chafa: Improve image rendering with small color palettes using dithering.

chafa

$ chafa -c 16 --dither ordered ${filename}

try on your machine

The command you mentioned, chafa -c 16 --dither ordered ${filename}, is executed in a command-line interface (CLI).

Here is a breakdown of each component:

chafa: This is the command being executed. Chafa is a utility that generates image previews directly in the terminal. It converts images into text-based representations, allowing you to view images even in CLI.
-c 16: This option specifies the number of colors to use for the image. In this case, it is set to 16, which means the image will be rendered using a limited color palette of 16 colors.
--dither ordered: This option enables dithering during the conversion process. Dithering is a technique used to simulate colors that are not present in the chosen color palette. In this case, ordered dithering algorithm is likely used.
${filename}: This is a placeholder for the filename of the image you want to convert. You should replace ${filename} with the actual filename or path to the image file.

By executing this command, Chafa will convert the specified image into a text-based representation using a limited color palette of 16 colors. It will also apply ordered dithering to simulate additional colors not present in the palette.

This explanation was created by an AI. In most cases those are correct. But please always be careful and never run a command you are not sure if it is safe.
