This is a tool for converting images to text. It supports two different conversion modes:
grayscale, a typical conversion onto a map of light to dark characters to produce a grayscale image.outline, a conversion onto visually similar characters done region-by-region, to help produce output that makes better use of negative space than the grayscale conversion.You can see the visual difference between the two modes on this image:
