMG screens on the DM41X and DM42
Forum rules
Do you have a creative streak? Post your OFFIMG photos here.
Images MUST be in Windows-NT .bmp format at a resolution of 400x240 pixels and 1-bit colour depth or they will not be displayed by the DM42. Images that do not meet this requirement will be removed from the forum
As I don't even have a system using Windows NT what else can I use to produce OFFIMG pictures of Windows-NT.bmt of 400 x 200 pixels and 1 bit color depth?

AFAIK you can use PAINT (available on each and every Windows PC) and store your file as monochrome .BMP.

Paint has no dithering. You'll get just black and white patches.

If I buy someone a drink to congratulate them, is it a Mazel Tov cocktail?

Sorry I didn't recognize your unwritten wish But I faintly remember someone wrote about this topic on this forum, IIRC. Maybe worthwhile searching ...
Start by converting to greyscale at the required resolution of 400x240, then convert to 1-bit depth with Floyd-Steinberg dithering and you'll get pretty good results.

So it is best to convert to grayscale before converting to 1-bit depth? I tend to start with whatever image cropped (or sometimes padded) to the correct aspect ratio of 1.667:1. Then open in GIMP and scale to 400x240. Then I try the conversion to 1-bit (using Image->Index->Convert Image to Indexed Colors, select “Use black and white (1-bit) palette” with Floyd-Steinberg dithering). This of course converts a color image to black and white. If that looks good, I export to a bmp. More often than not, I undo the conversion, then mess with contrast and brightness in the color tools and try again. I do that a few times until I am satisfied, then export. I have not found a magic formula for adjusting the brightness and contrast to produce the best results. Sometimes I then open in paint to remove excess speckles from areas that are supposed to be totally black or otherwise touch things up. Finally copy to DM42 OFFIMG folder.
All in all, I probably take this much too seriously!
