# stipple_gen
|
||
|
|
|
||
|
|
A friendly fork of StippleGen_2 from Evil Mad Scientist Laboratories.
|

|

|
|
|
||
|
|
This script takes an image, provided as a JPEG, a PNG or a TIFF (generated by Processing) and outputs both an SVG for a plotter as well as a approximation as a JPEG, PNG or TIFF.
|
||
|
|
|
||
|
|
There have also been features added to do the following:
|
||
|
|
|
||
|
|
* **Custom output SVG scale**
|
||
|
|
* **Custom canvas size**
|
||
|
|
* **Option to fill in circles**
|
||
|
|
|
||
|
|
# Usage
|
||
|
|
|
||
|
|
`stipple_gen` is designed to be configured and run from the command line, rather than the GUI provided in the original sketch.
|
||
|
|
By creating a config.txt file in your sketch directory *OR* providing command line arguments to your sketch you can set all of the variables accessible to the GUI in the original StippleGen_2 sketch and then some.
|
||
|
|
|
||
|
|
An example using the helpful `stipple_gen.sh` script provided by this project.
|
||
|
|
|
||
|
|
```bash
|
||
|
|
bash stipple_gen.sh --display true --inputImage myImage.jpg --outputImage myStippledImage.jpg --outputSVG myStippledDrawing.svg
|
||
|
|
```
|
||
|
|
|
||
|
|
This will take your original image `myImage.jpg` and run it through the stippling process using the default variables for everything and output two files for you: `myStippledImage.jpg` and `myStippledDrawing.svg`, the latter of which you can use on your plotter.
|
||
|
|
|
||
|
|
Other variables:
|
||
|
|
|
||
|
|
```java
|
||
|
|
|
||
|
|
public int canvasWidth = 800;
|
||
|
|
public int canvasHeight = 600;
|
||
|
|
|

|
|
public boolean display = true;
|

public int windowWidth = 800;
