TEXture PROcessing MAchine

TEXPROMA is a stack machine. All operators pop their arguments and push their results onto the stack.

Image generators

• noise : (a : integer, b : integer) ↦ mono-buf

• light : (a : integer, b : float) ↦ mono-buf

• plasma : () ↦ mono-buf

• perlin-noise : (a : integer) ↦ mono-buf

• sine : (a : float) ↦ (mono-buf)

  Generates vertical sine wave of amplitude a (range [-1.0, 1.0]).

Buffer operators

• rotate : @mono-buf ↦ @mono-buf

  Rotates buffer clock-wise by 90 degrees.

• flip : @mono-buf ↦ @mono-buf

  Flips buffer vertically.

• move : (@mono-buf, float, float) ↦ (@mono-buf)

• explode : color-buf ↦ (mono-buf, mono-buf, mono-buf)

• implode : (mono-buf, mono-buf, mono-buf) ↦ color-buf

• insert : (color-buf, mono-buf, integer) ↦ color-buf

• extract : (color-buf, c : integer) ↦ (color-buf, mono-buf)

  Extracts component c (for R : 0, G : 1, B : 2) from color buffer.

• repeat : (@mono-buf, integer, integer) ↦ (@mono-buf)

Pixel operators

• add : (@mono-buf, @mono-buf) ↦ (@mono-buf)
• mul : (@mono-buf, @mono-buf) ↦ (@mono-buf)
• max : (@mono-buf, @mono-buf) ↦ (@mono-buf)
• mix : (@mono-buf, @mono-buf, integer) ↦ (@mono-buf)
• invert : (@mono-buf) ↦ (@mono-buf)
• mix-map : (mono-buf, mono-buf, mono-buf) ↦ (mono-buf)
• shade : (mono-buf, mono-buf) ↦ (mono-buf)

Color operators

• sine-color : (@mono-buf, integer) ↦ (@mono-buf)

• hsv-modify : (color-buf, float, float) ↦ (color-buf)

• contrast : (@mono-buf, float) ↦ (@mono-buf)

• brightness : (@mono-buf, float) ↦ (@mono-buf)

• grayscale : color-buf ↦ mono-buf

  Converts color buffer to mono buffer (aka grayscale).

• colorize : (mono-buf, c1 : integer, c2 : integer) ↦ color-buf

  Maps input image pixels onto color range between c1 and c2. Colors are encoded as hex numbers 0xRRGGBB.

Distortion operators

• twist : (@mono-buf, float) ↦ (@mono-buf)
• distort : (@mono-buf, mono-buf, mono-buf, float, float) ↦ (@mono-buf)

Filters

• edges : (@mono-buf) ↦ (@mono-buf)
• emboss : (@mono-buf) ↦ (@mono-buf)
• sharpen : (@mono-buf) ↦ (@mono-buf)
• blur-3x3 : (@mono-buf) ↦ (@mono-buf)
• blur-5x5 : (@mono-buf) ↦ (@mono-buf)
• gaussian-3x3 : (@mono-buf) ↦ (@mono-buf)
• gaussian-5x5 : (@mono-buf) ↦ (@mono-buf)
• median-3x3 : (@mono-buf) ↦ (@mono-buf)
• median-5x5 : (@mono-buf) ↦ (@mono-buf)

Input-output

• save-mono : (mono-buf, string) ↦ ()
• save-color : (color-buf, string) ↦ ()
