## How it works

Converts images into ASCII text characters based on pixel brightness.

Analyzes pixel brightness to map characters accordingly. Sliders adjust character resolution and contrast with export to text file.

Extracts pixel data using an HTML5 canvas. Calculates brightness from RGBA values and maps each section to a character palette ordered by density.
