ASCIIPIC

ASCIIPIC is a high-performance command-line tool written in Go that converts images into ASCII art. It supports true-color terminal output and includes a specialized PNG exporter that applies a background luminosity effect, producing vibrant, high-contrast results suitable for sharing.

Renders ASCII art in the terminal using 24-bit ANSI color codes, preserving the original image's color palette.

Exports ASCII art to PNG with a custom glow rendering engine. This engine fills the background of each character cell with a dimmed version of the image color, preventing exported art from appearing too dark or washed out.

Includes 15 character sets ranging from classic ASCII to Braille patterns, block elements, and mathematical symbols.

Complete control over output width, font size for PNG export, and brightness adjustment.

Supports JPEG and PNG input files.
