Glyphtrix processes images and videos by analyzing the canvas. It applies image adjustments like brightness and contrast, then segments the visual into a grid determined by the "Density" setting. Each grid cell's average brightness is converted to a corresponding character from the selected "Character Set". These characters are then rendered with chosen colors and fonts to create the final ASCII art output.
