Upload an image file to posterize it into a grayscale PNG image with a specified number of shades.
Gray values are equally spaced for maximum targetability in HueForge.
For transparent PNGs, add 1 to the Number of Grays
This is a preprocessing tool for HueForge to help separating colors so they may be more easily targeted.
It is mostly used for flat color images, like signs, cartoons, illustrations, etc..
You may have to adjust the number of colors as quantization is sometimes not correct.
Choose the number of colors then Choose File and upload your image.
You can then change the number of Grays on the fly.
