I have been using Gimp - Index color - to generate GGA palette, dithered images. Sometimes that works great right out of the box, but often times I have to do a lot of manual changes. Your software is great because I can make all those adjustments - like brightness and contrast in particular - and see the results in real time.
I still have to do some manual fixes afterwards, but it is so minor in comparison that I don't know if it's worth mentioning.
I plan on playing around with the custom palette option, since I am using CGA mode 5, which uses red instead of magenta. I will let you know how that works out.
In general, it's a nice tool that I think I will be using a lot. At least on my current project.
I’m glad that it’s useful for you! Thanks for giving the tool a go :)
I used a similar workflow with Photoshop and Index Color and had the same problems. It was just too many steps and extra tuning needed for most images. That’s why I wanted a tool fully focused on this task where I can quickly experiment.
