Pigment

+ +![screenshot](./screenshot.png) + +

Color grading with code.

+ + +## Table of Contents + +- [Supported Platforms](#supported-platforms) +- [Usage](#usage) +- [Shaderlib](#shaderlib) +- [Commandline interface](#commandline-interface) +- [Known Issues](#known-issues) + + +## Supported Platforms + +- Linux + +You can find the latest release ... + +- [here (remotebranch.eu)](https://remotebranch.eu/ChaoticByte/Pigment/releases/latest) + + +## Usage + +With Pigment, you are processing images with GDShaders. This brings almost endless opportunities to create unique art. +If you want to learn GDShader, take a look at the [Godot docs](https://docs.godotengine.org/en/stable/tutorials/shaders/). + +**To get started, use the project template (see the Releases section of this repo) and open it in Godot.** + +The template includes many examples. You can use them as a starting-point to write your own stuff. + +Besides the regular GDShader stuff, Pigment has so-called directives. Those allow to further control the behaviour of the application. **The most important directive is `//!load` to load an image.** + + +### Load TEXTURE using the `//!load` directive + +```glsl +//!load +``` + +The main image file will be read and available as the sampler2D `TEXTURE`. + + +#### Load additional images + +```glsl +//!load+ + +uniform sampler2D ; +``` + +Have a look at the `place_texture.gdshader` example. + + +### Have multiple steps with `//!steps n` + +You can apply your shaderfile multiple times. At every additional step, `TEXTURE` is the result of the previous step. This can be used to chain effects that cannot be easily chained otherwise. + +To query the current step index, a `STEP` uniform is automatically injected. If `steps` is set to `0`, your shader won't be applied at all. + +Example: + +```glsl +//!load ... +//!steps 5 + +uniform int STEP; +uniform int STEPS; + +void fragment() { + if (STEP == 0) { + ... + } else if (STEP == 1) { + ... + } else if (STEP == STEPS-1) { + ... + } +} +``` + + +## Shaderlib + +This repo comes with a (still small) shader library including pre-written functions and more. +Have a look at the `shaderlib` folder. + +Here is an example: + +```glsl +shader_type canvas_item; + +#include "./shaderlib/oklab.gdshaderinc" + +//!load ./images/swamp.jpg + +void fragment() { + vec4 oklab = rgb2oklab(COLOR); + vec4 oklch = oklab2oklch(oklab); + oklch.z -= 2.0; + COLOR = oklab2rgb(oklch2oklab(oklch)); +} +``` + + +## Commandline interface + +You can run Pigment from the commandline or scripts. + +> Note: Headless mode is not supported. Using the commandline interface still opens a window. + + +### Usage + +``` +~ Pigment CLI ~ +-================- + +Usage: + +./Pigment + +Commands: + + help + + | Shows this help text. + + apply --shader PATH --input PATH --output PATH + + | Applies a shader file. + + --shader PATH The path to the shader + --input PATH The path to the input image. + Passing a folder activates batch mode. + --output PATH Where to write the resulting image to. + In batch mode, this must be a folder. + +``` + + +### Batch Mode + +Since version v8.0, you can pass a directory to `--input` and `--output`. This will process all images in the input directory and write the output to the output directory. + +> Note: You *can* use this feature for video frames, but it will take a loooong time. + + +#### Examples + +``` +./Pigment apply --shader ./examples/oklab.gdshader --input ~/Pictures/test.png --output ./output.png +``` + + +## Known Issues + +- screen scaling is unsupported; Using screen scaling could lead to an either blurry UI, or no scaling at all -> see #45 +- commandline interface: `--headless` is not supported diff --git a/build-template/Containerfile b/build-template/Containerfile new
