By the way… there are many shade styles available in [orx/orx-shade-styles at master · openrndr/orx · GitHub](https://github.com/openrndr/orx/tree/master/orx-shade-styles) so you don’t need to write shaders yourself (many of them only available when using version 0.4.5).

I opened [this issue](https://github.com/openrndr/orx/issues/359) to be able to apply those same shade styles to strokes, not only fills.

Meanwhile I just figured out a little hack:

```kotlin
val img = loadImage("data/images/cheeta.jpg")
val ss = imageFill { image = img }
ss.fragmentTransform = ss.fragmentTransform?.replace("x_fill", "x_stroke")

```

Here I load an image and use the new `imageFill` shade style which works for fills only. But then in the next line I replace any mentions of x\_fill to x\_stroke and voilá! Now the style applies to lines instead 🙂
