<p align=center>Create image filters by writing shaders.</p>
|
|
|
|
## Supported Platforms
|
|
|
|
- Linux
|
|
|
|
You can find the latest releases [here](https://github.com/ChaoticByte/Fragmented/releases/latest).
|
|
|
|
## Usage
|
|
|
|
The repo includes examples. You can use them as a starting-point to write your own filters.
|
|
Just load an image using `//!load`, edit the shader code and hit `F5` to see the changes.
|
|
|
|
### Load TEXTURE using the `//!load` directive
|
|
|
|
```glsl
|
|
//!load <filepath>
|
|
```
|
|
|
|
The image file will be read and available as the `TEXTURE` variable.
|
|
|
|
#### Load additional images
|
|
|
|
```glsl
|
|
//!load+ <name> <filepath>
|
|
uniform sampler2D <name>;
|
|
```
|
|
|
|
Have a look at the `mix.gdshader` example:
|
|
|
|
```glsl
|
|
shader_type canvas_item;
|
|
|
|
//!load ./swamp.jpg
|
|
|
|
//!load+ img2 ./overlay.jpg
|
|
uniform sampler2D img2: repeat_enable, filter_nearest;
|
|
|
|
void fragment() {
|
|
COLOR = mix(COLOR, texture(img2, UV), .2);
|
|
}
|
|
```
|
|
|
|
## 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 on how to use it (the `hsv.gdshader` example):
|
|
|
|
```glsl
|
|
shader_type canvas_item;
|
|
|
|
#include "res://shaderlib/hsv.gdshaderinc"
|
|
|
|
//!load ./swamp.jpg
|
|
|
|
void fragment() {
|
|
COLOR = hsv_offset(COLOR, 0.32, 0.2, 0.0);
|
|
}
|
|
```
