Hi,

I am trying to create an image with a specific bit depth to trial something to see if I can take it to a manufacturing process at work.
Long story short, I need finer control over the bit depth of my images.

I am using GIMP 2.10.20, can anyone help me with how to create an image with bit depths that are not available on the default precision drop down list?
(File -> New -> Advanced Options -> Precision)

At the moment I need a 4 bit per pixel bitmap image.
Is this even possible with GIMP?

Thanks in advance!

I am not sure if it is possible with Gimp. You could try putting the image into indexed mode with a 16 colour pallete, then export as a .bmp (with compatibility mode off - maybe)

Otherwise you probably need to use ImageMagick see: http://www.imagemagick.org/discourse-ser...hp?t=35655
