textmode.synth.js / SynthSource

Class: SynthSource

A chainable synthesis source that accumulates transforms to be compiled into a shader.

This is the core class that enables hydra-like method chaining for generating procedural textmode visuals. Each method call adds a transform to the chain, which is later compiled into a GLSL shader.

Example

Methods

Method	Description
charMap	Map character indices to a specific character set. This is the primary textmode-native way to define which characters to use.
charColor	Set the character foreground color using a color source chain.
char	Set the character indices using a character source chain. The number of characters is determined by charMap() if defined, otherwise falls back to the total characters in the layer's font.
cellColor	Set the cell background colors using a color source chain.
paint	Set both character foreground and cell background color using the same source chain. This is a convenience method that combines .charColor() and .cellColor() in one call.
clone	Create a deep clone of this SynthSource. Useful when you want to create a modified version of an existing chain without affecting the original.
brightness	Adjust brightness.
contrast	Adjust contrast.
invert	Invert colors.
saturate	Adjust color saturation.
hue	Shift hue.
colorama	Apply colorama effect (hue rotation based on luminance).
posterize	Posterize colors to limited palette.
luma	Apply threshold based on luminance.
thresh	Apply hard threshold.
color	Multiply all channels by a scalar value (grayscale).
r	Extract the red channel as a grayscale value.
g	Extract the green channel as a grayscale value.
b	Extract the blue channel as a grayscale value.
shift	Shift color channels by adding offset values.
gamma	Apply gamma correction for nonlinear brightness control.
levels	Adjust input/output levels and gamma for precise tonal control.
clamp	Clamp color values to a specified range for stability.
seed	Set a seed for deterministic randomness in this source chain.
add	Add another source.
sub	Subtract another source.
mult	Multiply with another source.
blend	Blend with another source.
diff	Difference with another source.
layer	Layer another source on top.
mask	Mask using another source.
screen	Screen blend with another source.
overlay	Overlay blend with another source.
softlight	Soft light blend with another source.
hardlight	Hard light blend with another source.
dodge	Color dodge blend with another source.
burn	Color burn blend with another source.
lighten	Lighten blend with another source.

scroll	Scroll coordinates in both X and Y directions.
scrollX	Scroll coordinates in X direction.
scrollY	Scroll coordinates in Y direction.
pixelate	Pixelate the output.
repeat	Repeat coordinates in both X and Y directions.
repeatX	Repeat coordinates in X direction.
repeatY	Repeat coordinates in Y direction.
kaleid	Apply kaleidoscope effect.
polar	Convert coordinates to polar space.
twirl	Twirl distortion with radial falloff.
swirl	Swirl distortion around a center.
mirror	Mirror coordinates across X and/or Y axes.
shear	Shear coordinates along X and Y axes.
barrel	Barrel distortion (bulge outward).
pinch	Pinch distortion (pull inward).
fisheye	Fisheye lens distortion.
