ASCII Settings

Configure the ASCII text overlay appearance

Font Size

Controls the size of the monospace characters. Smaller sizes = more characters = more detail. The grid automatically recalculates when you change font size.

Line Height

The vertical spacing between lines. Default is 0.78 (tight). Lower values pack lines closer together for a denser look.

Letter Spacing

Horizontal spacing between characters. Default is 0.06em.

Color

The base color of the ASCII text. Works in combination with the blend mode.

Opacity

How visible the ASCII layer is over the background image. Default is 0.38 for a subtle overlay.

Blend Mode

How the ASCII text composites with the background image:

  • Screen — additive blending, text lightens the image (default)
  • Normal — opaque text on top of the image
  • Multiply — darkening blend

Character Ramp

The set of characters used to represent brightness levels. Darker areas of the image use denser characters (like #, @), lighter areas use sparser ones (like ., ).
