FontForge can use Potrace to import a bitmap image into a font. Potrace is also used by the music engraving program LilyPond. An open-source progressive web app that uses Potrace is SVGcode. Potrace's input and output is black and white (colored images are greyscaled before processing). However, Inkscape is capable of producing color images by ...
max is the maximum value for color level in the input image within the selected kernel. min is the minimum value for color level in the input image within the selected kernel. [4] Local contrast stretching considers each range of color palate in the image (R, G, and B) separately, providing a set of minimum and maximum values for each color palate.
