C library used to glitch images with the help of libgoimg and LuaJIT.
A driver program is included to play around with the library. The build script compiles both the library and the driver program. You can obtain the driver program's usage (from the library's root path) with:
$ ./driver/cdhorizon
The possible output format strings are:
- farbfeld
- PNG
- JPEG
- libgoimg
- LuaJIT
- libjpeg (optional)
- libpng (optional)
Building this project requires tup. Compile the library with:
$ ./make build
To change the compilation flags, create a tup.config file with the
following content:
CONFIG_CC=...
CONFIG_CFLAGS=...
CONFIG_LDFLAGS=...
If you want libpng and/or libjpeg support on the driver program,
creating this file with the appropriate CONFIG_LDFLAGS is required.
If you're just building the library, you can ignore this step.
| Identifier | Arguments | Return | Description |
|---|---|---|---|
horizon.getpixel |
x, y |
pixel |
Returns a table with the RGB color components of the specified pixel. |
horizon.setpixel |
x, y, pixel |
N/A | Takes an input table with the RGB components of the pixel to set. |
horizon.width |
N/A | width |
Constant value of the width of the input image. |
horizon.height |
N/A | height |
Constant value of the height of the input image. |
horizon.params |
N/A | params |
Returns a dynamic table with user defined script param values. |
Some examples can be found at glitchers/. The file glitchers/id.lua creates
an exact replica of the input image, so it is a fine template for new scripts.
