From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

I think that as a photo editor, GIMP is the best option for open source. But as a print designer the lack of being able to work in CMYK and 1 bit images is a big problem.
Fortunately Krita does the CMYK thing extremely well, but it also lacks the ability to handle 1 bit images.
Wondering if anyone out there has discovered a lesser known open source app that works with 1 bit images well? Maybe something made for old school pixel art?
It seems strange to me, since even a more modern format like png supports 1 bit.
Maybe for 1 bit images on GIMP you could try setting the image mode to indexed and then generate a palette with just two colors. GIMP can also apply dithering if you want
Thank you!! That is exactly what I was looking for.
That is a big help. I was stuck on the idea that that option wasn't available when making a new doc and didn't think to look under the change mode menu.
