This workshop is designed to go over the **most commonly used functions** with [Ronin](https://github.com/hundredrabbits/Ronin). The list of all available functions and their usage is located [here](https://github.com/hundredrabbits/Ronin/#library).
- **Part 1**: [Images](#Images) `(open)`, `(import)`, `(crop)`, `(export)`
- **Part 2**: [Draw](#Draw) `(stroke)`, `(fill)`, `(gradient)`, `(clear)`
- **Part 3**: [Filters](#Filters) `(pixels)`, `(saturation)`, `(convolve)`, `(sharpen)`
- **Part 4**: [Events](#Events) `(on)`, `(on "mouse-move")`, `(on "animate")`, `(on "/a")`
## Images
This section will teach the basics of opening, cropping and saving an image file. You can use the `$path` help to quickly get an image's path into Ronin, by writing `$path` and dragging a file onto the Ronin window.
### Open
To import an image, and resize the canvas to fit the image size, type the following text, drag an image file onto the Ronin window and press `cmd+r`:
```
(open $path)
```
### Import
To import an image onto the current canvas, type the following text, drag an image file onto the Ronin window and press `cmd+r`:
```
(import $path
(rect 50 100 250 200))
```
The previous code will import an image, and position it at `50,100`, at a size of `250x200`. Alternatively, you could use a `(pos)` to position the image and not resize it.
```
(import $path
(pos 50 100))
```
### Crop
To crop the canvas, type the following text, drag an image file onto the Ronin window press `cmd+r`:
```
(import "~/Desktop/photo.jpg"
(pos 50 100))
(crop (rect 50 50 300 300)
```
Alternatively, you could select the cropping area with the cursor with the following code, and selecting an area in the canvas:
```
(import "~/Desktop/photo.jpg"
(pos 50 100))
(crop $rect)
```
### Export
To export the resulting image, type the following text, drag an image file onto the Ronin window, then drag a folder and add the new file's name, and press `cmd+r`:
```
(import $path
(pos 50 100))
(export $path)
```
For example, a version of that same code with file paths, might look something like:
```
(import "~/Desktop/photo.jpg"
(pos 50 100))
(export "~/Desktop/export.png")
```
