Choose an image to convert.
The game expects 4 colors, the colors from your input are reduced based on this palette, finding the closest match from the original pixel to one of these 4.
Enable picking, choose a slot, then click on the original above the preview to sample a pixel color into that palette entry.
Adjust color distance to ignore similar colors, try higher numbers for images with diverse colors, or lower if the image has mostly similar hues.
Allows you to override one color from the main palette to another color, so the automatically chosen color can be changed, and, in essence, manually painted.
Note that a completely white color is treated as transparent in-game, which uses your chat background color, it also automatically trims excess transparency making the visual chat box smaller as needed.
Adjust to shift the image vertically
Higher threshold = fewer pixels treated as edges (more dithering). Lower = more edge protection (less diffusion).
Offsets the Bayer pattern around mid-gray; small shifts can improve gradients for specific images.
